Hayman Great Barrier Reef. Australasiaâs most exclusive private island resort â the five-star Hayman Great Barrier Reef, situated just offshore from Queensland, Australia â is poised to reopen next month following temporary closure for property restoration.
The Great Barrier Reef is a mosaic of 2,900 individual reefs off the coast of Queensland in northeast Australia. The sprawling reef can be seen from space and is not only the world's largest coral reef system but also the largest structure on Earth made by living organisms. Where is the Great Barrier Reef? The Great Barrier Reef stretches more than 1,600 miles (2,575 kilometers) â a little more than the distance from Boston to Miami. It covers an area of 133,000 square miles (344,400 square km), reaching from the Torres Strait at it northernmost point to Fraser Island in the south. The reef includes Lady Elliot Island and the smaller Murray islands. Great Barrier Reef animals
