NULLARBOR, SA TRAVEL
Travelling between Australia's East and West Coasts isn't a journey taken lightly. It's a long way. Much of the trip is remote, and the weather can be harsh. Sydney to Perth is close to 4000km, and the Nullarbor Plain sits pretty much bang in the middle of the trip. The Plain is 1100km at its widest, but the section between the towns of Ceduna in South Australia and Norseman in Western Australia is often eulogised as the actual Nullarbor crossing.
The Nullarbor abuts the Great Victoria Desert and spans more than 200,000 square kilometres, stretching across the border area of South and Western Australia. It's classified as an immature arid limestone karst landscape formed when the area was the sea floor millions of years ago. Karst is a distinctive topography shaped by the weathering of the carbonate bedrock – in this case limestone. Within the limestone surface are numerous caves and sinkholes, some with underground lakes many kilometres long.
A series of uplifts and rising sea levels formed the spectacular Bunda Cliffs along the southern edge of the Plain. The cliffs are the longest in the world and rise to heights over 80m. Their ever-changing hues and breathtaking views are a highlight of a Nullarbor crossing.
