The Boulders is exactly what its name promises: a field of huge boulders midway along the eastern, ocean-facing side of Bowen Island. McFadyen describes the site as having plenty of nooks and crannies for fish to hide in, created by the jumble of massive rocks, with depths from about 12 m to 24 m.

The gaps and overhangs between the boulders shelter blue groper, leatherjackets, wobbegongs and schooling fish, and the rock surfaces carry sponges and encrusting growth typical of the Jervis Bay entrance. Because the site faces the open sea, visibility can be excellent when clear oceanic water is pushed against the island, and pelagic visitors such as kingfish occasionally pass by. The boulder landscape encourages slow, meandering exploration rather than a fixed route.

McFadyen rates it suitable for both beginners and experienced divers: the depth range is moderate and the site is easy to navigate by keeping the island on one side. Its exposure is the main limitation – the eastern face of Bowen Island takes easterly and south-easterly swell directly, so it is dived on calm days or in westerly weather. It is less documented than the corners of the island, so detail here is drawn from a brief description plus the general character of Bowen Island reefs; confidence is moderate. The waters are within Booderee National Park and a sanctuary zone, and landing on Bowen Island is not permitted. It is often paired with the more sheltered North Bowen Island or The Nursery as a second dive, allowing divers to compare the ocean face with the protected inner corner of the island in a single trip.

Charters depart Huskisson (Dive Jervis Bay; boats in Currambene Creek), about 15–20 minutes across the bay to Bowen Island. Private boats can launch at the Murrays Beach ramp in Booderee National Park (park entry fee; ramp faces Bowen Island, 5 minutes away) or at Huskisson/Callala. Run out of the bay entrance and south along the eastern (ocean) side of Bowen Island to its midpoint (about 20–25 minutes from Huskisson).

Anchor on the boulders in 15–20 m.

Bowen Island shelters the southern side of the Jervis Bay entrance. The inside and north-western corner (Nursery, Aztec, North Bowen) are protected from southerly swell and are often the only diveable sites when big southerlies close the outer coast, although waves can break on the points in large seas. The eastern and southern faces are exposed to south-easterly and southerly swell and want under about 1.5 m.

An outgoing tide can produce strong current around the island's points. Visibility typically 10–20 m. The eastern side faces the open sea and needs small swell, ideally with westerly winds.

Descend onto the boulders and meander among them at 15–20 m, peering into the gaps for fish, then drift along to the 24 m sand edge and back up towards 12 m before returning to the anchor.

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.
