Perth, Australia

Perth is the capital and largest city of Western Australia. It is separated from Adelaide (the nearest city with over one million inhabitants) by a distance of 2,139 km, including the vast spaces of the Nullarbor Plain.

Perth spreads out along on a flat coastal plain, dissected by the Swan River, and spreads over the Darling Scarp to the east. The Indian Ocean coastline to the west is its only distinct physical boundary making it the most isolated continental city anywhere in the world.
