From the southern coast of Adelaide, all the way to Darwin, the guys take on another road trip - this time with their own purchased 4x4 to get them through the perilous, dusty outback. Fighting constant breakdowns, they reach the underground town of Coober Pedy, where they search for opal with the help of an explosives “expert”. The crew travel from Uluru, staying on a working ranch, before tackling the ultimate offroad adventure through searing sand to remote Boggy Hole. Pushing on through a sudden rainstorm in the north, to the last miles to Darwin, Scott, Justin, and Andre have now travelled to all seven continents. What’s next?
