Travel with Penny and the DiscoverOz crew to the Top of Down Under. Starting in Cairns and travelling all the way to the highest point of the Cape York Peninsula, jump on board for a white knuckle ride, from fishing, gold fossicking and snake wrangling, to crossing croc infested creeks. Pitting driver and vehicle (as well as a couple of trailers) against some of Australia's most challenging terrain, re-live one of the ultimate 4WD experiences in the extremely popular and challenging Cape York.
