About Julian Rocks - Cod Hole
Julian Rocks - Cod Hole is an advanced Julian Rocks dive on the northern side of Nguthungulli where a small cave and overhang system cuts into rock at moderate depth and attracts some of the site's biggest winter wildlife encounters. The draw is not wide-open reef cruising but a compact high-interest feature dive. Divers work around the cave mouth and surrounding rock for grey nurse sharks in season, large moray eels, wobbegongs, rays, and passing pelagic fish, while managing the site with the extra care that overhead structure and exposed current demand.

Scuba Diving
An experienced-diver site featuring a small cave starting around 15 m and descending to about 21 m.
