Cod Hole earns its name from the giant potato cod that patrol this Western Australian reef with remarkable confidence around divers. Visibility runs from 25 to 60 metres in these clear waters, meaning you'll often spot the big animals well before they reach you. The reef drops to 30 metres, though most of the action happens in the shallower sections where Maori wrasse, turtles, and schools of trevally, mackerel, and tuna move through. Strong currents are the main variable here, so dive timing matters. Between September and November, hammerhead sharks, reef sharks, manta rays, and even humpback whales become realistic sightings. Boat charter access only.

Plan your dive around slack water to manage the strong current, and brief your group on shark awareness before entering since hammerheads and reef sharks are a genuine presence at this site. September through November gives you the best shot at the larger pelagics including manta rays and humpbacks.
Access is only possible via multi-day liveaboard charters departing from Broome. The journey to the Rowley Shoals takes approximately 12 hours.
The primary hazard is the strong and variable tidal current. The outer reef walls are extremely deep. While sharks are common, they are not noted as being aggressive.
