The Best Dive Sites on the Great Barrier Reef
Coral health, fish life, and reputation among divers who have dived the whole reef.
The Great Barrier Reef has more than 2,900 individual reefs and hundreds of named dive sites, from the day-boat moorings off Cairns to the Ribbon Reefs and the southern coral cays. These are the ones divers travel for, grouped from north to south. The Coral Sea reefs beyond the shelf (Osprey, Bougainville, Flinders) are covered in the big-animal and Coral Sea lists.
