The Cod Hole on Ribbon Reef 10 is one of the world's most famous dives, known for its gigantic potato cods.

The Cod Hole is one of the best known dives in the world and it is visited by many liveaboard cruises out of Cairns and Port Douglas. It is famous because here you can dive with huge cods that are accustomed to divers and will come very close. The famous giant potato cod is still fed by dive masters. Dive down to the sandy floors area between the bommies, where you will see the fish feeding from beneath. Other marine species common in these waters are leopard morays and Maori wrasse, but it is the huge cods that make this site different from others in the Ribbon Reef area.
