The Great Barrier Reef (GBR) was World Heritage-listed in 1981 and is considered one of the World’s Seven Natural Wonders. It covers 344,400 square kms, is 2,300 km long or approximately half the length of the Eastern Australian coastline. It comprises 3,000 individual reefs, 300 coral cays, 600 continental islands and 150 inshore mangrove islands, making it the largest barrier reef in the world.

Apart from its size, the GBR has high levels of biodiversity and is considered one of the most complex natural systems on earth. With over 600 types of soft and hard corals, more than 100 species of jellyfish, 3,000 varieties of molluscs, 500 species of worms, 1,625 types of fish, 133 different species of sharks and rays, six out of the seven sea turtles found in the world and more than 30 species of marine mammals, it is an enormous ecosystem.
