Meet the site
Bluestone (Blue Rocks) Point, east of Rocky Cape, is rated 6 out of 10 by the Marine Life Network guide as a typical shallow foreshore dive. The bare rocky foreshore drops quickly to an 8 m shelf, and the sandy bottom beyond is cut by long reefs running seaward, with an enticing reef in mid-bay between 10 and 18 m. Large basket sponges, sea fans, lace corals and isolated zoanthid patches grow on the reefs, with luderick, silverbelly, red mullet and barber perch among the fish. It is convenient to the ramp but only worthwhile in moderate weather. Local divers typically combine two or three Rocky Cape and Sisters Island sites in a day, choosing the side of the cape that suits the wind and the state of the tide.
The Rocky Cape and Sisters Island area is, in the Leven Scuba Club's words, the best collection of dive sites on the north-west coast. The quartzite of Rocky Cape - some of the oldest rock in Tasmania - forms gutters, ledges, caves and bommies, and the tidal flow along Bass Strait keeps sponges, gorgonians, sea pens and bryozoans well fed. Michael McFadyen, diving here in February 2008, recorded 18-19 °C water and 20-25 m visibility, figures that surprise divers used to the east coast.
Rocky Cape National Park also protects Aboriginal cave sites and coastal heath above the water, and a Parks Pass is required for vehicles. The nearest hyperbaric chamber is the Royal Hobart Hospital, about four hours' drive away, so conservative profiles and oxygen on the boat are essential.

Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
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.
