Island Ecology

Situated in the World Heritage listed Great Barrier Reef Marine Park, Green Island is a very unique island. It is one of 300 sand cays on the Great Barrier Reef, but it is the only one with a rainforest.

A true coral cay, Green Island is around 6000 years old and was formed by a build up of sand sediments, animal and coral deposits to above sea level. It is 15 hectares (approx 37 acres) in size and takes around 45 minutes to walk around.
