Meet the site
Beaver Reef is the main outer-reef destination from Mission Beach and the primary site for Mission Beach Dive. It lies about 40 km offshore, roughly 90 minutes by boat from Clump Point, in a Marine National Park (Green) Zone where fishing and collecting are prohibited, and its fish populations and coral condition reflect that protection. Mission Beach Dive describes a gently sloping coral wall descending from 5 m to 18 m, with staghorn, table and brain corals in the shallows and sea fans and sponge gardens deeper, and visibility of 15-30 m in the best conditions, optimal from May to November. Great Barrier Reef Tours divides the reef into two main areas: Beaver Cay on the northern side, with lush coral gardens, and Shark Alley on the southern side, known for sloping coral walls, pelagic fish and whitetip and blacktip reef sharks, with coral gardens at 12-22 m. Green turtles are frequent residents, and giant moray eels, clownfish and giant clams are common. Visitors on snorkel trips report blue and orange sea stars, anemonefish, angelfish and chromis over bommies that rise to within metres of the surface. The site suits all levels: beginners and Discover Scuba divers can stay in the shallow gardens, while experienced divers head to Shark Alley. Because Mission Beach is closer to the outer reef than Cairns, Beaver gives outer-reef diving with less travel and far fewer boats; it is common to have the reef to yourself. Trips run in small groups and not every day.
