Klein Point is an industrial jetty rather than a recreational one. It serves the large limestone quarry on the cliffs south of Stansbury, which has supplied limestone for cement manufacture in Adelaide for decades, and ships and barges load here via a conveyor running out along the structure. The jetty stands in shallow to moderate depth, roughly 3-10 m, over a sand, rubble and seagrass bottom typical of this stretch of Gulf St Vincent.

In principle, any long-standing structure in these waters attracts the same encrusting community found at nearby Edithburgh and Wool Bay – sponges, ascidians, bryozoans and soft corals on the piles, with nudibranchs, crabs, leatherjackets, magpie perch, trevally and the chance of seahorses or leafy seadragons in the adjacent weed. However, documentation of Klein Point as a dive site is very thin. It does not appear on the Scuba Divers Federation of SA or major Adelaide shop site lists, and there is no published site guide describing its layout underwater.

What is clear is that the land approach is private industrial property, so the jetty cannot be dived as a casual shore dive like its neighbours. Divers with their own boat out of Stansbury occasionally drop in on quiet days, but ship loading and limestone dust in the water make it an unpredictable site, and it offers nothing that the easily accessed jetties at Wool Bay, Edithburgh or Stansbury do not. Anyone considering it should first contact the quarry operator for permission and check that no vessel is scheduled; most divers will be better served by Wool Bay, 4 km further south, which offers leafy seadragons and an easy public entry.

Klein Point is reached via the coast road about 4 km south of Stansbury (roughly 205 km from Adelaide). The jetty belongs to the limestone quarry and loading operation, and the land approach is private and fenced, so there is no walk-in shore entry. The only practical approach is a small boat launched at the Stansbury ramp (about 10 minutes' run south), anchoring clear of the jetty and never diving while a vessel is loading.

Confirm current rules with the operator and local shops before attempting a dive.

This coast faces Gulf St Vincent, so onshore easterly, north-easterly and south-easterly winds ruin it: 15 knots from the east stirs the fine sediment and drops visibility to a metre or two, and a strong south-easterly adds chop and surge. Westerly and south-westerly winds blow offshore and give the flattest, clearest water, best after a day or two of settled weather. There is no ocean swell inside the gulf.

Tides are modest (1-2 m, with 'dodge' tides of little movement), but shallow jetties are easier around high water. Autumn is calmest; summer south-east sea breezes build in the afternoon, so dive mornings. Fine limestone dust from loading operations can also cloud the water around the jetty on working days.

If diving from a boat, descend beside the outer section of the jetty, circuit the piles on the sand and return to the anchor. Keep the dive short and stay visible; abandon it if loading begins.

No regular operator; very occasionally dived by locals with boats from Stansbury. Not listed on SDFSA or The Dive Shack site lists.
