Best tide state to fish Alcoa Jetty (Kwinana)
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.
What anglers target here
Anglers fishing Alcoa Jetty (Kwinana) typically time sessions around the tide for pink snapper, mulloway (jewfish), australian herring, tailor, and skipjack trevally (skippy).
