Location of 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.
The island is aligned north-west to south-east, about 800 m (2,600 ft) long by 300 m (980 ft) wide, flat and mainly sandy. There is an area of limestone and unconsolidated dune at the north-western end. The southern coastline is composed of migmatitic rocks. Most of the island is vegetated with Poa tussock grassland, pigface and Lobelia anceps. Some 46 plant species have been recorded.[1]
