Great Barrier Reef History

The Great Barrier Reef has been home to Australian Aboriginal and Torres Strait Islanders for thousands of years.  It is an integral part of their Culture, belief systems and spirituality.

As expected, the Reef is a must-see location for tourists, especially in the Cairns region.

Australia’s Great Barrier Reef generates more than one billion dollars each year.  Tourism is the main economic activity in this area.

Dolphins and Whales

This region supports a great diversity of life, including many endangered species, 30 whales, dolphins, and porpoises recorded in the Great Barrier Reef.

These include large dugongs, the dwarf minke whale, the Indo-Pacific humpback dolphin, and the humpback whales.   More than 1,500 species of that life are on the Great Barrier Reef, including the clownfish, red bass, red-throat emperor, and coral trout and snapper.

Seventeen sea snakes live in warm waters up to 50 metres deep on the Great Barrier Reef.  Sea snakes are much more common in the southern area of the Reef than in its northern section.


At certain parts of the year, six different sea turtles come to the Reef to breed.  This group includes the green sea Turtle, leatherback sea Turtle, hawksbill Turtle, loggerhead sea Turtle, flat-back Turtle and olive ridley Turtle.

Green sea turtles on the Great Barrier Reef have two genetically distinct populations, one located in the northern part of the Reef and the other in the southern.  Sea turtles frequently visit the Cairns’ outer barrier Reef locations and Green Island.

Fortunately, there are also 15 species of sea-grass beds attracting both dugongs and turtles and providing fish habitat.

Sharks and Rays

The Great Barrier Reef is also home to some of the predators of the ocean world.

One hundred twenty-five sharks, stingrays and chimaera live on the Reef.   At night scuba divers are eager to see sharks during the night dive.


Five thousand mollusc species live on the Reef,  including the giant clam.   Snorkellers and divers can see nudibranchs of all different colours along the Reef.


Two hundred fifteen birds visit the Great Barrier Reef and regularly nest on some islands.

Namely, the white-bellied sea eagle, one of the 1.7 million birds, comes to the area to use the sites for breeding.


The Great Barrier Reef islands support 2,195 types of known species of plants.

The southern islands, particularly the Whitsunday Islands region, are the most diverse, supporting 1,141 species propagated by birds.
