Australia: a land cast adrift at the time of the dinosaurs.
Isolated for millions of years, the weird and wonderful animals marooned here are like nowhere else on Earth. In its jungles a cassowary - one of the most dangerous birds in the world - stands six feet tall.
Inland, kangaroos and wombats brave snowstorms, and gum tree forests are filled with never-before-seen predators. In its red desert heart, reptiles drink through their skin and huge flocks of wild budgerigars swirl in search of water. On secret islands Tasmanian devils roam, and offshore thousands of sharks gather for a rare event.
