Alcoa Jetty (Kwinana)

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, and as of August 2026 it's not reachable on foot either — the coal wharf is off limits to land-based anglers and port security moves people off the old Kwinana Beach jetty. The pylons are a boat fishery.

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. The wharf itself is closed to land-based anglers, so this is a boat plan; from a boat, stay outside the berth exclusion and clear of vessel movements.

The coal wharf at Alcoa Jetty is reported off limits to land-based anglers — a secured industrial berth rather than a public jetty, with port security moving anglers off the old Kwinana Beach jetty nearby; no operator statement is published either way, so treat it as a boat fishery. 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. Wind off the land, water like glass — until it isn't. The deep water around the jetty pylons creates substantial current on tide changes; gear up for it. Cockburn Sound water clarity varies with weather and reduces after heavy rain. Shipping movements have thinned since Alcoa curtailed the Kwinana refinery in June 2024 and announced its permanent closure in September 2025, with decommissioning running through 2026 — the port and rail facilities stay operational, so vessel traffic continues but not at the old loading tempo.

Pink snapper in Cockburn Sound is closed 1 August – 31 January for the spawning aggregation — DPIRD compliance officers operate in the area. Secured industrial berth: the wharf is closed to land-based anglers and security enforces it. Vessel movements continue through the refinery decommissioning; respect exclusion 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.

Effectively no. The coal wharf is reported off limits to land-based anglers and port security moves people off the old Kwinana Beach jetty nearby; no operator statement is published either way, so treat it as a boat fishery. The pylon structure fishes well, but from a boat. For a shore session in the same water, walk to Challenger Beach or drive to Palm Beach Jetty in Rockingham.

Yes, from a boat and outside the Cockburn Sound spawning closure (1 August – 31 January). The deep water around the pylons holds quality snapper. It is not a land-based option — the wharf is closed to shore anglers. 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.

From a boat you can fish but cannot target or retain pink snapper between 1 August and 31 January — the Cockburn and Warnbro Sounds closure binds shore and boat fishers alike. Other species (herring, tailor, squid) are fair game year-round. Compliance officers are active during the closure; release any incidental snapper immediately.
