Heron Island - Pams is a bommie-and-staghorn-coral reef dive reached from a mooring line, with colourful reef fish on the descent and a healthy coral head as the main focus once you settle in. It is the kind of Heron dive where you balance easy visual structure with the chance of bigger moments, because batfish, whitetip reef sharks, nudibranchs, and passing manta activity all fit naturally into the same route.
