Ferocious wildfires consume millions of

hectares of land. Relentless droughts

choke the

rivers. Yet amid this unforgiving

landscape, some of the most bizarre and

formidable predators fight for survival

every

second.

Australia, a land where nature has

forged the world's most fearsome

hunters. Where the largest reptile lies

motionless beneath the river's surface,

waiting for the perfect moment to

strike. Where silent serpents glide

through the grass, carrying the most

potent venom on Earth. But they are not

the true rulers of this harsh continent.

Before we dive into the even more

formidable creatures that call this

place home, let us know where you're

from in the comments.

Welcome to wild Australia, the continent

of the strangest predators.

[Music]

The sun burns red over the eucalyptus

forests where wildfires still smolder

beneath layers of ash. Heat rises from

the cracked earth while in the distance

a lone dingo silently watches its prey.

It is Australia's dominant land predator

now. But that was not always the case.

[Music]

30,000 years ago, the marsupial lion

terrorized this continent. A fearsome

pouched predator with an incredible bite

force. But it has long since vanished.

Now, this unforgiving land is witnessing

a new wave of extinctions. In just three

centuries, over 100 endemic species have

disappeared.

Forests are shrinking. Wildfires rage

with greater intensity. And invasive

species are disrupting the delicate

balance of

nature. Feral cats move like shadows,

hunting tiny bilbees with razor sharp

claws.

Red foxes brought from Europe stalk the

legendary night parrot. A species

already teetering on the edge of

existence. A world where outsiders

replace the natives. Where nature is

reshaped by human

hands. Yet even amid destruction,

Australia's native creatures fight

relentlessly to survive. Unlike other

continents where apex predators like

tigers and bears rule through sheer

power, Australia has taken a different

evolutionary path. Here, survival

belongs to those who rely on strategy

and adaptation rather than brute

strength.

Heat.

[Music]

Here every species is uniquely designed

to thrive in a world of extremes. There

is no need for giant beasts. This land

remains a stage for some of the

strangest and most formidable predators

Earth. Australia, a vast and solitary

continent, stretches across the open

ocean isolated from the rest of the

world for millions of years. Covering an

area of 7.68 68 million km. Australia is

the smallest continent on Earth. Yet, it

is also the sixth largest country by

land area. Its coastline extends over

35,877 km, embracing towering cliffs,

sprawling coral reefs, and vast

wetlands. Offshore, Australia's

exclusive economic zone spans

8.148 million square kilm, reaching into

the deep waters of the Indian and

Pacific

oceans. From above, Australia unfolds

into three distinct geographical

regions. To the west lies a vast plateau

of ancient rock formations where the sun

bakes the earth to over 40° C in the

height of

summer. At the continent's center

stretches a low-lying arid expanse

dominated by endless deserts where

towering sand dunes ripple like frozen

waves. To the east, the great dividing

range runs along the coastline, giving

rise to lush tropical rainforests, cool

highlands, and winding rivers that weave

their way toward the

ocean. Millions of years ago, Australia

was not the isolated land mass it is

today. In the distant past, it was once

part of Rodinia, an ancient superc

continent that formed around 1.1 billion

years ago. As Rodinia broke apart,

tectonic plates drifted, collided, and

merged once more. Eventually, they

formed Gonduana, a vast land mass that

connected Antarctica, South America,

Africa, India, Madagascar, and

Australia.

The terrain of this continent was

reshaped until around 4,600 years ago.

The last volcanoes on the eastern

mainland were still active. And even

today, on distant islands such as Herd

and Macdonald, molten lava continues to

flow silently beneath the ocean

floor. Australia's geological system

reflects its history spanning billions

of years. Its continental crust was

formed through three major tectonic

cycles from the ancient cratons in the

west to the younger mountain ranges in

the

east. The oldest rocks in Western

Australia date back more than 3.7

billion years lying undisturbed beneath

the fiery red terrain of the

Pilburraton.

Farther south in Jack Hills, the oldest

zirkan crystals on Earth have been

discovered, dating back 4.4 billion

years, nearly as old as the planet

itself. These ancient rocks are remnants

from Earth's earliest days when the

planet was newly formed and covered by

primordial oceans.

[Music]

This isolation has given rise to one of

the most unique ecosystems in the world.

More than 87% of mammals, 93% of

reptiles, 94% of amphibians, and 45% of

birds on this continent are endemic

species.

These creatures have evolved to survive

in an unforgiving environment where

water is scarce, temperatures fluctuate

drastically, and food sources are not

always abundant.

[Music]

[Applause]

[Music]

In the vast grasslands and savylvanas

stretching under the relentless sun, the

cracked earth waits for unpredictable

rains. Herds of marsupials migrate in

search of water. Scorching winds carry

the red dust of the continent. This is a

world in constant motion. Summer here is

unforgiving. Daytime temperatures can

soar to 45° C, and the ground becomes so

hot it can sear footprints into the

[Music]

sand. Annual rainfall averages between

250 to 500 mm, but it is unevenly

distributed. Some regions may endure

months without a single drop of rain.

