Meet the site
Cape Nelson is the basalt headland 11 km south-west of Portland, crowned by the 1884 lighthouse and protected on land as Cape Nelson State Park, and it is the most dramatic diving coast in the far west of Victoria. The Scuba Doctor's Cape Nelson Lighthouse entry is a collective one covering a large number of different dive sites around the cape, from 6 to 36 m, and names a few: Capper's Camp at 5–14 m, Yellow Rock at 5–10 m and Devils Kitchen 1.4 km to the east-north-east, with Flat Rock, the Isabella wreck and Jones Bay recorded separately along the same shore. Visit Portland adds that there are two unidentified wrecks in the area and habitats ranging from sand to kelp forest. The cape's cliffs continue underwater as basalt walls, ledges and boulder slopes dropping steeply into cold, clear water, and the growth on them is the richest on the Portland coast: sponges, ascidians, bryozoans and gorgonians in the shade, kelp on the tops. The Scuba Doctor lists seaweed, catsharks, shrimp, cuttlefish, octopus, nudibranchs, banded morwong, sea sweep, magpie perch, leatherjackets and wrasse, and abalone and crayfish are taken here. Seals from Cape Bridgewater pass along the cape and blue whales feed offshore in the upwelling season.
It is boat diving first and foremost – a long, exposed run from Portland Harbour with the sounder as the guide to structure – and Advanced in the sense that the good sites are deep and the whole cape is exposed. A few shore entries exist, reached by steep clifftop walks with ladders and ropes, and they are for fit, experienced divers on flat days only. No dive charter operates from Portland, so the cape is dived by private boats and by arrangement with fishing charters, and it is correspondingly little known; Portland SCUBA is the source of local advice. For a group with a good boat on an autumn high it offers wall diving to 36 m under a lighthouse on one of the wildest capes in Australia.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Cape Nelson Lighthouse Reef is recorded as Reef in Portland & the West. The listed access is boat. 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.
- 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.
