Steve, Terri and Bindi set out on their luxury cruiser, 'True North', to navigate the rugged coast of Western Australia. The first island they visit is home to hundreds of highly venomous tiger snakes, while Steve and Bindi have the enviable experience of swimming with a pod of wild dolphins. When the sonar reveals a large school of hammerhead and silver-tip sharks, Steve gets the chance to try his luck hand-feeding them. A close encounter with a humpback whale and her calf provides some of the most amazing whale vision ever seen! Finally, Steve has the ultimate experience of swimming with the largest fish in the world - the whale shark!
