Fraser Island is an island located along the southern coast of Queensland, Australia, approximately 200 kilometres (120 mi) north of Brisbane. Its length is about 120 kilometres (75 mi) and its width is approximately 24 kilometres (15 mi).
The island is considered to be the largest sand island in the world . It is also Queensland's largest island, Australia's sixth largest island and the largest island on the East Coast of Australia.
The island has rainforests, eucalyptus woodland, mangrove forests, wallum and peat swamps, sand dunes and coastal heaths. It is made up of sand that has been accumulating for approximately 750,000 years on volcanic bedrock that provides a natural catchment for the sediment which is carried on a strong offshore current northwards along the coast.
