Pink Floyd is the newest named site in Botany Bay, identified by McFadyen and the St George Scuba Club in February 2025 about 400 m south-east of the long-established Henry Head anchorage, and named for the excellent wall and the abundance of pink invertebrates on it. The reef edge here is a sheer wall rising from the sand at about 26 m to a top at 17–20 m, with a trench running parallel to it, small gutters and scattered boulders, and overhangs of every size along the face. The colour is the point: sea tulips, gorgonians and sponges in several colours, sea fans hosting spindle cowries, basket stars, nudibranchs and yellow-kneed sea spiders.

It is also a serious macro site, with Sydney pygmy pipehorses, sawtooth pipefish (three together on one dive), long-snouted boarfish, pineapplefish under the ledges and blue devilfish in the overhangs; weedy seadragons were present historically but have declined since 2022. Over the reef large schools of silver sweep and yellowtail move about, and near the top of the wall at the starting point there are thousands of one-spot pullers. Port Jackson sharks, cuttlefish and octopus complete the list.

As with all the entrance sites, tide governs conditions – incoming or high is best, with 15–25 m visibility – and current can be strong enough that the site is often dived as a drift with a live boat. McFadyen says it needs quite a few dives to explore properly even on a scooter. It is a private-boat site with no charter service, ten to fifteen minutes from the Botany Bay ramps, and a natural first dive before Bare Island or Henry Head.

Boat only. From the Botany Bay ramps run to the northern side of the entrance east of Bare Island and past Henry Head; the wall is about 400 m south-east of the Henry Head anchorage, 10–15 minutes from Kyeemagh and 5 minutes from the Bare Island area. Anchor at the GPS mark in 18–26 m on the sand edge for a fixed dive, or drop divers up-current for a drift along the wall on the incoming tide.

No charter operator visits; identified by St George Scuba Club in February 2025.

Protected from the south by the Kurnell peninsula and diveable in southerly winds, but open to east and north-east swell into the bay entrance; seas under 1.5 m are best. Tide is the key variable: best on an incoming or high tide, when 15 m+ is normal and 25 m has been recorded; on the ebb after rain the surface layer is dirty, although McFadyen notes poor surface visibility here does not always mean poor bottom conditions. Strong tidal currents are possible along the wall, which is why it also works as a drift.

Shipping channel to the south – SMB and ascend on the line or under the boat.

Descend to the sand edge at 26 m, turn left and follow the wall south-south-east with the face on your right, checking the overhangs for pipefish and devilfish. Near the end of the dive move into the parallel trench and the small gutters at shallower depth, then finish along the 17–20 m reef top back towards the anchor. Alternatively drift the whole wall on the flood with an SMB.

No regular charter – private boat or dive-club (St George Scuba Club) only
