Plantation Point is a grassy reserve on a low rocky point between Vincentia and Huskisson, flanked by Barfleur and Nelsons beaches on the western shore of Jervis Bay.

Underwater, the rocky reef around the point drops gently to sand and seagrass at up to about 10 m. The seagrass and weed are the key habitat: weedy sea dragons, pipefish and cuttlefish are reported, octopus hunt among the rocks, and rays and luderick are common. At night the seagrass comes alive with crustaceans and cephalopods, which is why the site is favoured for night dives. Visibility is moderate – typically 5–15 m – and drops after rain when nearby creeks discolour the western shore.

The entry is easy from the beach, the depth is shallow and the reserve has picnic tables, barbecues and a playground, making it a practical training site and a pleasant place for non-diving companions. The main hazards are chop in strong north-easterly winds and occasional small boats and kayaks, so tow a float. Scuba-specific published documentation is limited, so data confidence is moderate. It lies within the Jervis Bay Marine Park. For night dives, a primary and backup torch and a shore marker light make navigation back to the beach easy. Water temperatures range from about 15 °C in late winter to 23 °C in late summer, so a 5–7 mm wetsuit is sensible for anything longer than a quick summer snorkel, and a hood helps from June to October.

Jervis Bay is about 2.5–3 hours south of Sydney via the M1 and Princes Highway, turning onto Jervis Bay Road at Falls Creek. From Huskisson or Vincentia follow the signs in Vincentia to Plantation Point Reserve and park there (picnic tables, barbecues, playground). Walk a short distance to the beach beside the point and enter from the sand, then swim out along the rocks.

It is only about 5 minutes by car from the Huskisson dive shops.

Inside Jervis Bay the water is sheltered from ocean swell, but the bay is big enough for wind chop: strong north-easterlies (summer afternoons) make the western and southern shores choppy, and southerly or westerly winds affect the northern shore less. Diving is possible on most days of the year at one shore or another. Visibility is usually 8–15 m, better in winter, and drops after heavy rain when Currambene Creek and Moona Moona Creek flush tannin water into the bay.

Tides are small but high tide gives better visibility at the beach entries.

Enter beside the point, follow the rocky reef around the point at 3–8 m, then drift back over the seagrass looking for sea dragons, pipefish and cuttlefish.

No scheduled guided shore dives; Dive Jervis Bay and other Huskisson operators hire gear and give site advice, and occasionally run training or snorkel sessions. Its proximity to Huskisson makes it a convenient training and night-dive site.
