What Is A Sand Blow?

K'gari (Fraser Island) is famous for being the largest sand island in the world. Estimated to be around 700,000 - 1 million years old, the island formed when nature's ocean and wind currents caused sands to shift along the east coast of Australia and settle in the area that is now K'gari

A similar process formed the Hammerstone Sand Blow! Sand blows form when natural causes create a huge mass of sand, similar to a sand dune. The sand dunes on K'gari are part of the largest and most complete collection of coastal sand dunes in the world! Carlo Sand Blow is another famous spot on the mainland near Cooloola Bay. A sand blow will settle in one place when it is protected from offshore winds, but they are constantly moving and changing over time.

Hammerstone Sand Blow and Lake Wabby

Due to the constant shifting of sands on K'gari, the Hammerstone Sand Blow helped create Lake Wabby thousands of years ago. Sand blows can often swallow forests and vegetation, creating a desert-like landscape. A moving sand blow can also create new lakes when the sand blocks a river from reaching the ocean. That is how the Hammerstone Sand Blow created Lake Wabby! 

Lake Wabby is known as a barrage or barrier lake, which forms when a body of water is stopped from reaching the ocean and becomes a stagnant lake. As the deepest lake on K'gari, Lake Wabby has refreshing, clean water that is a rich green color due to the nutrients and algae that thrive in the lake. It is one of the best places to swim on K'gari, and the sand dunes and rainforests create other-worldly scenery here!

Absolutely, the Hammerstone Sandblow is a magical place. It's rare to find a landscape that looks like a desert, yet is surrounded by lush rainforests and freshwater lakes.

These are some of the most ancient sand dunes in the world, and strolling across the ripples of golden sand is a mesmerizing experience!

Another reason why you should head to the Hammerstone Sand Blow and Lake Wabby is the fact that it may not exist forever! As we've discussed, sand blows on K'gari are constantly moving and changing.
