Coral Sea dive sites

Osprey Reef is accessible only by liveaboard dive vessel from Cairns or Port Douglas. The journey takes approximately 12-14 hours, with most boats departing in the evening and arriving at the reef by dawn. Liveaboard trips typically range from 3 to 7 nights, with Osprey Reef combined with other Coral Sea reefs like Bougainville and Holmes Reefs, or with the northern Great Barrier Reef's Ribbon Reefs and Cod Hole. Major operators include Spirit of Freedom, Mike Ball Dive Expeditions, and Spoilsport.

The North Horn shark feed is one of the most exhilarating experiences in Australian diving. Divers descend to a ledge at around 20-25 metres on the reef promontory. A bin of fish scraps is lowered, and within minutes, grey reef sharks in groups of 20 to 40 converge on the area. Silvertip sharks, larger and bolder, push through the grey reef sharks for access. The action is intense but controlled, with experienced dive guides managing the feed. On exceptional days, hammerheads and even tiger sharks make appearances from the deep blue.

Advanced Open Water certification is required for most dives at Osprey Reef, with many operators requesting a minimum of 50 logged dives. The site features strong currents, deep walls, and open blue water conditions that demand solid diving skills. The shark feed dive typically takes place at 20-25 metres, and wall dives can descend to 40 metres. Current experience and comfortable buoyancy control are essential. Most liveaboard operators also offer a pre-trip checkout dive on the Great Barrier Reef.