Others experience sudden downpours,

transforming barren plains into fertile

landscapes within days. The soil here is

nutrient poor and struggles to retain

moisture. Plants have adapted by

developing deep roots to access water

from lower soil layers or evolving small

leaves to minimize water loss.

[Music]

Amid this harsh landscape in

southeastern Australia, towering

eucalyptus trees reach skyward against

the deep blue expanse. These forests

stretch from Victoria and New South

Wales to Tasmania, covering nearly 77%

of the continent's total forested area.

Winding trails cut through the forest,

offering a gateway to the world of

eucalyptus forests. Long hiking tours

take visitors beneath the cool shade of

the canopy, where bird song fills the

air, wildlife tracks weave through the

undergrowth, and nature's grandeur

unfolds at every turn. Some trails lead

to hidden waterfalls deep within the

forest where cool streams cascade down

from the highlands, forming crystalclear

pools. These are ideal resting spots to

observe the rich biodiversity. From

brightly colored birds to reptiles

concealed beneath fallen

leaves. In the shade of the towering

eucalyptus trees, the howl of a dingo

echoes through the stillness. Other pack

members respond with shorter calls,

confirming their locations before the

hunt

begins.

Over 8,300 years ago, the ancestors of

the dingo followed humans migrating from

Asia to this

land. But unlike other domestic dogs,

the dingo was never fully tamed. It

became a wild predator, developing its

own survival instincts and rising to the

top of Australia's food

chain. As strategic hunters, dingoes

work together to take down larger prey.

They use coordinated tactics to trap

their target, cutting off all escape

routes.

In livestock regions, dingoes are not

seen as nature's guardians, but as a

threat. To protect cattle and sheep, the

dingo fence was built in the late 19th

century, stretching over 5,600 km,

making it the longest fence in the

world. This barrier cut off dingoes from

vast eastern lands, altering ecosystems

on both sides. Some dingo packs have

survived and adapted by hunting smaller

prey, expanding their territories,

learning to evade traps, and finding

food more efficiently. Some individuals

have even learned to leap over lower

sections of the fence or dig through

gaps, continuing their journey as the

continent's apex predator. If dingoes

are not native to Australia, do you

think they should still be protected as

part of the ecosystem?

In spring, as the first rains awaken the

forests after the dry season, the

eucalyptus forests become the stage for

nature's most breathtaking

performances. The wedge-tailed eagle,

Australia's largest eagle, circles high

above, using its razor sharp vision to

scan the ground below.

With eyesight capable of spotting prey

from over 1 kilometer away, it tracks

the movements of walabes, rabbits, and

young kangaroos that have strayed from

their groups. Within seconds, a

high-speed dive begins. Its powerful

talons locking onto prey with a grip

strong enough to secure it upon

landing. When facing larger prey such as

adult kangaroos, these eagles do not

hunt alone. A pair of wedge-tailed

eagles will coordinate their attack. One

pursues and drives the target toward the

other, where a precisely timed strike

ends the chase. Their success rate in

open grasslands reaches

67%, an impressive figure in the world

of predators.

[Music]

Off the coast of Queensland near

Townsville, Magnetic Island rises from

the sea like an ecological paradise.

Covered in ancient granite formations,

this island is part of the tropical dry

forests of northeastern Australia. Here,

pristine eucalyptus woodlands blend

seamlessly with untouched coastlines,

creating a unique habitat where wildlife

has perfectly adapted to the harsh

climate. Trails like Fort's Walk lead

visitors through dense eucalyptus

forests, climbing up rugged cliffs to

panoramic views over the vast coral sea.

Horseshoe Bay, Radical Bay, and Florence

Bay are standout destinations.

These are places where visitors can

immerse themselves in crystal clearar

waters, snorkel among coral reefs, or

simply relax in the tranquil embrace of

[Music]

nature. The eucalyptus trees on the

island are more than just part of the

landscape. They are the lifeline for one

of Australia's last wild koala

populations.

[Music]

High among the branches, nestled within

the deep green canopy, koalas cling to

tree trunks, slowly nibbling on

eucalyptus leaves, a diet rich in fiber

but low in

nutrients. Magnetic Island is home to

one of the last remaining wild koala

populations in

[Music]

Australia. Over 30 million years ago,

the common ancestor of koalas and

wombats appeared on the Australian

continent. As eucalyptus forests spread

across the eastern regions, this

marsupial evolved to thrive on a

uniquely specialized diet. Eucalyptus

leaves, which are nearly indigestible to

most animals, became the primary food

source for koalas. Their digestive

system developed an enlarged seeum

filled with bacteria that helped break

down toxic compounds in the

[Music]

leaves. Gradually, this tree dwelling

marsupial adapted to life high in the

canopy, avoiding ground predators and

leading an isolated existence among the

treetops.

Today, koalas are primarily found along

eastern and southeastern Australia from

Queensland to Victoria, but their

numbers are declining

[Music]

rapidly. According to the Australian

Koala Foundation, the national koala

population was estimated to be between

32,000 and 58,000 in 2021, a significant

drop from over 80,000 in 2018.

