What can you catch off Vivonne Bay Jetty?

Huge tommy ruff at night are what it is famous for, with big trevally in winter alongside King George whiting, calamari and garfish. The beach beside the Harriet River mouth adds salmon, mullet, flathead, school sharks and bream to nearly a kilogram, and Point Ellen at the western end gives sweep, salmon and trevally off the rocks.

Can you catch squid at Vivonne Bay?

Yes, and this is the only Kangaroo Island platform where you can. The fishing-zone boundary follows the island's north coastline, so the south coast is outside the Gulf St Vincent and Kangaroo Island zone where calamari and garfish have been closed since 1 May 2026. Here calamari is open at 15 per person with no size limit, and garfish at 23 cm with a bag of 30.

Can you keep snapper at Vivonne Bay?

Yes. The island's south coast sits inside the South East snapper fishery area, so snapper is open at 38 cm with a bag of 5 and a boat limit of 15 while the rest of the state is closed until 30 June 2027. Every snapper kept must be reported through the free SA Fishing app, and you cannot carry it back across the closed zone, so landing it at Penneshaw is not legal.

Is there a boat ramp at Vivonne Bay?

No. There is a rough launch site that depends entirely on the weather and nothing more. The nearest proper facilities are on the north coast, and this is not a coast to improvise a launch on.

Where is the nearest sanctuary zone to Vivonne Bay?

The Seal Bay Sanctuary Zone begins 5.9 km east of the jetty, with no habitat-protection buffer in front of it, so the no-take water starts exactly at the park line. The Seal Bay restricted access zone, where entry itself is prohibited, is about 9 km east. Vivonne Bay itself is outside the marine park, and the fishing is legal right up to that line.
