Meet the site
Inner Point Perpendicular is the protected, inside face of the great northern headland of Jervis Bay, at the point where the cliffs turn north at right angles. A large pyramid-shaped rock marks the spot, which is why it is also known as Pyramid Rock (not to be confused with the Pyramid Rock on Bowen Island) and as Fish Rock.
The dive runs from sand at 32 m, where a prominent reef and some small rocks begin, up the reef face through 20–25 m and into the shallows at 5 m against the cliff. The cliff is undercut by a number of caves, one of which extends back a considerable distance to the east about 50 m inside the corner. Yellowtail, silver sweep, one-spot pullers and girdled parma are the common fish, and at times quite large schools gather around the pyramid. The reef supports the sponges and encrusting growth typical of the bay entrance.
McFadyen rates it as suitable for all experience levels: the depth can be tailored to the group, the caves are in the shallows, and it is especially good in north-easterly winds when the outer sites are rough. On an incoming tide the site becomes a gentle drift dive along the reef. It is commonly used as a second dive after one of the deeper outer sites such as The Arch or the Point Perpendicular Sponge Gardens, which lie just around the corner. Divers should keep an eye on boat traffic entering and leaving the bay close to the headland.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Inner Point Perpendicular is recorded as Reef in Jervis Bay. The listed access is boat. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
- Overhead environments
- Ask whether the plan stays entirely in open water. A wreck or cave listing is not permission or training to enter.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
