About this site
Milln Reef is an outer reef on the Great Barrier Reef, reached by boat from Cairns. It offers wall dives, pinnacles and swim-throughs.
Dives here run from 5 to 25 metres. Currents are mild and visibility is 15 to 20 metres. It is also good for night diving.
Some of the walls hold sleeping parrotfish in their mucus cocoons. Turtles and barracuda are seen here, along with the occasional ray.
