Deep Dive...

Explore the shores of the Northern Territory and the abundant waters of the Great Barrier Reef, facing flooded roads, hungry saltwater crocs and killer jellyfish.

Say goodbye to the tropics and dip into cool southern-coast waters, coming face to face with majestic grey nurse sharks, shape-shifting cuttlefish and huge blue whales.

The trip's final lap visits the land where Australia's desert meets the hostile Indian Ocean. Confront the challenges of survival as Lizzie dives with tiger sharks and manta rays.
