Cod Hole is a northern Great Barrier Reef dive site in the Ribbon Reefs, famous for its potato cod. It is a remote boat-diving destination, not a shore dive or a standard outer-reef day trip from Cairns.
Choosing a trip
Spirit of Freedom advertises a three-night Cod Hole and Ribbon Reefs itinerary from Cairns. Its seven-night itinerary combines those reefs with the Coral Sea. A Cod Hole trip does not automatically include Osprey Reef or North Horn; check the named route and departure before booking.
The operator recommends the three-night trip for Open Water to experienced divers, with its published guidance referring to at least 10 ocean dives, including five in the previous 12 months. The longer Coral Sea itinerary has more demanding experience recommendations. Ask the operator to confirm your eligibility for the complete trip, not just this single site.
Marine life and dive conditions
The potato cod are the main attraction, alongside reef fish and coral habitat. Encounters vary. Follow the crew’s wildlife briefing, maintain buoyancy and avoid touching or chasing animals.
Depth, current and visibility depend on the exact dive plan and conditions. Older descriptions calling the site easy for everyone should not replace the operator’s assessment.
Planning from Cairns
Use our Cairns diving guide and Great Barrier Reef travel guide to compare northern liveaboard routes with shorter reef trips. Weather can alter the actual sites visited.
Itinerary guidance checked 13 October 2026 against Spirit of Freedom’s published three-night and seven-night trip listings.
You can dive Cod Hole all year long. Access: Boat. See the map of Cod Hole on the right for the exact location.

Diving Reviews for this region
Great Barrier Reef
The Great Barrier Reef is a long reef system off Queensland, not a single dive site. Choose Cairns for the largest range of reef boats and northern liveaboards, Port Douglas for Agincourt day trips, Townsville for MOUA and Yongala access, or the Whitsundays for island holidays and Hardy Reef.
Liveaboard Reviews in Great Barrier Reef
MV Ocean Quest
OceanQuest is Divers Den’s reef-based catamaran, reached by a fast transfer boat from Cairns. Choose one to five nights on the outer reef, or a separate four-night Ribbon Reefs expedition during minke whale season.
Coral Sea Dreaming
Coral Sea Dreaming takes just 12 guests on an overnight Great Barrier Reef trip. Choose a double cabin or shared bunk, with guided diving and a canopy-covered social area where everyone soon gets to know one another.
Spirit of Freedom
The 37-metre Spirit of Freedom offers scuba diving cruises to the Great Barrier Reef, the Coral Sea and the northern reefs. Its current programme includes three-, four- and seven-night trips as well as longer-range special expeditions.

Cod Hole is amzing to see the huge Groupes. The coral is nice too.
Excellent dive. Very easy with lots of the large cod qnd several white tip sharks napping on the bottom. I was on the Spoilsport (Mike Ball liveaboard) and had a fantastic time. It would be an appropriate dive for anyone from beginner to advanced.
