This vast expanse of flat, almost treeless country is a testament to the geological forces that have shaped the continent over millions of years. The name "Nullarbor" is derived from the Latin words "nullus" meaning "no" and "arbor" meaning "tree", a fitting description of this treeless landscape. The Nullarbor Plain is a region of extreme climate, with scorching summers and cold winters, where the sun beats down relentlessly and the rain is scarce.
