Meet the site
The south-eastern tip of Kanowna Island is the deep wall of the Anser Group, and Scuba Doctor rates it, with Skull Rock and South East Point, in the Deep/Technical class of Prom dives. The listing describes a wall that plunges steeply to the bottom at 55 metres, with plenty of boulders, caves and swim-throughs to explore, current swept, facing south-east into the often wild seas of Bass Strait. The wall is granite, dropping in sheer faces and stacked blocks from the kelp line to a boulder floor at 55 m, and the gaps between the blocks form caves and swim-throughs at several depths. Because the site takes the full force of the swell and the tidal stream between the islands and South Point, the growth is the richest kind of exposed-reef cover: dense sponge gardens, yellow zoanthids, gorgonians and sea whips angled into the current, soft corals and jewel anemones, with crayfish deep in the ledges. Fish life is described as prolific – clouds of butterfly and barber perch, sweep, bullseyes in the caves, boarfish and morwong on the ledges, with kingfish and salmon passing in the blue – and the fur seals from the colony on the other side of the island follow divers along the wall. The depth and the current make this a dive for very experienced divers, ideally with nitrox or technical gases and a live boat, and only on a day of complete calm at slack water; it is a site that may see a handful of divers a year. For those divers it combines everything the southern Prom offers – big walls, big fish life, seals and 25 m visibility – on one corner of one island, with the added interest of caves and swim-throughs that the neighbouring seal sites lack. The seal-colony vessel exclusion zone and marine national park rules apply as for the rest of Kanowna.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Kanowna Island, South East is recorded as Wall in Wilsons Promontory. 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.
- 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.
- Lines and obstructions
- Discuss any known entanglement concerns and the suitability of the planned area.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
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.
