Wistari Reef is located only one kilometre south of Heron Island and is a popular site for diving. The best dive site on this reef is the brilliant Wistari Wall. This sloping wall drops from 3 metres to 20 metres and is decorated with many lovely corals.
Cruising the wall divers will see pretty hard and soft corals and some wonderful gorgonian fans. Best done as a drift dive, the current that sweeps along Wistari Wall attracts pelagic fish like trevally, mackerel, rainbow runners, barracuda, batfish and tuna. A good population of reef fish also reside here, alongside turtles, tasselled wobbegongs and reef sharks.
Other resident species include coral trout, gropers and a family of Maori wrasse. This site is also a good place to see the occasional olive sea snake. These marine reptiles are high venomous, but also very docile and pose no threat to divers if left alone.
