Meet the site
Point Gellibrand is the southern tip of the Williamstown peninsula, the site of the Timeball Tower, the old naval battery and the Coastal Heritage Park, and along its Port Phillip face the shore is a continuous run of basalt ledges and rock pools formed by the Newer Volcanics lava that flowed down to the bay from the west. The rock pools at Battery Road, also called the Bunbury Rockpools, are the entry. The first metres are shallow, uneven basalt full of pools and gullies, and the ground then deepens gradually into a broad reef of ledges, boulders and undercuts in 3-5 m before running out onto sand. It is not a big or deep site, but it is unusually rich for somewhere ten minutes from the West Gate Bridge. The basalt is coated with encrusting sponges, tubeworms, mussels and algae, and the ledges shelter a surprising number of fish for an inner-bay reef: leatherjackets, wrasse, zebrafish, dusky morwong, blennies, cardinalfish and juvenile snapper, with rays and flathead on the sand. Its reputation among photographers rests on nudibranchs; large, colourful sea slugs are found in numbers on the undersides of the ledges and it is regarded as one of the most rewarding macro sites close to the city. Octopus, decorator crabs, cushion stars and urchins round it out. The entry over slippery basalt at high tide is the only real difficulty, and shipping wash from the channel can surge across the platform, so the site is best on a calm day with a north-westerly. The wreck of the Albert William lies 450 m to the east for those interested. With free parking, a playground and the heritage park behind it, it is a pleasant, low-key western-suburbs dive.

Point Gellibrand is recorded as Shore/Rock Platform in Melbourne & Port Phillip Bay. The listed access is shore. 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.
- 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.
