The Docks is Jervis Bay's most popular dive site and a favourite with newly certified divers. The name is obvious from the water: the site lies beside coastal infrastructure on the northern shore of the bay inside Point Perpendicular. The reef is close to shore, dropping through kelp beds and boulders to sand at a maximum of about 21 m.

What makes The Docks special is the number of features packed into a small area. Double Decker Cave consists of two cavities stacked one above the other. The Vertical Swim-through is a tunnel that descends and then turns horizontal. Long Cave runs beneath an enormous rock, Deco Rock has its own cave, and Slot Cave (described separately) cuts into the cliff. Between them are swim-throughs, kelp and scattered sponge gardens where ascidians, sea squirts, gorgonians and sponges show vivid colours under torchlight.

Life is excellent. Eastern blue devilfish (Bleeker's devilfish) hide in the caves, common (weedy) sea dragons forage in the kelp, eastern blue groper follow divers, and bull rays, giant cuttlefish, wobbegongs and snapper are regular. Rarer finds include harlequin ghost pipefish and red indianfish, and tropical visitors appear in late summer. The site is within a Jervis Bay Marine Park sanctuary zone, so nothing may be taken. Visibility varies with sea state and rainfall. Its shallow depths, protection and variety make it ideal for training and photography, and experienced divers still return for the macro life and the caves. Night dives here, when operators run them, reveal octopus, crabs and sleeping fish tucked into the swim-throughs.

Charters depart Huskisson (Dive Jervis Bay; boats in Currambene Creek), and private boats launch at Huskisson, Callala Bay or Murrays Beach. Cross the bay north-east towards the Beecroft Peninsula shore; The Docks lie on the northern side of the bay inside Point Perpendicular at 35° 04.923' S 150° 47.755' E, about 15 minutes from Huskisson. The reef does not extend far from shore, so charter boats anchor extremely close in; larger vessels use the sand to the south and smaller boats sit near Deco Rock.

The northern shore of Jervis Bay is sheltered from all ocean swell except a large south-easterly rolling in through the entrance, and it is protected from northerly and north-easterly winds by the Beecroft Peninsula, which makes it the standard summer venue when afternoon nor'easters roughen the outer coast. Strong southerly and south-westerly winds blow across the bay and make the northern shore choppy and the crossing from Huskisson wet. Visibility varies considerably with sea state and rainfall – typically 8–20 m.

Tidal currents are weak except near Point Perpendicular and the entrance.

From a small boat near Deco Rock, work through the caves – Double Decker Cave, the Vertical Swim-through, Long Cave, Deco Rock Cave and Slot Cave – then follow the sand edge back while ascending. From a larger boat on the sand, follow the reef edge east or west and ascend gradually on the return.

Dive Jervis Bay (Huskisson; boats Avalon and Genesis) runs double boat dives most days, and Deep 6 Diving Jervis Bay / other Huskisson operators also visit; site chosen on the day according to swell and wind. The Docks is the most frequently dived site in the bay and the standard training and new-diver dive.
