Australia covers 7,692,024 square kilometers, making it the sixth-largest country by land area. The distance between Perth and Sydney measures 3,935 kilometers by road, roughly equivalent to driving from Paris to Baghdad. The distance from Melbourne to Cairns spans 2,732 kilometers.

The nation operates as a federation of six states and two territories. New South Wales, Victoria, Queensland, South Australia, Western Australia, and Tasmania function as states. The Australian Capital Territory and Northern Territory function as territories under direct federal oversight. Each state maintains separate transport regulations, road rules variations, and infrastructure funding priorities. Victoria requires bicycle helmets by law since 1990. Queensland permits left turns on red lights at specific intersections. South Australia allows 130 kilometers per hour speed limits on certain rural highways. These variations require attention when crossing state borders.
