Fraser Island, Australia

Fraser Island is the largest sand island in the world with an area of ​​1840 km2, a length of 123 km, a width of about 25 km and a peak up to 260 meters. Sand accumulated along this portion of the Queensland coast for some 750,000 years, in part because the volcanic basement is a kind of natural barrier for sediment carried down the eastern seaboard by a strong current. The island was declared a World Heritage Site by UNESCO in 1992.
