Cod Hole

Cod Hole: A Great Barrier Reef Diving Paradise

The Cod Hole is a world-renowned dive site on the Great Barrier Reef, famed for its resident population of massive Potato Cod and stunning coral formations. This site offers unforgettable encounters with some of the reef's most impressive marine life in a relatively shallow and protected environment.

Marine Life

• Giant Clams
• Coral Trout
• Wrasse
• Reef Sharks (White-tip and Black-tip)
• A variety of colourful reef fish

Best Time to Visit

The best time to dive the Cod Hole is generally during the dry season, from May to October. This period offers the best visibility, calmer seas, and lower humidity. While diving is possible year-round, the wet season (November to April) can bring occasional rain, reduced visibility, and potential for strong winds.

What Makes It Special

What sets the Cod Hole apart is the sheer size and accessibility of the Potato Cod population. The controlled feeding practices over many years have resulted in these fish becoming remarkably accustomed to divers. The relatively shallow depth also allows for longer bottom times and makes it accessible to a wider range of diving abilities. Furthermore, the vibrant coral gardens surrounding the 'Hole' provide a stunning backdrop.

Practical Tips

When diving the Cod Hole, consider these points:

• Choose a reputable dive operator committed to responsible diving practices, particularly regarding fish feeding.
• Listen carefully to the dive briefing and follow the instructions of your dive guide.
• Maintain neutral buoyancy to avoid disturbing the coral and marine life.
• Respect the marine environment; do not touch or harass any animals.
• Consider using reef-safe sunscreen to protect the delicate coral ecosystem.
• Bring an underwater camera to capture the incredible sights, but be mindful of your distance from the marine life.
