Port Rickaby is a small holiday and fishing settlement on the west coast of Yorke Peninsula, about halfway between Port Victoria and Point Turton, and its old jetty once served ketches loading grain from the surrounding farms. It is not documented in the dive-shop or SDFSA site lists and is included here because the regional brief names it. The jetty stands over shallow sand and seagrass, with typical depths of 2-5 m.

The piles support sponges, ascidians and algae, and the seagrass meadows of this coast are rich nursery grounds, so snorkellers and divers can expect juvenile King George whiting, garfish, tommy ruff, blue swimmer crabs and stingarees, with nudibranchs, small crabs and occasional seahorses and pipefish on the piles. Southern calamari visit the jetty at dusk. Like Port Victoria to the north, the jetty should have its best visibility on easterly days, when the wind is offshore.

Westerlies bring chop and silt. Port Rickaby's appeal lies in its quiet setting and easy access for anyone staying in the caravan park. Divers seeking a quality jetty experience on this coast should head to Port Victoria or Point Turton.

Data confidence is low; treat the details as indicative.

From Adelaide drive about 200 km (2.5 hours) to Minlaton, then about 18 km west to Port Rickaby; or 30 km south along the coast from Port Victoria. The jetty is at the foreshore beside the caravan park and small boat ramp. Park at the jetty head and enter via the steps or the beach at mid to high tide.

The west coast of Yorke Peninsula faces Spencer Gulf, so westerly, south-westerly and north-westerly winds blow onshore, raise chop and stir the sediment, while easterly winds blow offshore and give the flattest, clearest water – local advice at Port Victoria is that visibility is best when a strong easterly is blowing. The upper parts of the coast get little ocean swell, but the southern end (Corny Point, Point Turton's outer coast) and the western side of Wardang Island feel south-westerly swell that wraps into the gulf. Tides are modest but noticeable in the channels.

Summer sea breezes swing south-westerly in the afternoon, so mornings are best.

Snorkel or dive along the piles to the end, check the seagrass fringe for pipefish and seadragons, and return.

No operator; occasionally snorkelled or dived by holidaymakers.
