South of Kalgoorlie the Great Eastern Highway runs 190km to Norseman, at the western end of the Eyre Highway. The highway is named after the explorer Edward John Eyre, who crossed the southern edge of the continent in 1841, a gruelling eight-month trek that would have cost him his life but for the Aborigines who helped him locate water. Eyre crawled into Albany on his last legs but set the route for future crossings, the telegraph lines and the highway.
If you’re heading east on the Eyre Highway from Norseman, it’s about 700km to the South Australian border and another 470km from there to Ceduna. This is the legendary Nullarbor Plain, where a flat, arid and famously monotonous landscape stretches away from the road on both sides, with barely a tree to break it up (nullarbor means “no trees” in Latin). Once this comes to an end at Ceduna, there is still a featureless 775km before you reach Adelaide.
Although the longest stretch without fuel is only 200km, do not underestimate the rigours of the journey on your vehicle. Carry reserves of fuel and water, take rests every few hours and don’t drive at dawn or dusk when kangaroos are crossing the road to feed. There’s a quarantine checkpoint at the border where a large range of prohibited animal and vegetable goods (mainly fruit and veg) must be discarded.
