Stretching over 200,000 square kilometres across southern Australia, the vast, flat plains of the Nullarbor mark one of the world’s largest regions of limestone. It formed when an ancient shallow sea retreated some 14 million years ago.
Ultimately, this led to the familiar dry landscape of today, which has acted as a significant barrier for plants, animals, and poorly adapted colonial Victorian-era explorers who described it as “the sort of place one gets into in bad dreams”.