Climate change, wildfires, and habitat

loss due to urbanization have greatly

reduced their traditional

habitats. On the mainland, deforestation

for agriculture and infrastructure has

fragmented their forests, isolating

koalas in small, scattered woodlands and

cutting off their natural movement

corridors. Koalas play a vital role in

the eucalyptus forests. By feeding on

the leaves, they help regulate tree

growth and support the natural

regeneration of the forest. However,

with their numbers dwindling, the entire

ecosystem faces concerning changes. A

decline in koala populations could

disrupt the food chain, affecting the

growth of both plants and animals that

rely on the same habitat. On Magnetic

Island, conservation programs are

underway to protect the remaining koala

population. Green corridors have been

established, allowing koalas to move

safely away from roads and urban areas.

Wildlife rescue groups actively treat

injured koalas, particularly those

affected by wildfires or diseases such

as chlamydia, a common infection that

can cause infertility, and reduce

reproductive rates. Additionally,

community education programs are raising

awareness about the importance of

protecting this iconic species.

[Music]

Back on the mainland, the western

grasslands stretch from the coast of

Western Australia deep into the

interior. Unlike the lush, temperate

grasslands, this region holds a raw,

untamed beauty, where ecosystems have

adapted to semi-arid conditions and

prolonged droughts under their own

unique set of rules. Along the winding

trails, visitors can walk through a

landscape of low-lying grasses and hardy

[Music]

shrubs. Here, wildlife observation areas

offer the perfect vantage point to

witness a wedge-tailed eagle soaring

overhead or a walabe bounding across the

open

fields. Amid the untouched wilderness,

the parent lies still in the shade of

sunscched rocks, blending seamlessly

with the sandy

terrain. This is the largest lizard on

the continent, reaching up to 2.5 m in

length and weighing around 20 kg. During

the harsh summer months when ground

temperatures soar beyond 50° C, the

parent seeks refuge in deep burrows to

escape the intense

[Music]

heat. These burrows not only help

regulate their body temperature, but

also serve as safe havens from airborne

predators such as raptors scanning the

land from above.

The parent is one of the apex predators

of these vast grasslands. When an

unsuspecting rabbit or bilbye crosses

its path, the hunt is over in an

instant. It can reach speeds of 40

kmh, fast enough to chase down small

prey or escape from threats. Its mild

venom is powerful enough to weaken its

prey before delivering the final blow.

[Music]

The hot inland winds sweep across the

vast grasslands of the Gulf Savannah,

stretching from Northern Queensland to

Australia's Northern Territory. This

land, once part of a massive coral reef

over 400 million years ago, is now one

of the continent's most pristine savas.

The dry earth, low-lying grasses, and

scattered shrubs form a distinctive

semi-arid

ecosystem. And imagine you're walking in

a rainforest and suddenly a creature

almost 2 m tall stands before you. What

is it? The answer is kangaroo, the

iconic animal of Australia.

They are the only group of mammals in

the world that use hopping as their

primary form of

movement. Over 20 million years ago, the

ancestors of kangaroos lived in dense

forests. But as Australia's climate

became drier, forests gave way to

grasslands and

savas. Kangaroos evolved to adapt to

this new terrain. Instead of walking on

all fours like other marsupials, they

developed powerful hind legs and a long

tail for balance, allowing them to move

by hopping. This is a more

energyefficient method compared to

running across arid

[Music]

landscapes. Three major kangaroo species

share the Gulf savannah. The eastern

grey kangaroo is the most common. Agile

and lightweight, they live in large

groups and are most active at dawn and

dusk, avoiding the heat of the

day. The western gray kangaroo is

slightly smaller, has a darker brown

coat, and is more commonly found in open

woodlands. Meanwhile, the red kangaroo,

the largest species in the macropod

family, has a distinctive reddish coat

in adult males. The largest individuals

can stand 1.8 m tall, weigh up to 90 kg,

and reach speeds of 56 km per hour,

covering up to 9 m in a single

[Music]

leap. Adult male kangaroos frequently

engage in battles to establish dominance

and mating rights. These fights

typically begin with punches using their

forlims, but as tensions rise, they jump

up and use their hind legs to deliver

powerful kicks to their opponent's

stomach. These intense kickboxing jewels

determine the strongest male, who then

leads the group and passes on his

superior genes to the next generation.

Female kangaroos have a unique

reproductive ability, allowing them to

maintain stable populations even in

changing

environments. They can be continuously

pregnant while raising three offspring

at different stages of development. An

embryo can pause its growth and resume

development only when conditions become

favorable. Meanwhile, the youngest

offspring, Peanut, remains inside the

mother's pouch, nursing and developing

gradually. The older Joey has left the

pouch, but still depends on its mother's

milk until it becomes fully independent.

