Fraser Island lies just off the east coast of Australia. At 122km long and 22km wide, covering an area of 184,000 hectares, it is the largest sand island in the world.

Majestic remnants of ancient rainforests grow in sand along the banks of fast-flowing, crystal-clear creeks running from over 100 freshwater lakes, some tea-coloured and others crystal clear and blue, all ringed by white sandy beaches. These freshwater lake make up half of the world's perched freshwater dune lakes and are found just inland from the beach.

Fraser Island's long uninterrupted white beaches are flanked by immense sand blows and cliffs of coloured sands are part of the longest and most complete age sequence of coastal dune systems in the world and they are still evolving.

They are a continuous record of climatic and sea level changes over the last 700 000 years. The highest dunes on the island reach up to 240 metres above sea level.

The combination of shifting sand-dunes, tropical rainforests and lakes makes Fraser Island an exceptional site but, even with its protected status, there is a huge amount of marine debris that accumulates here.
