Meet the site
Bunker Bay sits on the northern tip of Cape Naturaliste, where Geographe Bay meets the Indian Ocean. Marinelife.org.au describes a dive and snorkel from Shelley Beach to a small rock about 60 m offshore, with reef on its seaward side in about 5 m, and good snorkelling and diving along the shore toward West Point. It lists stingrays, bream, sweep, moonlighters, stripeys, coralfish, red-lipped morwong and prettyfish, a notable mix that reflects the warm Leeuwin Current reaching the cape. Meelup Park notes Bunker Bay's white sand and summer swimming.
The granite reef here supports sponges, weed and some corals, and the diversity of small reef fish is good for such a shallow site. The short swim makes it accessible to snorkellers and shore divers of all levels in calm conditions, while the shoreline toward West Point gives longer dives.
Bunker Bay is also within the Ngari Capes Marine Park, which has a Cape Naturaliste sanctuary zone nearby - check current zoning maps before fishing or collecting.
Geographe Bay faces north, so Cape Naturaliste blocks most of the prevailing south-westerly swell and sea breeze that close the ocean coast; that shelter and the warm Leeuwin Current make the Dunsborough shoreline one of the most reliably diveable stretches of the South West, and winter north-westerly storms are the main thing that shuts it down.

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.
