Dive sites in the Great Barrier Reef should be included in every diver’s “must-see” list. One of the most remarkable dive sites on the Northern end of the Great Barrier Reef is Cod Hole. The ribbon of reefs extends for about 97km/60mi north of Cairns. Diving at Cod Hole is fascinating because divers can enjoy coral reefs, caverns, and dozens of marine species. The average depth is 15m/49ft. Divers can see gorgonians and cod at the maximum depth of 32m/105ft. There are weak currents (1 knot), due to the fact that this site is open to the ocean. Cod Hole is suitable for divers of all experience levels, and can only be reached by liveaboard (divers will spend at least one night on board)
When To Go Diving
The climate in Port Douglas and Cairns is tropical, and divers can dive at Cod Hole all year. Summer lasts from December to February, and rains are common during this season. The average temperature is about 30°C/86F°. In the summer, the water temperature is approximately 22°C/71°F, and in the winter it is up to 29°C/84°F. Divers who want to see minke whales should dive at Cod Hole from June to August because the site is along their migratory path during this time
What to see
Huge cod are found here all year round. Divers can also spot Maori wrasses, sharks, pelagic fish, frogfish, boxfish, parrotfish, barracudas, angelfish, and coral trout. There are a lot of soft and hard corals, coral pinnacles, and drop-offs for stunning scuba diving in Cod Hole. Divers usually take their cameras to take photos of feeding the cod, which has been used to divers over the past 30 years. Cod Hole is a must-see dive site during the liveaboard diving on Great Barrier Reef
