  • 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.
  • Practically the entire ecosystem was inscribed as World Heritage in 1981, covering an area of 348,000 square kilometres and extending across a contiguous latitudinal range of 14° (10°S to 24°S).
  • The GBR, extending 2,000 kilometres along Queensland's coast.
  • The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms.
