The Great Barrier Reef is the world’s largest coral reef system composed of over 2,900 individual reefs, and 900 islands stretching for over 2,300 kilometres over an area of approximately 344,400 square kilometres. The reef is located in the Coral Sea, off the coast of Queensland, Australia.

This reef structure is composed of and built by billions of tiny organisms, known as coral polyps.

A large part of it is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, such as fishing and tourism.
