Intrepid host Greg Grainger journeys to the most dangerous corners of Australia in the first installment of his nature adventure series, which finds Grainger in the aptly named Snowy Mountains and at the wilderness of Kakadu. Highlights include a group of aborigines on the hunt for wild outback snakes while hungry crocodiles swarm in all directions. These crocodiles, needless to say, are among nature's deadliest predators.
