Sandy Island (Windy Harbour)

Sandy Island is a 20 ha (49 acres) island lying about 5 km (3.1 mi) off the coast of Windy Harbour in south-west Western Australia, and near Point D'Entrecasteaux.

It is part of D'Entrecasteaux National Park and is an important breeding site for seabirds.

Most of the island is vegetated with Poa tussock grassland, pigface and Lobelia anceps.

[1] The island has been identified by BirdLife International as an Important Bird Area because it supports a high proportion of the nesting population of flesh-footed shearwaters (with up to 300,000 breeding pairs) and has supported relatively high numbers of breeding fairy terns.

[2] Other birds recorded breeding on the island are little shearwaters, sooty oystercatchers and silver gulls.
