Ardrossan Jetty

Ardrossan calls itself the blue swimmer crab capital of South Australia, has a giant fibreglass crab at the jetty entrance to prove it, and the drop-net crowd has never seriously argued. The 1876 town jetty runs about 430 metres east off the red cliffs into upper Gulf St Vincent over seagrass meadows and sand — shallow for hundreds of metres, which is exactly why the crabs, yellowfin whiting and tommies like it. It was closed for most of a year for a full renewal and reopened on 7 August 2026 on new steel piles, so the deck you are fishing is the newest on the peninsula. The jetty is sheltered from the westerlies that blow out the Port Hughes side, and an hour and a half from Adelaide it is the closest serious crab jetty to the city.

Crabs first. Drop nets or hoop nets baited with fish frames — no meat or chicken, that is the rule, not a tip — go over the rail anywhere from the second set of steps out, worked on the rising tide and checked every twenty minutes. On a low tide the rakers walk the flats north of the jetty with a crab rake and a bucket, which is the traditional Ardrossan method and arguably more fun. Tommies are a berley job off the sides on a float rig after dusk. Yellowfin whiting feed in the shallows along the inshore half of the jetty and on the flats either side from spring to autumn — a light running-sinker rig with a small long-shank and a live worm or a surface popper walked across a metre of water both work. Snook and salmon trout hunt the lights and the end after dark on small lures. The end reaches five or six metres of water and is where the occasional school mulloway is hooked on a summer night.

Blue swimmer crabs are the reason most people come, running from about October to April with the bigger males in late summer; the rules are 11 cm across the carapace, bag 20, boat 60, and every berried female back in the water. Tommy ruff hold all year. Yellowfin whiting to 40 cm are a genuine jetty target here from October to March, 24 cm minimum and bag 10 in Gulf St Vincent. Snook and salmon trout work the lights through the warmer months, mullet fill the shallows over autumn and winter, and the odd school mulloway comes off the end on a summer night. Southern garfish and southern calamari were both staples until PIRSA closed them to all recreational take in the Gulf St Vincent and Kangaroo Island zone from 1 May 2026, with no end date published. King George whiting are mostly a boat fish here, 32 cm with a bag of 5, and closed 1 March to 30 June. Snapper — the old-timers' "ruggers" — are closed across the gulf until 30 June 2027, catch-and-release included.

Fish-based bait only in the nets; the fisheries officers know the chicken-neck trick and so does the fine. Measure every crab as it comes up, not at the car. Rake the flats on a falling tide in the morning and you will have the beach to yourself; by mid-afternoon on a January weekend it looks like a gold rush. The caravan park hires crab nets and tubs and has cooking stations, which saves the car smelling of boiled crab for a fortnight. Squid jigs and gar floats stay in the bag until the gulf closures lift — after the 2026 bloom, an Ardrossan calamari fisher told the ABC the gulf's key species were "near non-existent", so the closure is doing a job. Bivalves from the gulf are still under a do-not-eat advisory.

The jetty is at the end of Jetty Terrace below the main street, with a public toilet, picnic area and lawns at the foot and free parking along the foreshore. The renewed deck is concrete, flat and foot-only; the council lists disability access as "contact operator", so check before relying on it. The dual-lane all-tide boat ramp with a pontoon sits in the sheltered harbour by the bulk-loading jetty off Rowe Terrace — launch permits are via the EasyPark app or the Ardrossan Caravan Park, and launching is free statewide until around 1 December 2026 under the algal-bloom fee holiday. The BHP bulk jetty 1.5 km south is port infrastructure with no public access. Ardrossan is about 150 km and 1 hour 45 minutes from Adelaide.

The jetty points east into upper Gulf St Vincent with the red cliffs and the town behind it, so westerlies and south-westerlies come off the land and leave the water calm — the reason divers use Ardrossan when the rest of the peninsula is blown out. Easterlies and north-easterlies blow straight down the gulf onto the deck and are the winds to avoid. The upper gulf has the biggest tides on the peninsula, commonly two to two-and-a-half metres and up to 3.6 m on the springs, which drains the flats a long way out on a low and drives the crab movement; the fortnightly dodge tide flattens both the range and the fishing. Warm, settled summer weather is crab and whiting time; autumn and winter bring mullet, salmon trout and cleaner water.

The inshore half of the jetty stands over barely a metre of water at low tide, which makes a fall onto the bottom a real injury rather than a swim. The flats drain a very long way out and fill again quickly on the big upper-gulf tides — rakers need to keep an eye on the water and the time. Lost crab nets and squid jags litter the bottom under the deck; divers report them and so will your tangled line. The cliff edges along the lookout are unfenced in places. Summer sun and heat on an exposed 400-metre concrete deck call for water and shade. Sharks are not a jetty-deck concern; the tidal flats are a place for reef shoes, not bare feet.

Yes. It reopened on 7 August 2026 after a renewal that ran from September 2025 — new steel piles, crossheads and girders under a concrete deck, part of a $10 million state and council project shared with Edithburgh. Edithburgh's jetty closed for its turn on 24 July 2026.

October to April, peaking in January and February, on a rising tide for the drop nets and a falling tide for raking the flats north of the jetty. Crabs must be 11 cm across the carapace, the bag is 20 per person and berried females go straight back. Fish-based bait only in the nets.

Tommy ruff all year, yellowfin whiting in the shallows from spring to autumn, snook and salmon trout around the lights at night, mullet in the cooler months and the odd school mulloway off the end on a summer night. Garfish and southern calamari are closed in Gulf St Vincent since 1 May 2026 with no end date, and snapper are closed until 30 June 2027.

Not at the moment. Both southern calamari and southern garfish are closed to all recreational targeting, take and possession in the Gulf St Vincent and Kangaroo Island fishing zone from 1 May 2026 under the algal-bloom recovery measures, and PIRSA has not published an end date. Garfish are still open on the Spencer Gulf side at Port Hughes.

No fishing licence — South Australia has none for recreational line and net fishing. Boat launching normally needs a permit via the EasyPark app or the caravan park, but ramps are free statewide until around 1 December 2026 under the algal-bloom fee holiday.
