Crocodile Head is a deep site on the Beecroft Peninsula, about two nautical miles north of the Jervis Bay entrance and reached by boat only. It bottoms out near 30 m and is catalogued as an advanced dive, described as one of the best deep dives in the area, with current the condition to watch.
Where it is and how deep
35.0700° S, 150.8300° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
The run out is about two nautical miles north of the bay entrance along the Beecroft Peninsula, and there is no shore option here: the site is boat access only. Depth reaches roughly 30 m, which puts the dive at the bottom of the recreational range and keeps no-stop time short. The directory that catalogues it rates it as one of the best deep dives in this part of the bay, and as advanced rather than intermediate.
Current is the variable that shapes the dive, and the listing flags it specifically with a warning to take care of it. On a 30 m site that argues for a prompt descent, working into any flow at the start and letting it carry you back towards the pick-up, with a delayed surface marker buoy ready if the ascent ends away from the boat. Beyond the depth, the difficulty rating and that current note, nothing is published about the terrain or the marine life, so the briefing on the day is the real description of this site.

Know before you go
- Current: the only condition the listing calls out, with a warning to take care of it. Descend promptly on the line and carry a delayed surface marker buoy.
