Nine Mile Reef, off Tweed Heads, has a reputation among locals as being a “sharky” spot. All year long, a good population of wobbegongs call the reef home, but are joined by leopard sharks in summer and grey nurse sharks in winter. But other shark species drop in from time to time, including bull sharks, bronze whalers and even the occasional hammerhead. The top of the reef sits at about 10 metres deep, dropping to 30 metres with the drop-off covered in numerous hard and soft corals. Reef fish are scattered across the shallower parts, with pelagic fish, sharks, turtles, stingrays, eagle rays and the occasional manta ray circling the reef.
