Scuba Diving at Nine Mile Reef
An offshore reef system off Tweed Heads with grey nurse sharks and pelagic activity.
Nine Mile Reef lies offshore from Tweed Heads and is one of the region's deeper and more exposed dive sites.
Grey nurse sharks aggregate here seasonally, and the reef's position attracts pelagic activity that inshore sites rarely produce.
Current and depth make it a site for experienced divers rather than a general reef trip.
Recommended: Advanced Open Water Diver. Parts of the site reach 30 m, which needs Advanced Open Water, ideally with the Deep specialty. What can I dive with my cert?
