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. Home to over 1,500 species of fish, abundant marine life and over 200 types of birds, it’s also one of Australia’s greatest conservation successes. A World Heritage Area since 1981 (the world’s first reef ecosystem to be recognised by UNESCO), it is highly protected and one of the best-managed marine areas on Earth.
The reef is located in the Coral Sea, off the coast of Queensland, Australia.
