Martin begins the final part of his journey on Mundoo Island. Located in the mouth of Australia's longest river, the Murray, it is an island farm. Its unique combination of succulent saltmarsh plants and life-giving fresh water make it ideal for beef cattle. Mundoo Island has provided shelter and a way of life for five generations of one farming family.
Martin travels to the heart of the tropical north to the Tiwi Islands. More than 3000 Tiwis live on the islands and, thanks to their isolation from the mainland, they have kept many ancient traditions alive. Next, he swims amongst the vividly colorful coral gardens when he visits Ningaloo Reef in Western Australia, before heading back to the mainland to swim with a whale shark.
Martin's first stop is Lord Howe Island, where he experiences life in a remote island community and encounters several species of flora and fauna that occur nowhere else on Earth. He then arrives in Norfolk Island in time for the annual Foundation Day ceremony, before moving on to Restoration Island where he meets a modern-day Robinson Crusoe.
