Dive-site story
What makes this site worth diving
At Botany Bay's northern entrance, Henry Head's rocky reef ledges drop to a sandy seabed at 18 to 22 meters. Large boulders form swim-throughs and overhangs sheltering Eastern blue devilfish and red indianfish inside dark crevices. Kelp beds along the sand line harbor weedy seadragons. Ocean swell and tidal inflow affect the site, making slack water ideal.

Plan this dive with care
- Brisk tidal currents cross the mouth of Botany Bay; time dives for slack water.
- Heavy boat traffic enters Botany Bay, requiring a surface marker buoy before ascending.
