About this site

Thetford Reef is a coral reef dive site off Cairns on the Great Barrier Reef, rated beginner with great visibility. The season runs from April to September, and access depends on tidal and weather conditions.

The reef has a number of species of hard and soft coral, and there is a magical light as divers swim through some of the enclosed swim-throughs. Blue staghorn thickets and small coral patches grow on the sandy floors, and boulder coral heads carry multi-coloured Christmas Tree Worms.

Butterflyfish, angelfish, rabbitfish, damselfish, pipefish, giant clams, anemones and transparent shrimp can be seen here. Care is needed when passing large Gorgonian fans and soft coral.
