278km via Nundroo, Nullarbor to Bunda Cliffs free bush camp (-31.584062,130.390864) We topped up on fuel at $1.41. We continued on the A1 …past a couple of road signs and road trains..It is also where the Eastern end of the Nullarbor (the treeless plain) begins. This area was once part of the ocean floor and is the world’s biggest, flattest piece of limestone, covering an area of 200,000 square kilometres and is up to 300m thick! The Nullarbor Roadhouse is a popular stop with its old roadhouse. We took the opportunity to get clean with the $1/5mins showers!
