The Drum and Drumsticks is one of the classic Jervis Bay dives, a cluster of rock stacks off the Beecroft Peninsula around 6 km north of the bay entrance. As McFadyen puts it, the largest rock is the Drum and the smaller surrounding rocks are the Drumsticks. Underwater the site is a multilevel rocky reef from 10 m to 30 m with sponge gardens and soft corals on the deeper rock.

On the north side of the Drum a large cave at 14–17 m has several swim-throughs and is locally known as the Lion's Den – operators say lionfish occasionally appear here, though the name is equally apt for the site's other residents. The rocks are home to a colony of Australian fur seals, which are the main attraction for most visitors: young seals in particular will spin around divers, mimic their movements and nibble fins. Blue groper, wobbegongs, Port Jackson sharks, kingfish and silver sweep complete the cast, and grey nurse sharks are sometimes seen in the marine park's sanctuary zones.

A curious feature is the number of old aircraft bombs lying in front of the cave – McFadyen believes they are dummies – left from the decades when the RAAF and RAN used the area for target practice; the adjacent peninsula is still the Beecroft Weapons Range. They should be treated as potentially dangerous and not touched. The site is within a Jervis Bay Marine Park sanctuary zone where special rules apply. With the TSS Wandra just a few metres away, it offers one of the best two-dive combinations on the NSW coast, provided the swell is small enough for the exposed outer peninsula.

Charters leave from Huskisson (Dive Jervis Bay, Owen Street; boats berthed in Currambene Creek). Private boats launch at the Huskisson ramp in Currambene Creek (the bar can be shallow at low tide), Callala Bay, or Murrays Beach in Booderee National Park; Currarong's ocean ramp gives the shortest run to the outer Beecroft Peninsula when conditions allow. The Drum and Drumsticks are about a 40-minute boat ride from Huskisson, across the bay entrance and north along the outside of the Beecroft Peninsula, or about 15 minutes south from the Currarong ocean ramp.

Anchor off the north side of the Drum for the cave.

The outer Beecroft Peninsula cliffs face east to south-east and take the full force of any south-easterly or easterly swell; the sites are diveable in swell under about 1.5 m and are well sheltered from south-westerly and westerly winds, which make them the go-to sites in winter. North-easterly winds (common on summer afternoons) make the run from Huskisson across the bay entrance rough and cause surge on the northern-facing cliffs. Visibility is commonly 15–25 m and can reach 30 m in winter when clear oceanic water sits against the peninsula.

Currents along the cliffs are usually mild but can run at the bay entrance on a strong tide change. Defence live-firing closures can shut the sea area – check before going.

Descend on the north side of the Drum to the large cave at 14–17 m and explore its swim-throughs, then circle the Drumsticks at 10–20 m. Spend the final part of the dive in the shallows where the fur seals play, staying low and letting them approach. Deeper reef and sand extends to 30 m for divers wanting a multilevel profile.

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. One of the most-requested Jervis Bay dives because of the seals; usually combined with the TSS Wandra.
