Meet the site
Lemon Rock is a granite islet at the mouth of Wineglass Bay and one of the more remote dives on the east coast. The Marine Life Network guide rates it 6 out of 10 and describes a weedy shelf that drops rapidly into 30-40 m, with bull kelp and cray weed in the shallows and clouds of butterfly perch on the deeper face.
The guide notes that the rock supports delicate marine life, including sea daisies and other invertebrates, and that crayfish are present. A slight current runs past the rock, which helps the filter feeders, and schools of fish and marine mammals - seals and dolphins - are possible. The granite here is the same as the rest of the Freycinet coast, so expect boulders, vertical faces and cracks rather than ledges.
Lemon Rock is best thought of as an expedition dive. It is well away from any ramp, there is no dive operator on the peninsula, and the rock is exposed to the open Tasman Sea. The reward is a genuinely rarely dived site with clear oceanic water and a steep wall. It pairs with a shallow second dive or snorkel in Wineglass Bay itself.
It suits experienced, self-sufficient divers with a capable boat and skipper, deep training and an understanding that help is a long way off: the nearest chamber is in Hobart, several hours away. Documentation is limited to one regional guide, so divers should expect to explore.
Some context helps set expectations for all Freycinet diving. The peninsula's pink granite continues under water as rounded boulders, cracks and steep faces, and the area sits where the warm East Australian Current meets cooler southern water, so species lists mix typical Tasmanian fish with more northern visitors. Over recent decades warming water and grazing by the long-spined sea urchin, which has spread south from New South Wales, have thinned kelp beds along the east coast, and descriptions written in the 1990s may not match what you find today.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Lemon Rock (Wineglass Bay) is recorded as Island in Tasmania East Coast. 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.
- 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.
- 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.
