[[Image:Highway sign, Nullarbor, 2017 (02).jpg|thumb|Sign defining the edge of the plain at the western side. (This photograph depicts Nullarbor Roadhouse, seen from the west. Nullarbor Roadhouse lies on the South Australian side of the Eyre Highway, at the eastern edge of the Nullarbor Plain as well as [[Nullarbor National Park]], which both extend miles farther west into Western Australian territory.)]]
Frequently ''The Nullarbor'' is expanded in tourist literature and web-based material to loosely refer to all the land between [[Adelaide]], [[South Australia]] and [[Perth]], [[Western Australia]]. Through observing satellite images, the limits of the limestone formation of the plain can be seen to stretch from approximately {{Cvt|20|km}} west of the original Balladonia settlement (now abandoned) to its easternmost limit a few kilometres west of the town of Ceduna.<ref>''A tourist map of the Nullarbor Plain Perth to Adelaide'' Scale 1:2,250,000 (E 116°00' --E 139°00'/S 30°00'--S 38°00') Unley, S.
