The Island is 125km long and over 160,000 hectares in area. It was formed during the ice age when the prevailing winds transported the vast quantities of sand from New South Wales and deposited it along the coast of Queensland forming the island as we know it today. In this fragile eco system the rainforest consists of huge satinay and brush box, kauri pines, piccabeen palms and the rare angiopteris fern which is one of the largest ferns in the world. All this growing in pure sand!
 Fraser Island - a unique ecosystem The dune systems of the Great Sandy Region, which include Fraser Island, are the largest and oldest in the world dating back more than 30,000 years. There are 72 different coloured sands that occur on Fraser Island. Sandblows are the other major sand formation, caused through the gradual action of shifting sands across the island.
Stunning Lake McKenzie is one of the island's Perched lakes - a unique geographical anomaly where a lake is formed above the water table. Saucer-shaped depressions with a hard, impervious base of organic matter and sand form a catchment for the rain eventually creating a lake.
