Continuing his three-part adventure roaming the islands of the antipodes, Martin Clunes is in Australia’s northern and western regions to take in some of its most remote islands.

He begins in the tropical north with a trip to the Tiwis – also known as the ‘Islands of Smiles’ – where he joins a foraging trip whose spoils include a much-prized mud whelk called the ‘longbum’!

Martin also goes diving on a visit to the Muiron Islands, encountering a dazzling array of wildlife including the endangered whale shark, and learns about the dark past of tourist hotspot Rottnest, once home to a prison for Aboriginal people.
