The Great Barrier Reef, Queensland
As the largest living structure on the planet, the Great Barrier Reef is incredibly rich and diverse.
Stretching 2300 kilometres, this natural icon is so large it can even be seen from outer space.
While it’s known mostly for its large maze of colourful reefs, its intricate architecture also provides a home for a huge number of plants and animals.
Some of these, such as turtles and crocodiles, have been around since prehistoric times and have changed little over the millennia.
The breathtaking array of marine creatures includes 600 types of soft and hard corals, more than 100 species of jellyfish, 3000 varieties of molluscs, 500 species of worms, 1625 types of fish, 133 varieties of sharks and rays, and more than 30 species of whales and dolphins.
The Great Barrier Reef is also unique as it extends over 14 degrees of latitude, from shallow estuarine areas to deep oceanic waters.
Within this vast expanse are a unique range of ecological communities, habitats and species – all of which make the Reef one of the most complex natural ecosystems in the world.
The Great Barrier Reef Marine Park:
The rest of the Marine Park 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 250km offshore.
Rather than having one level of protection throughout the Marine Park, the area is instead divided into different zones. Each zone has different rules outlining permitted activities and those that are prohibited.
Just how big is the Great Barrier Reef Marine Park?Covering 344,400km2, the Great Barrier Reef Marine Park is:
The Belize Reef off the Caribbean coast of Belize is the second longest barrier reef in the world at 290 km, while Ningaloo Reef off the West Australian coast is 280 km long.

The Great Barrier Reef Marine Park:
- covers 344,400 km2 in area
- includes the world’s largest coral reef ecosystem
- includes some 3000 coral reefs, 600 continental islands, 300 coral cays and about 150 inshore mangrove islands
- extends south from the northern tip of Queensland in north-eastern Australia to just north of Bundaberg
- is between 60 and 250 kilometres in width
- has an average depth of 35 metres in its inshore waters, while on outer reefs, continental slopes extend down to depths of more than 2000 metres
- was created in 1975 through the Great Barrier Reef Marine Park Act
- extends into the airspace above and into the earth beneath the seabed.

Just how big is the Great Barrier Reef Marine Park?Covering 344,400km2, the Great Barrier Reef Marine Park is:
- bigger than Victoria and Tasmania combined
- bigger than the United Kingdom, Switzerland and Holland combined
- roughly the same area as Japan, Germany, Malaysia or Italy
- approximately half the size of Texas
- slightly smaller than the entire Baltic Sea.
