 Aboriginal¹ people would have lived here too. Hunting the wildlife in areas that are now deep underwater. Then the end of last ice age, ice of the poles melted and sea levels rose all around the round flooding this lowline coast. This happened nearly 10,000 years ago. In fact, stories of the great flood still pass down in aboriginal culture. As the sea rose, corals began to grow on the Rockey frenches of the continental² shelf creating the Great Barrier Reef we see today. The shallow tropical waters are clear and warm. Perfect conditions for corals to thrive. 

Sheltered behind this long straight of reef, Alagoon was born. An area protected water larger in size than the whole of Great Britain. And a new coastal³ line too which shallows Sandy waters. The rising sea also cut a various of high ground creating the 600 islands that adopt the Agoon.
