Alcoa Jetty in Kwinana is one of the few spots in Cockburn Sound where you can access genuinely deep water from the shore. The industrial jetty pylons create massive structure in deep water, and big pink snapper hold around the end of the jetty and along the pylon line. It's not pretty, but it's productive.

Fish heavy rigs with fresh bait (whole squid, mulies, or octopus) tight to the pylons for snapper. The deeper water means you need enough weight to hold bottom in the current. Dawn and dusk sessions are most productive, but snapper also bite well at night. Berley helps draw fish to your section of the jetty.

Pink snapper (the main target, big fish around the pylons), mulloway (at night, deep water), herring, skippy, tarwhine, tailor, squid around the pylons at night, and summer kingfish when warm water pushes through.

Heavy tackle is needed here — this isn't light-tackle territory. Don't fish near active loading or bulk-carrier movements; security will move you on. Don't leave gear unattended.

Access to Alcoa Jetty can be restricted — it's an industrial facility and access arrangements change with operator policy. Verify current access before driving out via the operator or community angler groups. When access is open, sealed approach roads lead to a working industrial jetty. No public toilets, cafes or amenities; this is not a destination for casual fishing. The drive from central Perth is around 35 minutes via Kwinana Freeway.

South-facing position inside Cockburn Sound. Fishes well in most weather thanks to the sound's geography and the jetty extending into deeper protected water. Easterly mornings are calmest. The deep water around the jetty pylons creates substantial current on tide changes; gear up for it. Cockburn Sound water clarity varies with industrial activity and weather; reduces after heavy rain. Bulk-carrier wash is constant during loading periods.

Pink snapper in Cockburn Sound is closed 1 August – 31 January for the spawning aggregation — DPIRD compliance officers operate in the area. Industrial facility with active vessel movement and loading operations; respect security boundaries and signage. Heavy tackle, deep water and current mean falls and tackle injuries are real risks; gear up safely. Cockburn Sound algal blooms periodically affect the area; check DPIRD advisories.

Access can be restricted — it's an industrial facility. Verify current access arrangements before committing to the drive. Some periods see open public access; others have restrictions. Check with the operator or community angler groups for current status.

Yes when access is permitted and outside the Cockburn Sound spawning closure (1 August – 31 January). The deep water around the pylons holds quality snapper that you can't reach from most metro shore spots. Heavy gear, fresh bait, and patience are the formula.

Heavy tackle. 10–15kg setup with 30–50lb braid, 60–80lb leader, 6–8 oz running sinkers, 6/0 hooks. Whole fresh squid, mulies or octopus baits. Light gear gets snapped or swept by the current; this isn't a finesse fishery.

You can fish but cannot target or retain pink snapper between 1 August and 31 January. Other species (herring, tailor, squid) are fair game year-round. Compliance officers are active during the closure; release any incidental snapper immediately.
