Meet the site
North Point Hole is a small, little-documented neighbour of North Point Reef. Marinelife.org.au describes it simply as a cavern in the reef extending down to the seabed at 26 m and 'full of marine life', with depths of 18-26 m. It lies only a short distance from the North Point ravine, so boats that have found one can find the other.
As with other Rottnest caverns, the interest comes from the limestone itself - an opening that drops through the reef to the sand - and from the fish that pack into the shade: bullseyes, old wives and sweep in the darker parts, buffalo bream and wrasse around the entrance, and western rock lobster and cuttlefish in the cracks. The depth brings in larger fish such as dhufish and samson fish at times.
Because published information is thin, divers should treat it as an exploratory dive and go with someone who knows it, or use it as an extension of a North Point Reef dive on a calm day. It suits Advanced divers with nitrox and good buoyancy. Note that marinelife.org.au lists the same coordinates for Cigar Reef, so check positions with a sounder before committing.
On a flat day with 20 m or more of visibility, looking up from the bottom of the hole toward the surface is a striking view, and the combination with North Point Reef makes for a well-rounded deep dive. Keep the group small inside the cavern and carry a torch to see into the darker recesses.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
North Point Hole is recorded as Cave/Cavern in Rottnest Island. The listed access is boat (day trip). 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.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
- 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.
Questions, answered
Is North Point Hole suitable for my certification?
The record lists Advanced Open Water. That does not establish suitability for every route or day. Share your training, recent experience and equipment needs with the operator and ask about the specific proposed dive.
Can I book North Point Hole through YouDive?
YouDive is an independent research directory. Contact an operator directly to confirm whether it currently runs the trip, the inclusions and the booking terms.
