What fish can you catch at Semaphore Jetty?

The mainstays are yellowfin whiting in the summer gutters, tommy ruff under the lights after dark, and yelloweye mullet and small salmon year-round. Garfish and southern calamari belong on that list in a normal season but are both closed to recreational fishing in Gulf St Vincent from 1 May 2026. Blue swimmer crabs come into drop nets through summer, and night anglers occasionally pick up school mulloway, gummy sharks and rays.

Do I need a fishing licence to fish Semaphore Jetty?

No. South Australia does not require a general recreational fishing licence, so you can fish the jetty without one. You still have to follow PIRSA size, bag and boat limits and any closures — southern calamari and southern garfish are both shut in Gulf St Vincent, and snapper is shut across the gulf zones until 30 June 2027.

Can you catch squid and garfish at Semaphore right now?

No. Under the algal-bloom recovery measures, southern calamari has been closed to all recreational and charter targeting, take and possession across Gulf St Vincent, Spencer Gulf and the Kangaroo Island zone since 1 May 2026, and southern garfish closed to recreational fishing in Gulf St Vincent on the same date; PIRSA has published no end date for either. King George whiting stay open here all year — the annual 1 March to 30 June spawning closure covers mapped southern-gulf waters, not the metro beaches.

Can you catch snapper at Semaphore Jetty?

No. Snapper fishing is closed across Gulf St Vincent — including all metro waters — for both take and catch-and-release until 30 June 2027. Snapper is only open in the South East Fishing Zone, east of the gulf boundary at the southern tip of the Fleurieu Peninsula. They were historically caught off the jetty, but you cannot legally target them here now.

When is the best time to fish Semaphore Jetty?

Summer, roughly November to March, is the peak — yellowfin whiting run the inshore gutters on a rising tide and the crabs are in the nets. For garfish and tommy ruff, an after-dark session under the jetty lights works all year. Mornings and the calm window after the afternoon sea breeze drops are the most comfortable times on the exposed deck.
