Tension fills the air as the team's waterlogged cargo boat begins to sink; they are on their way to Borneo to help with a UNICEF vaccination project. With the boat out of action, they have to find another way. Three hundred miles of lush rainforest later, Charley and the UNICEF team arrive with the vaccines in a village up the Pawan River, deep in the heart of Kalimantan on Borneo. Having missed the one ferry that would take them to Bali, the team have no choice but to double back and fly to their destination. From Bali, Charley embarks upon a series of boat journeys navigating his way across the Indonesian archipelago. From speedboats to hand-built traditional phinisi boats and hugely overcrowded ferries, he makes his way to Kupang. After a turbulent five-day crossing from Kupang aboard a handmade boat, Charley and the team are delighted to finally hit the shores of Australia - the end of the journey is in sight! However, it is not enough to be on the right continent - there is still a huge distance to cover across the outback. The team decide to take the most direct route to Sydney over the Snowy Mountains, but are thwarted by bad weather. Charley tests all sorts of weird and wonderful forms of transport from campervans to camels and road graders to road trains. On the last leg into Sydney, Charley leads an epic biker convoy over the famous Sydney Harbour Bridge. The trip that started life on the back of a boarding pass, that charted a journey from Ireland to Sydney using over a 100 means of transport in 102 days, is complete.
