The Nullarbor Plain is part of the area of flat, almost treeless, arid or semi-arid country of southern Australia, located on the Great Australian Bight coast with the Great Victoria Desert to its north. It is the world’s largest single exposure of limestone bedrock, and occupies an area of about 200,000 square kilometres (77,000 sq mi). At its widest point, it stretches about 1,100 Kms (684 mi) from east to west across the border between South Australia and Western Australia.
The railway line that crosses the Plain has the longest straight section of railway in the world (478 km, 297 mi), while the road contains the longest straight section of tarred road in Australia (146.6 km, 91.1 mi).
The distance across the Plain from Norseman in Western Australia to Ceduna in South Australia is 1,200 Kms and we take 4 days to make it across. We pass several sections of the road which have a dual purpose by acting as emergency airstrips for the Royal Flying Doctor Service.
Our in-car GPS didn’t speak to us for 3 days. Then we realised that she had told us to turn right after 729 Kms yesterday !!
