Sandblows & Coloured Sand Dunes of Fraser
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. Fraser is the world's largest sand island. Along the ocean coastline, the dunes take on at times sculptured shapes, giving rise to the names 'The Cathedrals' and 'The Pinnacles'.
There are 72 different coloured sands that occur on the island. The best coloured sands can be seen along a 35km stretch of the ocean beach north of Happy Valley.
Sandblows are the other major sand formation, caused through the gradual action of shifting sand across the island. The Knifeblade, just north of the wreck of the "Maheno", is the largest of the island's sandblows. A lookout provides excellent views.
