#UNESCO World Heritage site
One of the 7 natural wonders of the world.
Largest living structure on the planet, so big it’s visible from space.
The size of about 70 million football fields or the size of Japan or Italy. It eclipses the world number two, the Caribbean’s Belize Reef, which is a mere 290 km long.
World Heritage Listed in October 1981.
Spans 348,000 km2, which is slightly more than the 344,400 km2 Great Barrier Reef Marine Park area because it also includes some 980 islands, internal waters, intertidal areas and other state waters.
7% of the World Heritage area is made up of coral reefs. The rest is an extraordinary variety of marine habitats, ranging from shallow inshore areas – such as seagrass, mangroves, sand, algal and sponge gardens, and inter-reefal communities – to deep oceanic areas more than 250 km offshore.
Inshore waters average a depth of around 35 metres while on outer reefs the plunge is more than 2,000 metres.
November, spawning season, is when the corals get busy reproducing. Resembling an underwater snowstorm, the exact timing of the annual spawning release is linked to water temperature and phases of the moon.