If environmental conditions become too

harsh, the mother may stop supporting

Peanut to focus her energy on Joey,

ensuring that at least one offspring

survives. Kangaroos have large,

sensitive ears that rotate in multiple

directions, detecting sounds from all

around and helping them sense danger

early. When a dingo appears in the

distance, the kangaroo immediately perks

up its ears, assessing the situation. If

chased, it accelerates and leaps

forward, leaving its predator behind

with speed and quick directional

changes. When cornered, kangaroos use a

powerful defense tactic. They stand

upright, lean on their strong tail, and

deliver a devastating kick with their

hind legs, strong enough to break

[Music]

bones. Beneath the Earth's surface,

another world exists. As rainwater seeps

through limestone layers, it reacts with

carbon dioxide in the air, forming a

mild acid that gradually dissolves the

rock, expanding cracks and creating

underground

caves. Under the dim glow of torches,

massive stelactites hang from the cave

ceilings. Meanwhile, stellagmites rise

from the cave floor, shaping a mystical

landscape where the passage of time is

recorded in layers of

sediment. The limestone cave systems of

the grasslands and savas are ideal

destinations for nature and geology

enthusiasts.

Guided cave exploration tours offer the

chance to step into a world completely

different from the landscape

above. Pathways inside the caves lead

visitors through limestone corridors

formed over millions of years where

beams of light filtering through ceiling

cracks cast shimmering reflections on

the stelactites.

Even the smallest sound echoes through

the vast space, creating an atmosphere

that is both mysterious and awe

inspiring. As visitors pass through

narrow passageways leading to natural

sink holes, they can fully appreciate

the grandeur of nature where water and

stone have sculpted timeless

masterpieces.

[Music]

the hot dry winds carry golden sands

across the glowing red dunes of the

Great Victoria Desert, vanishing into

the endless horizon.

[Music]

Covering more than 35% of the continent,

Australia's desert ecosystem stretches

from the barren rock fields of the

Gibson Desert to the vast sand plains of

the Simpson Desert. But Australia's

deserts are not lifeless wastelands. On

the contrary, they are among the

harshest yet most biologically diverse

environments on Earth.

Desert plants have evolved deep root

systems extending meters into the ground

to access underground water. Some

species have transformed their leaves

into spines, minimizing water loss while

also deterring herbivores. Animals, too,

have evolved remarkable adaptations to

survive in these extreme conditions.

The Simpson Desert spans an area of

approximately

176,500 km. Located between Queensland,

the Northern Territory, and South

Australia, it is one of the largest sand

deserts on the continent. This is one of

the harshest landscapes where summer

temperatures can soar up to 50° C and

annual rainfall is scarce, measuring

less than 150 mm. The dunes here are

grand natural sculptures, some

stretching over 500 km, shaped by the

wind into parallel ridges that have

remained for centuries. The color of the

sand shifts with the sunlight, appearing

pale gold in the morning and deepening

to crimson red at sunset. Each dune

serves as a natural barrier, dividing

the desert into isolated ecological

zones where animals hide during the

scorching daytime heat and only emerge

when the temperature cools at

[Music]

night. The thorny devil with its rough

spiky skin is a small reptile averaging

20 cm in length. As it moves across the

desert, it takes jerky, unpredictable

steps, mimicking a windb blown leaf,

making it harder for predators to track

its true direction. Its sand colored

skin allows it to blend almost perfectly

with the dry terrain, minimizing the

risk of being spotted by

[Music]

predators. When threatened, it can

remain completely still, relying on its

camouflaged body to trick potential

attackers. If attacked, the thorny devil

has a final defense, a false head

located on the back of its neck. By

lowering its real head, it hides it

completely, leaving predators to focus

on the harmless spiky decoy, increasing

its chances of

survival. The sharp spines covering its

body are not just physical armor against

predators, but also help reduce water

loss by limiting direct sun exposure.

We often think of lions or tigers as the

most fearsome predators, but in

Australia, a much smaller creature can

take you down even faster. If you

haven't guessed it yet, stay tuned for

more clues. It's a venomous snake, a

swift and precise bite. Its venom

contains a mix of neurotoxins and

procoagulants, causing paralysis within

minutes.

This is the western brown snake, ranked

among the top 10 most venomous snakes in

the

world. However, due to the relatively

low venom injection per bite, fatalities

in humans are

rare. Even so, a single bite can cause

excruciating pain, nausea, internal

bleeding, and organ failure if left

untreated.

Jagged mountain ranges rise from the

earth stretching along the eastern edge

of the continent. Unlike the vast

deserts or endless grasslands,

Australia's highlands and rocky regions

are where stone and forest coexist,

balancing altitude, climate, and

ecosystem dynamics. Early morning mist

veils the peaks. Sheer cliffs stand tall

and icy rivers carve through deep

gorges. Each element telling the story

of a rich yet challenging

ecosystem. Here climate variations are

more pronounced than anywhere else. In

the high altitude regions such as the

Australian Alps, snow blankets the peaks

during winter. Meanwhile, in lower

elevations such as the Grampians or

Flenders ranges, the land endures

prolonged droughts. This stark contrast

creates a diverse landscape of flora and

fauna where each species must adapt to

survive.

[Music]

Southwest of Ka's Queensland on the

Atheertton tablelands, thin clouds drift

lazily across the deep blue sky,

reflecting on the still waters of Crater

Lakes. The history of Athetherton is

written in its rich red bassalt soil,

one of the most fertile in Australia.

