Australia

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 the north of this island continent is the Daintree, one of the world's oldest tropical forests. It's home to the most dangerous bird on earth - the cassowary. A dinosaur-like bird standing six feet tall, they are formidable but their success is down to how well a father cassowary can carefully protect his tiny stripy chicks. Inland, the continent is full of more surprises. The wombat, a tough short-legged marsupial, roams Australia's mountain ranges surviving freezing snowstorms. In the hot gum tree forests is a newly discovered predator with a bizarre courtship ritual, and on the wide, open grasslands the dingo, Australia's elusive and much persecuted wild dog, hunts kangaroos to provide food for its pups. Chases can cover many miles and are often unsuccessful.
