K’gari helped form the Great Barrier Reef.

When K’gari was formed around 1 million years ago, sands from Australia’s southeast shores were carried north by wind and ocean currents. They settled on a volcanic landmass and formed the sand dunes of K’gari! This newly formed sand island created a barrier in the ocean. Most of the sand congregated around K’gari, leaving the seas in southeast Queensland much clearer than before. This allowed corals to flourish underwater, and thus the lower parts of the Great Barrier Reef were formed!
