The Nullarbor Plain is the world’s largest single piece of limestone, covering an area of some 200,000 square kilometres and crossing it is mind-bendingly dull. That being said, there are a few very worthwhile viewpoints along the southern side of the road, where the arid landscape ends rather suddenly at the Great Australian Bight – there is nothing between here and Antarctica.
Facilities along here are limited. BALLADONIA, 191km east of Norseman, has the Balladonia Hotel Motel. Some 246km of virtually dead-straight road further along, you reach COCKLEBIDDY, which has a motel, while MADURA, 83km east, is halfway between Perth and Adelaide (if you’re still counting), and has rooms and caravan sites. MUNDRABILLA, 115km further on, also has a motel and caravan/campsite.
