Queensland's Cape York is one of the last wild frontiers in Australia. Steve and Terri set out on a journey along some of the most treacherous roads and remote rivers to reach the very northern-most tip of the country. Along the way they encounter a huge array of wildlife including a slately grey snake, an angry scrub python, a rusty monitor goanna, feral pigs and a tree-jumping canopy goanna - the rarest goanna species in the world.
