Fraser Island, situated off the east coast of Queensland, Australia, is a remarkable natural wonder that captivates the imagination of adventurers and writers alike. Shaped like a well-worn thigh boot, this 77-mile long island is entirely made of sand, with beaches and dunes of golden sand stretching along its shores. However, behind this sandy facade lies an astonishingly varied canopy of vegetation, with sand heaped up to 785 feet high supporting dense and sometimes luxuriant forests.

Formation of the Island
Fraser Island began to take shape millions of years ago when mountains on the mainland to the south were eroded by wind and rain. Fine debris was swept into the ocean, carried northwards by currents, and gradually accumulated on the ocean floor. Then, during the Ice Age, falls in sea level caused the accumulating sand to become dry land and blown into massive dunes. During rises in sea level, ocean currents brought in more sand.
Flora and Fauna
The island’s high rainfall of over 60 meters (1500mm) a year encourages a cycle of growth and decay on the sands. Arrow-straight satinay trees, found in few places in the world, grow here – their trunks were used to line the Suez Canal in the 1920s. Scribbly gum trees – named after the marks left on their bark by burrowing insects – dominate the island’s shrubby heathlands.
History and Cultural Significance
Fraser Island takes its name from Eliza Fraser, the woman who brought it to the world’s attention. In 1836, a group of shipwrecked Europeans struggled ashore from one of their ship’s small boats. Among the party were the ship’s captain and his wife Eliza Fraser, but by the time that rescue arrived two months later, several of the party, including the captain, were dead. Mrs Fraser alleged that her husband had been murdered by the island’s Aborigines, the Butchulla people. In London, she told increasingly lurid tales of her time on the island, describing them to the public, for a fee of sixpence, in a tent in Hyde Park.
Conservation Efforts
Fraser Island is now a protected World Heritage site, recognized for its natural and cultural significance. The island is home to more than 40 lakes, and although it is made up of sand, it is far from being a giant, free-draining sandcastle. Under the island, the sand has cemented together with hummus and minerals to form a water-tight pan that traps the island’s plentiful rainfall. Here and there, the ground surface drops below this water table to form crystal-clear lakes, such as Lake Wabby.
Our Take on Fraser Island
Fraser Island is a true testament to the power of nature and the resilience of life. Despite its harsh environment, it supports a diverse range of flora and fauna and has a rich cultural history. As a protected World Heritage site, it serves as a reminder of the importance of conservation and the need to protect our natural wonders for future generations.
