Create an itinerary including Boomanjin lake
Lake Boomanjin is a large perched lake in the Fraser Coast Region of Queensland, Australia. The lake is located on Fraser Island (also known as K'gari and Gari) in the Great Sandy National Park.
Lake Boomanjin is considered the largest perched lake in the world, meaning that the lake floor is above the water table. It is one of 40 perched lakes on Fraser Island, all of which make up half of the known perched lakes in the world.
The lake is known for its reddish brown color, which is caused by colored dissolved organic matter including tannins from tea trees growing in its watershed. Its inflow comes from two small creeks that pass through wallum swamp, providing the sources of the dissolved matter that creates the unique color. Lake Boomanjin’s floor is covered in white quartz-rich sands. Carnivorous plants, bladderworts, can be found near the lake.
Compared to nearby lakes with clearer water, Lake Boomanjin gets less attention from tourism overall. There is a campsite on Lake Boomanjin managed as part of the K’gari Recreation Area within Great Sandy National Park.
Lake Boomanjin is a sacred location for the Butchulla People, the original inhabitants of the Fraser Coast Region.

  • We visited Boomanjin Lake yesterday and it was stunning! While Lake McKenzie has the blue waters, this one has coloured sands and beautiful surrounds. We didn’t swim, but sat beneath some gum trees...

  • Not as pretty as Lake McKenzie but probably quieter. The water is coloured by the tannins from the surrounding tea trees so it has that orange tinge. Some interesting flora though.
  • Lake Boomanjin is one of the bigger inland lakes of Fraser Island. It is not too far from Eurong but is not as busy so you can often have the whole lake to yourself. The water is pure and fresh and safe for swimming.
