The seal colony near Steamers Beach, on the ocean side of Booderee National Park, is one of the best places in NSW to dive with Australian fur seals. McFadyen named his mark Alyssa's Playground, and operators call it the Steamers Headland seal colony. Around 30–40 seals use the area, and they are extremely approachable and used to divers – they often come within a foot of a diver's mask, surfacing to breathe and returning again and again. Encounters are best when divers stay still on the bottom rather than chasing them.

The seabed is rocky with many huge boulders accumulated over millennia, and sand at about 25 m. A prominent bommie sits just beneath the surface near the western point of a small bay, a wall drops on the western side, and the reef turns east into shallower flat or sloping rock at 10–12 m below the wave-washed platform. Sponges, sea squirts and sea whips cover the boulders, and ocean sunfish are occasionally seen, suggesting the area acts as a cleaning station. Deep 6 notes that fish life is less abundant than at other sites – this dive is about the seals.

Visibility is normally very good, at least 20 m. The seals are present year-round, but numbers and activity peak in winter, when operators run dedicated seal trips; Deep 6 describes the seals as migrating to the colony south of St Georges Head in winter. The run from Huskisson is long and exposed, so trips depend on the weather. Divers should respect the animals: no touching, feeding or chasing, and give large bulls and hauled-out seals plenty of space.

Charters depart Huskisson (Dive Jervis Bay; boats in Currambene Creek). Private boats can launch at Murrays Beach ramp in Booderee National Park (park pass required), which is the closest ramp to the southern headland. From Murrays run out through the entrance between Bowen Island and the mainland only in flat seas at high tide (boats under 6.5 m), otherwise go around the north of Bowen Island; Run south along the Booderee coast about 5.3 nautical miles from the northern end of Bowen Island to the small bay near Steamers Beach (35° 10.747' S 150° 43.826' E), about 40 minutes from Huskisson.

The prominent bommie just beneath the surface near the western point of the bay marks the site. Reasonably good seas are needed to get there.

The southern headland of Jervis Bay (Booderee National Park's ocean coast) faces east and south-east and takes the full force of southerly and south-easterly swell. These sites need swell under about 1–1.5 m and are best in westerly or north-westerly winds – typically winter – when the cliffs give a lee. North-easterly winds are generally fine on this coast but make the run back across the bay choppy.

Visibility is usually good (15–25 m) in oceanic water; currents can be strong further offshore. The long run south along an exposed coast means operators need reasonably good seas; winter westerlies are ideal.

Descend west over the wall, head south along the sand edge at about 25 m, then follow the reef as it turns east and ascend gradually over about 30 minutes to the 10–12 m shallows, where the seals play. Stay low on the bottom and let the seals approach; do the safety stop mid-water.

Dive Jervis Bay runs seal dives and snorkels (roughly April–November); Deep 6 Diving Jervis Bay and Woebegone Freedive (Huskisson) also visit the seal colony in winter.
