Quick Navigation

The Great Barrier Reef Marine Park is located in Queensland in the waterways off the northeastern coast of Australia. The park boundaries encompass an area of 132,806 square miles (343,966 sq km) which accounts for much of the barrier reef.

The Great Barrier Reef extends across a distance of 1,400 miles (2,300 km) with over 2,900 individual reefs creating the largest coral reef system in the world. This accounts for approximately 10% of the world’s coral reefs.

This complex system of reefs is the largest single structure created by living creatures and it may be seen from outer space. It is a UNESCO World Heritage Site and one of the Seven Natural Wonders of the World.

Collectively, the Great Barrier Reef is comprised of deltaic reefs, ribbon reefs, lagoonal reefs, fringing reefs, and planar reefs.

The 2,900 reefs are home to an abundance and variety of marine species such as coral, bony fish, rays, sea snakes, sea turtles, sharks, and various aquatic mammals. Many of the species found in the reef are vulnerable or endangered.

There are over 1,500 species of fish, six species of turtles, 5,000 species of mollusk, nine species of seahorses, and approximately 215 species of birds. Saltwater crocodiles can be seen in the mangroves and salt marshes along the fringe of the national park. The deeper waters have minke whale, humpback whale, dolphin, and dugongs.


As one of the Seven Natural Wonders of the World and one of the greatest marine biodiversity ecosystems in the world, exploring it is a highlight. Visitors should look to experience many of the different islands and reef areas while exploring from underwater and above in the skies.
