The Great Barrier Reef is a site of remarkable
variety and beauty on the north-east coast of Australia. It contains the
world’s largest collection of coral reefs, with 400 types of coral,
1,500 species of fish and 4,000 types of mollusc. It also holds great
scientific interest as the habitat of species such as the dugong (‘sea
cow’) and the large green turtle, which are threatened with extinction.
