The Nullarbor Plain is the largest single exposure of limestone bedrock
Spanning 200,000 square kilometres in southern Australia, the Nullarbor Plain is almost completely treeless.
The name Nullarbor derives from Latin words meaning no trees. The flat arid plain sits atop an ancient seabed composed of thick limestone layers containing subterranean caves and sinkholes. It features the Indian Pacific railway line, which includes the world's longest straight stretch of railway track at 478 kilometres.
