 The Western Australian section of Eyre Highway is on the western side of the Nullarbor Plain ; the South Australian section crosses the eastern section of the Nullarbor Plain , and the top of the Eyre Peninsula . The Nullarbor gets its name from Latin for " no tree " , and the typical view is that of a straight highway and practically unchanging flat saltbush @-@ covered terrain , although some parts are located on ridges . The Eyre Peninsula has been extensively cleared for agriculture , although there are remnant corridors of native eucalyptus woodland alongside its roads .
