Augusta is a town on the south-west coast of Western Australia, where the Blackwood River emerges into Flinders Bay. It is the nearest town to Cape Leeuwin, on the furthest southwest corner of the Australian continent. In the 2001 census it had a population of 1,091; by 2011 the population of the town was 1,292 (excluding East Augusta).
The town is within the Shire of Augusta-Margaret River local government area, and is in the Leeuwin Ward. It is connected by public transport to Perth via Transwa coach service SW1.
Augusta was a summer holiday town for many during most of the twentieth century, but late in the 1990s many people chose to retire to the region for its cooler weather. As a consequence of this and rising land values in the Augusta-Margaret River area, the region has experienced significant social change.
