My experience
Done in February 2010. I dived the reef on an extension to a work trip to Australia.
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 (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi).
The Spectacular reef is located in the Coral Sea, off the coast of Queensland, Australia and can be seen from outer space and is the world’s biggest single structure made by living organisms.