Formed by the weathering of volcanic

ash, this region is one of the few

places in Australia capable of

sustaining tropical

rainforests. Towering red cedar, black

bean, and kari pine trees stand proudly,

creating a multi-layered ecosystem that

shelters thousands of animal

species. Athetherton is not just a

wildlife haven, but also a perfect

destination for nature enthusiasts.

Forest trails like Misty Mountains

walking tracks lead visitors through

hidden waterfalls, sheer cliffs, and

untouched ancient

forests. One of the most unforgettable

experiences here is swimming in a crater

lake where the calm, crystalclear waters

make you feel as if you are drifting

through a prehistoric world.

[Music]

In the shade of the forest, sounds echo

from every direction. The bower bird

with its iridescent feathers and

intricate courtship rituals dances among

the branches. Rare tree kangaroos

adapted to aroreal life gracefully climb

through the canopy, keeping their

distance from ground dwelling predators.

[Music]

For nocturnal creatures like the lesser

Suty owl, this forest is a vast

labyrinth where they silently hunt

insects hiding in the leaf

litter. On the forest floor, clear

streams wind between mosscovered rocks,

cascading down into gentle waterfalls

before merging into crater lakes.

Lake Ekim and Lake Bahin, two of the

most famous crater lakes in the region,

were formed by volcanic eruptions tens

of thousands of years ago. Their emerald

waters reflecting the sky and dense

rainforest canopy create a pristine and

mesmerizing landscape. Native fish such

as the baramundi glide through the deep

waters while tropical butterflies

flutter above, adding vibrant splashes

of color to the

ecosystem. For those who wish to

experience nature in comfort, eco

retreats like Chambers Wildlife

Rainforest Lodges offer accommodation

nestled within the forest. Here, every

morning begins with the songs of birds

echoing through the towering trees,

creating an unparalleled connection with

[Music]

[Applause]

nature. In northern Queensland, towering

black boulders stack upon one another,

forming a giant labyrinth of rock

beneath the vast blue sky. Black

Mountain, known to indigenous

Australians as Kolkajaka, stands like a

natural fortress amid the untamed

plains. Enormous rounded granite

formations, some the size of entire

houses, lay scattered as if chaotically

tossed by a raging storm.

Between 259 and 252 million years ago,

magma from deep within the earth cooled

and crystallized, forming trathan

granodorite, a unique type of granite.

Over millions of years, erosion wore

away the upper layers, revealing these

massive pale gray boulders. But when

exposed to air and moisture, a thin

layer of blue green algae gradually

coated their surfaces, transforming

Black Mountain into a dark and enigmatic

monolith against the tropical

landscape. Natural cracks and crevices

between the rocks have given rise to an

extensive underground cave system where

light barely

penetrates. Within these shadowy depths,

an isolated ecosystem thrives, almost

completely cut off from the outside

world. Rare endemic species found

nowhere else on Earth, have adapted

perfectly to the perpetual darkness.

Among them, the yaka skink stands out.

One of the rarest lizards in the world,

restricted to just a six square km range

around Black Mountain. Despite its

majestic beauty, Black Mountain is not

easily explored. Its treacherous terrain

with deep hidden crevices between the

scorching hot boulders making navigation

extremely

challenging. Those who attempt to

conquer this mystical place must endure

rugged paths where the sunbaked black

stones can reach blistering temperatures

under Queensland's relentless heat.

Leaving behind Australia's highlands and

Rocky Mountains, the sunlight pierces

through the dense canopy of the tropical

[Music]

rainforests. Torrential rains drench the

fertile soil beneath. The air is thick

with humidity, heavy with the scent of

moss and decaying leaves. In the serene

stillness broken only by the calls of

birds and the buzzing chorus of insects,

Australia's rainforests stand as a realm

of their own, a world unlike any other

on the

[Music]

continent. Spanning

1,200 km, Daintry is Australia's largest

tropical rainforest. It is also the

oldest surviving rainforest on Earth

with a history dating back over 180

million years, making it even older than

the Amazon in South

[Music]

America. Although these forests cover

only a small fraction of the continent,

they are home to over half of

Australia's bird species, 60% of its

butterflies, and 65% of its ferns.

Inside the rainforest, life thrives in

every

[Music]

corner. Towering trees like the

Antarctic beach stretch toward the sky,

having endured dramatic geological

changes since the Gonduana era. Their

expansive branches form a thick canopy,

trapping moisture and maintaining a

stable climate for the countless plants

and animals below. More than 2,800 plant

species have been identified in Daintry,

including ancient species rarely seen in

the modern

world. For the Cuku Yalangji people, the

rainforest is deeply intertwined with

spirituality and cultural identity.

Legends passed down through generations

tell of the forest's creation and the

guardian spirits that protect its rivers

and trees. Today, cultural tours offer a

unique opportunity to learn from the

cuckoo yalangji, exploring how they use

plants for medicine and track wildlife

through the

[Music]

forest. Beneath the crystalclear waters

of the rainforest, one of the world's

most bizarre creatures glides

effortlessly. The platypus, a unique

evolutionary marvel, stands as one of

nature's strangest creations.

