Dive-site story
On the northern headland at the entrance to Botany Bay, Henry Head slopes from sandstone boulders down to kelp and sponge gardens along the sand line. Exposed to open ocean swell, this active site supports temperate marine life across fallen rock blocks and low overhangs that shelter bottom-dwellers.
