The red kangaroo is iconic, but as Aaron Pedersen explains there is more to the kangaroo family than just one famous face. Explore how these marsupials spread across the continent, taking on a variety of shapes and forms.

Parrots are by far some of the world's most intelligent birds. Aaron Pedersen explores why these intelligent birds thrive in Australia, and what kind of impact their exceptional intellect has on our environment.

Echidnas and platypuses are unique - the only mammals in the world to share some key traits with reptiles, including laying eggs. Aaron Pedersen explains how they are actually highly-tuned to their environment.

Known as the bulldozers of the bush, wombats are Australia's largest burrowing animals. Aaron Pedersen explores how their digging has transformed landscapes and changed the face of the continent.

There's more to Australia's reptiles than being cold-blooded killers. Aaron Pedersen explores intimate mating rituals and protective mothers and how we're only starting to scratch beneath the scales of our reptiles.

Orcas are notorious for being merciless ocean killers, but as Aaron Pedersen explains, this is mostly a misunderstanding of what is one of Earth's most intelligent mammals, who live together in complex family groups.

The Indian Ocean may be the smallest of the oceans, but it is the most complex. Aaron Pedersen explores how it is home to thousands of diverse species and has a major impact on Australia's climate.

The Pacific Ocean occupies a third of the globe's surface. Aaron Pedersen explores the astounding diversity of this ocean from its depths to its surface, its temperate waters and equatorial regions.

The Southern Ocean is the only ocean that stretches unbroken around the globe. Aaron Pedersen examines how the cold southernmost waters, reaching from Australia to encircle the Antarctic, are rich and productive.

Australia might be world famous for its outback and red deserts, but there are also lush alpine regions that are just as unique and breathtaking and play a central role to the animals living along the east coast.

A year in the life of Kakadu in Australia's Top End. Aaron Pedersen explains the six seasons recognised by the Bininj people and reveals the web of relationships between its species and the environment.

The magnificent rock that is Uluru is an icon of Australia - remote, untamed, and mysterious. However, as Aaron Pedersen explains, the Red Centre with its arid deserts hold much more than meets the eye.

The Daintree Rainforest has one of the highest rates of biodiversity on Earth. Aaron Pedersen explains how this oldest rainforest on Earth is a window into an Australia that has otherwise vanished.

Extending over 2000km, the Great Barrier Reef is a complex system. Aaron Pedersen explains that its beauty is just one of many amazing features that makes this natural wonder so important.

Tasmania is a world lost in time, an isolated pocket of Gondwana-era forests and Jurassic mountains sheltering animals that live nowhere else on the planet. Even in its isolation, the island is under threat.

Wetlands are a critical part of our natural environment. They protect our shores from wave action, reduce the impacts of floods, absorb pollutants and improve water quality.

Australia is the driest inhabited continent on earth, with seventy percent of the land mass declared an arid zone. Spanning five million square kilometres, this zone is one of the most exposed areas on the planet.

Australia is an island continent boasting nearly 35,000 kilometres of coastline. Humans come to the seaside to relax, but for tens of thousands of species that live and breed on our coast, it's a battleground.

While forests only cover only 16% of Australia's land area, they harbour a higher concentration of animal species than anywhere else on the continent.

The narrow strait between the Indonesian islands of Bali and Lombok marks the boundary between the wild worlds of Asia and Australia. This is the story of life on each side of nature's great divide.

The Wallace Line divides separate worlds, where radically different animals live remarkably similar lives. This is the story of two parallel creations, and what happens when these worlds collide.

Safe behind the Wallace Line, life in Australia charted its own evolutionary course, in habitats defined by natural borders. This is the story of the wild kingdoms protected by Nature's Great Divide.

Cyclones burst upon Australia's tropical coast bringing torrential rain and destruction, while ancient rain forests and coral reefs are destroyed. Aaron Pedersen explains how these ecosystems have evolved and adapted.

Australia is the driest inhabited continent on earth, and severe droughts grip the nation regularly. Aaron Pedersen explains how over millions of years of evolution, Australian life is uniquely prepared for these challenges.

Blazes fuelled by wind, dry bush and weather can consume everything in their path. Aaron Pedersen explains how nowhere on Earth burns with quite the same intensity and ferocity as Australia - or as regularly.

Australian droughts are often followed by flood, a rhythm of life that the country has adapted to. While the inland is still subjected to natural floods, elsewhere the flood regimes are changing.