Though it is a mammal, the platypus lays

eggs instead of giving birth to live

young, a trait found only in the

monotrems, a group that also includes

the ashidna. Its body is a fusion of

multiple species, a duck-like bill,

webbed feet like an otter, waterproof

fur, and a venomous spur on the hind

legs of males. When scientists first

discovered a platypus specimen in the

late 18th century, they believed it was

a hoax. But in reality, the platypus is

one of the most perfectly adapted

amphibious

[Music]

mammals. If the platypus is one of the

strangest mammals, then the southern

casawary is equally a remarkable bird.

Standing up to 1.8 8 m tall and weighing

around 60 kg. It is Australia's largest

flightless bird. A direct descendant of

ancient birds that once roamed the earth

alongside dinosaurs. Its most

distinctive feature is the helmet-like

cask, a bony crest protruding from the

top of its head. This cask plays a

crucial role in regulating body

temperature, helping the casawary

dissipate heat as it moves through the

hot, humid rainforests.

Due to its massive size, the southern

casawaryi has no real natural predators.

A single kick from its powerful legs can

cause severe injuries. With a strike

force of up to 600 kg, its kicks are

strong enough to break bones and

incapacitate any

threat. Its middle toe is armed with a

12 cm long razor-sharp claw, making it a

formidable weapon when cornered.

However, rather than seeking conflict,

casawaries prefer to avoid confrontation

using the dense undergrowth to disappear

into the forest. The breeding behavior

of the southern casawary is particularly

unusual. After laying 3 to five eggs,

the female leaves, abandoning the

incubation and rearing duties to the

male.

[Music]

For 50 days, the male casawary

diligently keeps the eggs warm using its

body, rarely leaving the nest and barely

eating. Once the chicks hatch, the male

continues to protect them for 9 months,

teaching them survival skills and how to

forage for food in the rainforest. When

they reach independence, the young

casawaries embark on a solitary journey

through the tropical ecosystem.

[Music]

As an omnivore with a diet dominated by

fruit, the casawaryi consumes over 150

different plant species, ranging from

soft, easily digestible fruits to large,

thick-skinned varieties that most

animals cannot process. Seeds are

swallowed whole, passing through its

digestive system before being dispersed

through its droppings, helping to

repopulate the forest with new plant

life. Some tree species rely entirely on

the casawary to disperse their seeds,

making it a crucial gardener in the

tropical

ecosystem. Despite being an icon of the

daintry tropical rainforest, southern

casawary populations are in steep

decline. Deforestation and urban

expansion have significantly reduced

their habitat, placing the species under

increasing pressure. Additionally, many

individuals fall victim to vehicle

collisions while attempting to cross

roads, while others fall prey to illegal

hunting. Currently, the southern

casawary is classified as endangered

with fewer than 2,500 individuals left

in the wild.

Slowmoving clouds drift across the deep

blue sky, casting a misty veil over the

rolling mountains of the border ranges,

where the tropical rainforests of

southeastern Queensland extend to the

New South Wales border.

This rainforest is not only an

ecological treasure but also a

geological relic holding the marks of

millions of years of earthshaping

events. Around 20 million years ago, a

massive volcanic eruption reshaped the

landscape, leaving behind a rugged

terrain of sheer cliffs and deep basins

where underground streams still weave

through layers of earth.

Winding forest trails offer an immersive

ecoourism experience, allowing visitors

to connect with nature's untouched

rhythms.

The Maria boardwalk leads through dense

rainforest where ancient Antarctic beach

trees stand tall alongside primitive

ferns that date back to the dinosaur

era. Some of these trees have endured

for over 2,000 years, acting as silent

witnesses to the time of the superc

contininent Gonduana when Australia was

still connected to South America and

Antarctica.

In the higher elevations, viewpoints

like Best of All Lookout reveal

breathtaking panoramic views of the

valleys below, where rainforests merge

with grasslands and natural

lakes. Dawn casts a misty veil over the

dense canopy of Queensland's border

rainforests. The calls of birds echo,

blending with the steady hum of insects

filling the forest with the morning

chorus of life. Through this scene, a

tall, powerful figure strides across the

soft earth, the emu. It is Australia's

largest running bird, reaching 1.9 m in

height and weighing between 40 and 50

kg. As the breeding season arrives in

the later months of the year, female

emus seek out mates.

[Music]

Like the southern casawaryi, male emus

take on the primary responsibility for

the next generation. For 8 weeks, the

male remains on the nest, shielding the

eggs from predators and environmental

threats. During this time, it does not

eat, surviving only on dew collected

from leaves to maintain energy.

When the chicks hatch, they emerge as

tiny striped fledglings covered in brown

and black down. They stay close to their

father, learning how to forage for food

and avoid the dangers lurking in the

forest shadows. The emu's diet is highly

varied, consisting of seeds, fruits,

young leaves, and small insects.

