The Great Barrier Reef, off the east coast of Australia
The Great Barrier Reef is the only living organic collective visible from Earth’s orbit.
The Great Barrier Reef, off the east coast of Australia, is one of the wonders of the natural world – it is the world’s largest coral reef ecosystem. It was declared a World Heritage area in 1981 and added to the National Heritage List in 2007.
The Great Barrier Reef is scattered with beautiful islands and idyllic coral cays and covers more than 300,000 square kilometres and ranges from Torres Strait in the north to the unnamed passage between Lady Elliot Island (its southernmost island) and Fraser Island in the south. The Great Barrier Reef system consists of more than 3000 reefs which range in size from 1 hectare to over 10,000 hectares in area.
