Boat-accessed twin-bommie arch dive off Port Macquarie
Boat-accessed twin-bommie arch dive off Port Macquarie
Cod Hole is a relaxed boat dive off Port Macquarie built around two coral bommies joined by a natural arch. It rewards a slow circuit through the arch, the bommie tops, and the scattered reef around them, with soft coral, sponge cover, and plenty of small life in the cracks and overhangs. The site suits beginner-friendly scuba and especially macro photography when conditions are settled.
Site Conditions
Safety Notes
Treat the natural arch as an overhead feature and keep wildlife awareness around sharks and large reef fish.

Boat access only.
Community notes to help plan your visit.
Scuba Diving
Beginner-friendly boat dive with a natural arch, shallow bommie tops, and plenty of time to work the reef.
Freediving
Not a primary freedive site; the arch and reef features are better suited to scuba.
Snorkeling
The main features sit below the surface, so snorkeling is secondary to scuba.
