The Nullarbor

The Nullarbor Plain covers some 200,000 km2 and consists of sedimentary limestone laid down between 6 and 60 million years ago in a vast, shallow, sea bed. The rock is highly fossiliferous and the region is classified as arid ? with an average annual rainfall of less that 250mm, though localised deluges often exceed that.
