The coastline of Australia comprises the coasts of mainland Australia and Tasmania. It nominally includes a part of all Australian states and territories; the otherwise landlocked Australian Capital Territory has a coastal enclave at Jervis Bay Territory.

According to The World Factbook, Australia has the sixth longest coastline in the world, at 25,780 kilometres (16,020 mi).[1][2]

Due to the historical context of European discovery and exploration, the coastline has been the first point of contact over 400 years.[3]

In the IBRA bioregionalisation, the coast has 36 coastal bioregions that define the whole coast[4] and there is the more complex Integrated Marine and Coastal Regionalisation of Australia, which includes ecological features that are beyond the shoreline.
