Opal Reef

Opal Reef, in the heart of the Coral Sea, is one of the Great Barrier Reef’s more sheltered sites, set in a curve that creates an area of clear water that’s perfect for a snorkelling experience. Snorkellers and divers alike are wowed by rich and diverse corals, vibrant clam species, stingrays on the sandy floors and schools of snapper and bass.

Opal Reef is also famous for the abundant marine life on the reef’s patches of sand, such as sea cucumber and perch, while further below lie eye-catching sweetlip and titan triggerfish.

This is one of the less visited reefs and is best known for the beautiful Flower Gardens. Here, corals are abundant and there’s a chance to pass the many dancing feather stars that call it home. You may also encounter parrotfish, wrasse, nudibranchs (strikingly coloured soft molluscs), butterfly fish and crabs.
