Hendersons Rock is an advanced Moreton Island boat dive built around extensive granite outcrops, kelp-covered ledges, deep gutters, caves, and overhangs on the island's eastern side. The site starts on a shallower pinnacle and then drops away into steeper terrain, so the dive can shift quickly from open rocky reef into darker ledges and more serious structure. Grey nurse sharks are one of the main reasons divers make the long run here, especially when they patrol the deeper gutters and cave areas around Hendersons Rock and nearby Cherubs Cave. Kelp beds, pipefish, nudibranchs, wobbegongs, Queensland groupers, and larger pelagic fish all add to the appeal, but this is still a site for experienced divers who are comfortable with depth, overhead features, and changeable current on the windward side of Moreton Island.
