Star Reef is a boat-access wall and drift dive off Queensland that drops into deep diving territory, running from 25 to 50 metres. That depth range puts the lower sections firmly beyond beginner limits, so newer divers should stay shallower and enjoy the upper wall where conditions are more manageable. Visibility ranges widely from 10 to 30 metres depending on conditions, and currents are generally mild, which helps when you are still getting comfortable with buoyancy near a wall. The reef is home to crinoids, the feathery, flower-like animals you will often spot anchored to rocky surfaces. This site dives year-round.