Its powerful digestive system allows it

to process a wide range of plant matter,

enabling it to thrive in humid forests

as well as dry

grasslands. Beyond being just a forager,

the emu plays a vital role in the

ecosystem by dispersing seeds through

its droppings, allowing many plant

species to spread and flourish. Its long

strides carry seeds far beyond their

original location, contributing to the

biodiversity and regeneration of the

tropical

[Music]

rainforest. Not just a land of dry

deserts, vast grasslands, and dense

forests, Australia is also home to

expansive wetlands stretching to the

horizon. The wetlands of Australia are

among the continent's most vital

ecosystems. Here, water is never static,

shifting with the seasons rising and

retreating, creating a dynamic cycle

that supports thousands of species

dependent on its eb and flow.

Kacadoo National Park, Australia's most

famous wetland, is a prime example of

the biological diversity of these

ecosystems. Spanning

19,84 km, it is larger than some

countries. During the wet season,

torrential monsunal rains flood the

region, filling the east alligator,

south alligator, west alligator, and

wildman rivers, transforming the

landscape into a vast interconnected

ecosystem teameming with wildlife. As

the dry season approaches and the waters

recede, the remaining water holes become

biodiversity hotspots where hundreds of

birds, reptiles, and mammals gather to

compete for precious resources.

[Music]

Lotus liies bloom on the calm waters

surface. Their soft pink petals rising

from the muddy depths reflecting the

golden sunlight. Beneath them, thousands

of insects, amphibians, and freshwater

fish thrive in the swamps, forming the

base of the food chain for larger

predators. On the banks, saltwater

crocodiles, the largest reptiles on

Earth, lie motionless, waiting for the

perfect moment to strike. They have

roamed these waters for millions of

years, reigning as apex predators of the

wetlands.

[Music]

Kakadoo is not only a haven for

reptiles, but also a sanctuary for over

280 bird

species. The Jabiru, Australia's largest

stalk, with its 2 m wingspan, soarses

over the shallow waters. Magpie geese

gather in large flocks, their loud calls

echoing across the flooded plains. At

sunset, the Brolar, the iconic crane of

the Northern Territory, begins its

graceful courtship dance, a mesmerizing

spectacle in the heart of the

wild. During the dry season, as water

levels drop, the majestic waterfalls of

Jim Jim Falls and Twin Falls reveal

their towering limestone cliffs carved

by centuries of relentless water flow.

The cool plunge pools below offer the

perfect retreat to unwind after days of

exploring the untamed

[Music]

wilderness. As an isolated continent,

Australia is home to a rich and diverse

marine ecosystem with a coastline

stretching over 34,000 km and an

exclusive economic zone covering nearly

8 million km.

This vast marine territory extends from

the cold southern waters where the

southern ocean meets the Tasmanian

coast. It is home to tens of thousands

of marine species, many of which are

found nowhere else on Earth. Powerful

ocean currents such as the East

Australian current transport warm

tropical waters southward, creating a

migration corridor for a wide range of

fish, marine mammals, and seabirds. The

Great Barrier Reef, the largest coral

reef system on Earth, stretches over

2,300 km along the Queensland coastline,

standing as one of the greatest natural

wonders ever shaped by our planet.

Covering more than

344,400 km, this vast ecosystem is home

to thousands of marine species thriving

among the vibrant hues of 400 coral

species in a dazzling array of shapes

and sizes. Visiting the Great Barrier

Reef offers unforgettable underwater

adventures.

Scuba diving takes explorers into the

depths of the reef where they can come

face to face with majestic manta rays

gliding effortlessly through the

currents. In the shallower waters,

snorkeling provides the perfect way to

drift along and observe colorful fish

schools weaving through the coral

gardens. Some areas even allow swimming

alongside blacktip reef sharks, a small

and gentle shark species commonly found

near the reef.

[Music]

But beyond the blacktip reef shark, the

sunlit waters of the great barrier reef

conceal a wild and intricate world of

highly skilled

predators. Lying motionless among the

coral outcrops, the spotted wobberong is

a master of camouflage. Its patented

body mimics the seafloor, making it

nearly invisible as it ambushes

unsuspecting prey.

When a small fish or crustation drifts

too close, it strikes in an instant,

opening its jaws wide to swallow its

victim in a single snap. Can a shark

really sense the heartbeat of its prey

from hundreds of meters away? That might

be true for the great white shark, a

long-d distanceance predator that

migrates up to 10,000 km per year. They

are apex hunters using speed and power

to take down large prey like seals and

sizable fish. Yet, despite their

fearsome reputation, sharks are not

man-eaters. Most shark attacks on humans

occur due to mistaken identity as a

surfer or swimmer may resemble their

natural prey. Globally, shark related

fatalities range from 5 to 15 per year.

Since 2000, the great white shark has

been confirmed in 18 fatal incidents,

while the bull shark and tiger shark

have each been responsible for only one

recorded fatality. Though often labeled

as the killers of the ocean, the odds of

a shark attack are far lower than

everyday hazards like bee stings or

lightning

strikes. During the wet season, from

October to April, Australian box

jellyfish appear in greater numbers,

drifting closer to shore in search of

small fish and plankton. This is one of

the most dangerous creatures on the

planet. The nearly transparent tentacles

of the Australian box jellyfish can

extend up to 3 m, forming an invisible

and deadly web. When they make contact

with prey, millions of venomous cells in

the tentacles fire instantly, delivering

venom. so rapidly that it paralyzes the

victim almost

immediately. For humans, even a small

sting can cause excruciating pain,

cardiac arrest, and death within minutes

if not treated

immediately. The venom from one adult

jellyfish contains enough toxins to kill

60 people. Since 2000, at least 10

fatalities caused by Australian box

jellyfish have been recorded in

Australia. When stung, intense pain

spreads instantly and the skin turns

purple red with distinct welt-like marks

along the area of contact. In many

cases, the venom triggers irkji

syndrome, a condition of extreme pain

accompanied by nausea, rapid heart rate,

and the risk of acute heart failure.

