Meet the site
Pebbly Beach is rated 7 out of 10 by the Marine Life Network guide as an attractive shore dive by day or night. The rocky bottom reaches 10 m near shore in thick brown algae, extends to 15 m about 20 m out, and green algae become common deeper. Spires rising to 6-7 m are covered in marine life, with deeper spires in 15 m. Numerous species of nudibranch, cup sponges, zoanthids and basket stars live here, with butterfly perch, large long-snouted boarfish, luderick and the usual Bass Strait reef fish. The Leven Scuba Club includes Pebbly Beach in its Rocky Cape sites. 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.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.

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.
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.
