Meet the site
Bald Rock is a rocky reef off the southern side of Great Keppel Island that tops out a few metres below the surface and drops to about 16 m. It is one of a pair of south-coast sites, together with the deeper Hannah Rock, and offers a more invertebrate-rich dive than the sheltered sandy bays on the western side of the island. The upper reef is covered in plate corals, which give way on the deeper slopes to tube sponges, sea whips and black coral trees. These invertebrates provide homes for small gobies, shrimps and crabs, and the reef as a whole supports a good population of tropical fish. Batfish are a feature and often hover in small groups off the edge of the reef. Wobbegong sharks rest under ledges and among the plates, turtles are regular, and nudibranchs are common on the sponges. The combination of moderate depth and plenty of structure makes it a good site for photographers who want both macro and reef scenes on one dive. Because it faces the prevailing wind, Bald Rock is dived only when the south coast is calm, so it sees relatively few divers. It suits Open Water divers who are comfortable with a little current, and it makes a good second dive after Hannah Rock when both are visited on the same trip. As with all the Keppel reefs, the inshore setting means visibility is usually moderate, typically 8-15 m, so the best way to enjoy the site is slowly, looking closely at the whips and sponges rather than hoping for long vistas.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Bald Rock (Keppels) is recorded as Reef in Capricorn Coast & Keppel Islands. 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.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- 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.
