Coast has arrived in Australia for its biggest expedition ever. After almost a decade exploring the coastline of Britain and Europe, historian and archaeologist Neil Oliver is leading a local team of presenters to discover Australia's spectacular coastline: its people, their history and its many natural wonders.

On Australia's shiny holiday coast, Miriam Corowa investigates the engineering behind the 1970s Florida-style canal system of the Gold Coast. Brendan Moar dives headlong into a dangerous current to investigate first-hand the science of rips. Xanthe Mallett scours a World War II fortification at what could have been Australia's front line, and discovers what life was like waiting for the war to arrive.

Neil Oliver heads to see the remains of a bleak chapter in history - an outpost for outcasts. Emma Johnston joins a scientific hunt for sea cows, in the hope of saving them. Finally, Tim Flannery travels to Fraser Island to investigate what's at the end of the line for the longest sand drift system in the world. Show less
