Australien

In the vast, dramatic forests of eastern Australia the cuddly koala is showing a not so cuddly side, while below the canopy some of the continents strangest creatures can be found, from a bird juke-box to a duck-billed mammal that lays eggs - the platypus.

The hostile dry plains of southern Australia are home to extraordinary plants and animals that have adapted to the heat, from colourful parrots to deadly ants, dangerous dingoes to killer bunnies and of course the specialist of the plains, the lovable wombat.

Impenetrable rainforest revealing kangaroos who live in trees and a colossal bird with dinosaur feet - the Australian tropics are the most mysterious part of the fifth continent.

Their kingdom is the desert: in the heart of Australia lives the largest marsupial on earth, the red kangaroo - a true master of adaption in a world full of natural wonders and extremes.
