Fraser Island Quiz – Paradise Made of Sand

K'gari, formerly Fraser Island, lies off the coast of Queensland and is the largest sand island in the world. The Butchulla people are its traditional owners, and the name K'gari, meaning paradise, became official in 2023.

The island holds about half of the world's known perched lakes, which sit above the water table on layers of hardened organic matter. Lake McKenzie is famous for clear blue water over white silica sand, while Lake Wabby is slowly being swallowed by a sand blow.

Rainforest grows directly from sand, 75 Mile Beach serves as a highway and runway and the wreck of the SS Maheno has rested there since 1935. Dingoes, called wongari, roam freely, and UNESCO listed the island in 1992.
