Lake Boomanjin is a large perched lake in the Fraser Coast Region of Queensland, Australia. The lake is located on K’gari (Fraser Island) 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 K'gari, 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.

  • Really nice lake with a really steady incline of depth. Great for swimming with younger people. Not usually many people here either which is great
  • Gorgeous spot for a picnic or to camp (if you're walking in). Would recommend anytime of the year!
