The Nullarbor Plain (/ˈnʌlərbɔːr/ NUL-ər-bor; Latin: nullus, "no", and arbor, "tree") 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 kilometres (684 mi) from east to west across the border between South Australia and Western Australia.
National Park[]
Nullarbor National Park preserves rare vegetation and fauna. The plain has many limestone caves, including Koonalda Cave, an important archaeological site. There are, on the plain, scattered sheep stations along the margins, supplied by artesian water.[1]
Koonalda Cave is of great importance to the history of Aboriginal occupation and is of particular significance for the Mirning people. The cave contains exceptionally well preserved markings by Aboriginal people. It is the first site identified in Australia that has Aboriginal ‘art’ in an area beyond the reach of natural light.[2]
