Cape Leeuwin is the most south-westerly mainland point of the Australian continent, in the state of Western Australia.
A few small islands and rocks, the St Alouarn Islands, extend further in Flinders Bay to the east of the cape. The nearest settlement, north of the cape, is Augusta. South-east of Cape Leeuwin, the coast of Western Australia goes much further south. Located on headland of the cape is the Cape Leeuwin Lighthouse and the buildings that were used by the lighthouse keepers.
In Australia, the Cape is considered the point where the Indian Ocean meets the Southern Ocean; however most other nations and bodies consider the Southern Ocean to only exist south of.
