Infographic: Great Barrier Reef Fast Facts

GBR Infographic Fast Facts:  The World's Largest & Most Extensive Coral Reef System      

  • The Great Barrier Reef is the largest and most extensive coral reef system in the world comprising about 2900 individual coral reefs, 600 continental islands and 300 coral cays.
  • It represents approximately 10% of all coral reefs in the world.
  • The Great Barrier Reef spans two thirds of the north eastern coastline of Australia extending north from Bundaberg on Queensland’s coast to Cape York, the northern tip of Australia.
  • It is 2300 kms long and approximately 350 000 kms2 in size.  That’s about 70 million football fields or the size of Japan
  • It is the largest natural feature on earth and its impressive size makes it the only living structure that can be seen from the moon.

Fast Facts: World Class, World Heritage

  • The Great Barrier Reef is recognised internationally as one of the world’s greatest natural wonders
  • Its outstanding natural significance was recognised in 1981 when it became the first coral reef system in the world to be awarded World Heritage status. It is the world’s third largest World Heritage Area. 
  • The Great Barrier Reef meets all four of the natural criteria for World Heritage listing, one of only a handful of natural areas on earth to do so. 
  • Over 99% of the Great Barrier Reef World Heritage Area is protected within the Great Barrier Reef Marine Park and about 50% of its islands are protected by National Park status. This ensures the coral reef system and its inhabitants are protected effectively and preserved for future generations to enjoy.
    • The Great Barrier Reef is renowned as one of the world’s healthiest reef systems.  This is due in part to innovative management and its status as a protected area.
