Henry Head is a boat dive combining reef, wall and drift diving along a site that rewards divers who read the conditions well. Depths run from 12 to 26 metres in the deeper sections, with visibility ranging widely from 3 to 25 metres depending on the day. Moderate currents can strengthen without much warning, so staying aware of your position matters here. The walls and reef structure are draped in sponges and sea squirts, and this is a reliable spot to find weedy sea dragons, red Indian fish and the striking eastern blue groper. Cuttlefish, old wife, morwong and schools of yellowtail round out a solid temperate reef encounter.

The site dives best between July and October when visibility tends to improve and the cooler water brings out the more unusual species like eastern blue devilfish. Keep an eye on current direction before descending, as conditions can shift and boat traffic in the area means surfacing well away from your entry point needs a plan.
The site is accessed via boat, with dive charters operating from the Sydney area. A likely departure point is the boat ramp at Sans Souci.
The site is near a main shipping channel, so divers should be aware of boat traffic. Currents can be strong, and the dive should be timed with the tides.
