Long Bay is the gentle shore dive of the Malabar coast, a protected inlet between the Long Bay Rifle Range headland and the Randwick Golf Club, dived from the ocean pool on its western side. It is another site that simply did not exist for divers until the Malabar sewage outfall was moved offshore in 1990; by the summer of 1991–92 it was not unusual to see 25 divers in the bay on a single morning, and it remains a popular easy dive and a very good night dive. From the entry the sand is only 2 m deep and shelves slowly to 6.5 m.

Fifty metres out two large rocks rise from the sand at 9–10 m with overhangs beneath them, and a narrow slit on the southern side leads through into a rocky area, more sand, a small drop-off and a distinctive anvil-shaped rock. Beyond is a kelp bed and a wide aisle between big boulders, with reef-and-sand edges everywhere. The life is what you expect of a sheltered sandy bay: bullseyes and eastern rock blackfish packed under the overhangs, flathead, stingarees and numbfish on the sand, common seadragons in the kelp, Port Jackson sharks in winter, bream, snapper, yellowtail and whiting, six-spined, reef, rough and velvet leatherjackets, and the occasional very large crayfish under a ledge.

Maximum depth is under 10 m, navigation is a simple out-and-back on a compass, and the entry and exit are protected, which makes it a good Open Water and night-diving site and a fallback when the ocean shore sites are blown out. The MV Malabar wreck lies on the opposite (northern) headland of the same bay but is a different and far more exposed dive.

At the intersection of Bay Parade and Howe Street, Malabar, the Randwick Golf Club has a three-tier car park; park on the lowest level nearest the water (public parking, busy on weekends). Walk 50 m down to the Malabar ocean pool below the clubhouse and out along the pool edge closest to the water. At high tide enter from the pool edge, at low tide from the rocks beside it.

Swim due east on the surface about 15 m to a small sand patch and descend in 2 m. Exit through the small channel beside the entry or 20 m further north.

Long Bay is deep and narrow and the pool sits on its sheltered western side, so the dive can be done in all but the biggest easterly and southerly seas; a 2–3 m swell from the east will still surge into the bay and over the pool. Northerly and westerly winds are irrelevant. Tide dictates the entry – pool edge at high, rocks at low – and the exit channel is easier on a higher tide.

Visibility is modest and drops after rain from the stormwater drain at the head of the bay. Nothing prevents it as a night dive, and it is better then.

From the 2 m sand patch head east to the two large rocks with overhangs at 9–10 m, take the narrow slit on the southern side of the hole and continue south-east over rock to sand, the small drop-off and the anvil-shaped rock, then work the kelp bed and the wide aisle between the large rocks. Return north-west on a compass bearing about 50 m to the entry.

Abyss Scuba Diving and Sydney Dive Academy use it for training and night dives; otherwise independent divers.
