Every year, more than two million people come from all part of the world to visit Australia’s great, natural wonder.

The Great Barrier Reef is the world’s biggest, single structure made by living organisms. It’s so big, it can be seen from outer space.

The Reef has existed for more than 500,000 years and its evolution is truly amazing.

Coral reefs are formed when coral larvae attach to rocks, or other hard surfaces in the water, usually alongside islands or continents.

The Great Barrier Reef was formed from living coral growing on dead coral, that might be twenty million years old.

The Reef itself stretches for over 3,000km up the Queensland coast. It is home to more than 400 different kinds of coral, 1500 species of tropical fish and around 30 types of reptiles.

To experience this great wonder for yourself, the Great Barrier Reef can be accessed by air or water. A range of tour operators depart from the island daily.
