Meet the site
Bulk Jetty is an industrial jetty on the eastern shore of Cockburn Sound that Bucket List Diver rates among the prettiest shore dives in Perth, while others see it mainly as a reliable site when everything else is blown out. Both views have a point. The structure is about 250 m long and slopes gently from about 3 m at the shore end to 8.5 m down the centre, with open water to 15 m beyond the end and sides.
The pylons and the debris-strewn seabed give it an odd character; Howies compares the bottom to a moon landing. Among the rubble live some very large sea stars, some up to a metre across, along with blue swimmer crabs, razor clams, mussel clumps and, in places, blue-ringed octopus. The pylons are encrusted with sponges, ascidians and soft growth and hold small reef fish, leatherjackets and old wives, and nudibranchs and other macro life reward a slow search.
The jetty needs solid buoyancy. Nets, ropes and cables lie around the pylons, the bracing sits at head height at the surface, and the silt comes up quickly. Visibility averages about 3 m. There is no dive flag on site, and industrial boat traffic works nearby, so bring your own flag.
Bulk Jetty suits Open Water divers with good buoyancy who want a shore dive on a windy day, and photographers interested in pylon macro and the oversized sea stars. It is a short drive from KGT and the Rockingham sites, so it is easy to combine with them.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Bulk Jetty (Kwinana) is recorded as Jetty/Pier in Perth. 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.
- Lines and obstructions
- Discuss any known entanglement concerns and the suitability of the planned area.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
- Overhead environments
- Ask whether the plan stays entirely in open water. A wreck or cave listing is not permission or training to enter.
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.
