Secrets of Wild Australia: Series 1

In a land as wild and diverse as Australia, it's no surprise that the snakes who live there are among the most dangerous on Earth. Venture into the domain of these spine-tingling serpents and meet venomous vipers with enough toxin to kill 100 people, constricting scrub pythons 28 feet in length, and more.

The Australian dingo might look like a family dog, but with 180-degree vision and a keen sense of smell up to 100 times better than our own, it's an apex predator of stunning efficiency. Explore the world of this much-maligned outback dweller and the complex social code of the pack that governs it.

Saltwater crocodiles, known in their native northern Australia as 'salties,' are highly efficient killing machines. The strongest jaw bite of any living creature and an unusual brain adaptation that literally allows them to sleep with one eye open are just a few of their incredible adaptations. Wade into the tropical wetlands of these prehistoric hyper-carnivores and witness their savagery at close range.

High up in the treetops, along the eastern coastal belt of Australia, lives a special kind of fruit-eating bat: the flying fox. These highly sociable and adaptable mammals live in large colonies numbering in the thousands, wingtip to wingtip. Get a close-up of one of Australia's more unusual and misunderstood mammals.

Thousands of years ago, before the world divided into continents, a group of mouse-like creatures migrated from what is now South America to Australia. Discover two lesser-known, but no less fascinating, members of the extraordinary marsupials: the gentle quokkas and the tenacious quolls.

In Queensland, Australia, rainforests are the perfect incubators for a dazzling variety of insects. From the 240 species of butterfly to the skillful weaver ants that build nests using larval silk, follow the members of a miniature world that rivals the diversity and intricacy of our own.

The tropical north of Australia is a haven of biodiversity, where an exotic array of wildlife shape their lives round the rainy season. Flamboyant jabiru storks, ferocious freshwater crocodiles, and archer fish with astounding marksmanship all play their part in the interconnected life of this ecosystem.
