Cod Hole is the famous Great Barrier Reef dive site where potato cod have been fed by divers.
The site lies near Ribbon Reef 10 in the northern Great Barrier Reef. It became known for close encounters with large potato cod, also called potato grouper, which can grow to impressive sizes and are naturally curious around divers.
Feeding wild animals can alter their behaviour, so the site’s reputation belongs to a particular history of tourism and management rather than representing normal reef conditions. Modern marine tourism increasingly emphasizes controlled interactions and wildlife protection.
Cod Hole is sometimes mistaken for a general nickname for any reef site with large fish. It is a specific dive location associated especially with potato cod and the Ribbon Reefs.
