Nature's Microworlds - Season 1 Episode 12 Australia's Red Centre

In Australia's red centre, Steve Backshall reveals two-metre-tall kangaroos, the world's most venomous snake and a burrowing toad living among the throng of animals. Parched by the sun, scorched by fire and prone to unpredictable floods, the heart of this island continent is as inhospitable as it gets. Poor soils make vegetation tough and indigestible even to Australia's largest herbivore, the red kangaroo. However, it teems with animals found nowhere else on Earth. The key to the success of this extraordinary place is as surprising as the creatures that make it home.
