Diving - Coral Reef

The Great Barrier Reef is an extremely ancient, enormous host of living things, composed of living coral growing on dead coral dating back perhaps as much as twenty million years.

Many generations of dead coral have built themselves into great walls of stone covered in a diverse range of living organisms such as coral, algae, anemones, sponges, fish, worms, starfish, turtles, molluscs, snakes, crustaceans, and an extraordinary array of thousands of species of plants and animals.

Although there is no direct physical evidence, first human contact with the reef must’ve occurred for some time. We know that Aboriginal people occupied great parts of the Australian continent for around 40,000 years. Aboriginal and Torres Strait Islander peoples have fished and hunted its waters and navigated between the islands of the reef region.

For large parts of that time, during periods of glacial activity, the area of the Great Barrier Reef was dry with large flat coastal plains. This area is at a depth of less than one hundred metres below sea level today.