[Music]

However, as a predator, the Australian

box jellyfish plays a crucial role in

the Great Barrier Reef ecosystem. They

help control the population of small

fish and plankton, maintaining balance

within the food chain.

[Music]

The surface of the southern ocean of

Australia may appear calm, but beneath

the waves lies a world teeming with

color and movement. Cold currents from

Antarctica carry nutrientrich waters,

fostering the growth of a vibrant and

diverse marine

[Music]

ecosystem. Amidst the swaying kelp

forests, a strange yet mesmerizing

creature drifts effortlessly, nearly

indistinguishable from the delicate

strands of seaweed around it. The leafy

sea dragon, one of the ocean's most

masterful camouflage artists, moves

silently and

unnoticed. Its body is adorned with soft

leaflike appendages resembling tiny

fronds sprouting from every part of its

form.

When it floats among the underwater

greenery, it appears as nothing more

than a wandering piece of drifting

seaweed. This nearperfect disguise

allows it to evade predators like reef

sharks and groupers, which patrol the

waters in search of

[Music]

prey. The leafy sea dragon spends most

of its time drifting, watching for

plankton, mice shrimp, and tiny fish

passing by. When prey comes within

reach, it uses its long tube-like snout

to generate a powerful suction,

instantly inhaling its victim. This

stealthy hunting technique allows it to

remain hidden, maintaining its

camouflage even while feeding.

[Music]

The southern ocean sways gently beneath

the fading light of sunset, reflecting

the last golden rays of the day. Beneath

the cold, deep waters, a giant moves

silently toward the shore.

The southern right whale, one of the

largest whales in the ocean, begins its

annual migration of over 10,000 km,

traveling from the icy waters of

Antarctica to the warmer seas off

Australia's coast. Unlike other whale

species, it lacks a dorsal fin, an

evolutionary adaptation that helps it

conserve energy on long journeys. As it

migrates, it does not swim rapidly, but

glides effortlessly with the currents,

using the gentle movements of its tail

to maintain a steady

pace. From June to October, the coastal

waters of head of the bite and warn

become gathering grounds for mother

whales and their newborn calves.

Newborns measuring about 5.5 m at birth

depend entirely on their mother's

fatrich milk to grow. They consume

hundreds of liters of milk per day,

rapidly gaining weight to build strength

against the many dangers that lie ahead.

This is a season of birth, nurturing,

and survival. A crucial time for a

species that once teetered on the brink

of extinction. Before the 19th century,

southern Wright whales were heavily

hunted for their thick blubber and

highquality oil. The name right whale

comes from whalers who considered them

the right whale to hunt. They were slow

swimmers, floated after death, and

yielded an enormous amount of oil. As a

result, their population plummeted to

critically low levels, nearly vanishing

from the oceans. In recent decades,

conservation efforts have helped this

whale population begin a slow

recovery. The Australian government has

implemented strict monitoring programs,

established marine sanctuaries, and

enforced stronger regulations to

minimize human impact. The latest

national recovery plan released in

2024 marks an important step toward

securing the future of this remarkable

species.

[Music]

The hot winds sweep across Australia,

breathing life into the iconic wildlife

of this land. Yet, these creatures now

face unprecedented environmental

challenges. Every step taken across

Australia's forests, deserts, and reefs

leaves a mark. But will that mark be one

of destruction or

conservation? Research from Griffith

University and the University of

Queensland estimates that 15.6 billion

Australian dollars per year is needed to

save 99 priority species. A steep price.

But what could be more valuable than the

life of the creatures that bear the

unique signature of this

[Music]

land? The forests still stand. The

wildlife still fights to survive. But

time is running out. To protect this

unique ecosystem, the Australian

government has launched the threatened

species action plan, focusing on 110

priority species.

In the next decade, at least 30% of land

and marine areas will be designated for

conservation, expanding protected

regions by 50 million

[Music]

hectares around

224.5 million Australian alien has

already been invested to protect native

species. But research suggests that at

least 15.6 billion Australian dollars

per year is needed to prevent

extinctions. Conservation efforts go

beyond habitat protection. They also

include controlling invasive predators

like feral cats and red foxes, the

primary causes of native species

decline.

[Music]

Koala rescue programs and coral reef

restoration efforts are being

implemented to ensure the future of

Australia's

[Music]

ecosystems. But this is not enough. This

extraordinary nature needs the

collective effort of all. Reduce plastic

waste, support conservation

organizations, respect wildlife

habitats, and spread awareness in your

community. A small action today can make

a big difference for the

[Music]

future. Have you ever seen any of the
