The island has rain forests, 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.
Fraser Island, off the east cost of, is a stunning sight. Waves of crystal clear water crash onto sandy beaches. The aborigines who first lived there called it k’gari. It means paradise, and that exactly what it is. Fraser island is a world heritage site because of its unique natural surroundings. It is the largest sand island in the world. It has more sand than the sahara desert. Huge sand dunes move slowly across the island with the wind. In the valleys between dunes are freshwater lakes. There are over 100 of these small, clean lakes all over the island.
