Kayne soon discovers that riding a remote-control skateboard in the South Australian bush is the easiest part of his first mission as Brandon has set him a nerve-racking challenge - to go diving with Great White sharks! And as sharks are attracted to noise, Kayne has to beat box while under water to lure one in. Will Kayne complete the mission or will he chicken out? Plus the boys meet shark attack survivor, Rodney Fox, a Barngaria Aboriginal elder and get up close and personal with kangaroos, emus and sea lions.
