SAS: Who Dares Wins chief instructor Anthony Middleton is in charge of a crew of eight made up of sailors and complete novices, attempting the journey in a replica 23ft open wooden boat, with similar equipment and the same rations of food and water that Bligh's men had. ISLANDS VISITED ON THE VOYAGE Start: Tonga Yadua (Fiji) Gaua (Vanuatu) Restoration Island (Australia) Sunday Island (Australia) Albany Island (Australia) Finish: Timor

The men set out to explore a tropical island where they hunt for vital food and water. As they prepare to set sail on the next lego of their voyage, pressures of hunger and the intensity of life on such a small boat start setting in.

Alone in their tiny wooden boat, the eight remaining men face the most challenging leg of their journey so far: 1600 miles across the treacherous Coral Sea.

After two weeks with no sight of land, the remaining men must find a way through the Great Barrier Reef. If they get it wrong, this vast wall of coral could rip out the bottom of their tiny wooden boat.

The crew load up their barrels and kit bags for the last time and set off in the blistering heat of Northern Australia to make the 1200-mile voyage to Timor.
