Fraser Island is situated off the southeast coast of Queensland and is separated from the mainland by the Great Sandy Straits and Hervey Bay. Fraser Island is the world's largest sand island, almost 110 km long and ranges in width from about 7 to 23 km . The island's sandhills, which are up to 400,000 years old, rise to heights of about 240 m. Rain forests grow on the sand dunes of Fraser Island, unlike on other sand islands.Large stands of Hoop, kauri, blackbutt, and satinay trees are common. There are more than 40 deep freshwater lakes on the island, some of which are perched high above sea level. Lake Boemingen, the largest of these lakes, is almost 500 acres in area.

The island is exceptionally rich in plant life, with well-preserved tidal marshes, subtropical rain forests and large expanses of mangroves on the western side of the island, and areas of open forests on the east.

Access to Fraser Island is via vehicular barges operating from Inskip Point at Rainbow Beach, or by charter aircraft or boat.

Four-wheel drives are the only practical means of vehicle transport on the island, so if you don't have one of your own, hire one, or take a Fraser Island Safari Tour.
