In Sturt National Park, a network of roads and tracks is maintained by the NPWS to 2WD standard, but check with the rangers at Tibooburra before setting out.
The park’s 3500 square kilometres are cut in two by the Grey Range: to the west are the rolling red sand dunes of the Strzelecki Desert, and to the east the stone-covered, so-called gibber plains extending for hundreds of kilometres. The area supports a number of red and grey kangaroos, emus and lizards.
At the edge of the park, the border between Queensland, New South Wales and South Australia is delineated by the 1.8-metre-high Dingo Fence. This, the world’s longest fence (4850km), was originally constructed by the Queensland government to stop the invasion of rabbits from the south; it’s now maintained to keep dingoes out of sheep-grazing land.
The point where the three states meet is known as Cameron’s Corner and is marked by a post: it’s a popular target for travellers, so much so that there’s even a shop here, the wittily named Corner Store (tel 08/8091 3872). As well as dishing up the ubiquitous meat pies and other typical Aussie fillers, they have fuel and can give you useful road advice.
