One of the most exciting fish species commonly found on Noarlunga Reef are silver drummer,
Kyphosus sydneyanus. They are big, fast, often swim in large schools and are lots of fun to be in the water with.
During low tide when the inner reef is protected you might find a handful of them swimming among the sweep. During high tide when the waves are surging across the reef the silver drummer go crazy for morsels torn from the rocks.
This guy hanging with the sweep was a bit skittish and really did not want its image captured. After hovering mid-water for a while I finally got in a couple shots.
