Meet the site
Triangle Reef, also called South Triangle Reef, is the reef running out from Beaumaris Beach in front of the life saving club, named for the triangular navigation marker on its seaward end. It is the deepest of the Ricketts Point sanctuary sites, reaching 8 m at its outer edge, which gives it a little more variety than the platforms to the north-west: a shallow inner flat, a middle zone of gutters and low ledges at 3-5 m, and an outer edge with undercuts dropping onto sand. That extra depth, and the fact that the life saving club beach is a proper sandy beach with showers and toilets, makes it the most popular part of the sanctuary for actual scuba training as opposed to snorkelling, and on weekend mornings there are often several classes on the sand. The fish are those of the whole sanctuary: snapper and zebrafish in numbers, flathead, dusky morwong, old wives and moonlighters, octopus in the holes, stingrays and fiddler rays on the sand and Port Jackson sharks under the outer ledges in the cooler months. The outer edge, being deeper and less trampled, has the best invertebrate cover, with sponges, bryozoans, sea tulips, nudibranchs and cushion stars. It is a very good night dive; the marker makes an easy turning point and the club beach a lit, obvious exit. The reef is popular enough that Parks Victoria asks visitors to avoid trampling it, so enter and exit on the sand rather than across the rock, and keep fins up over the shallow flat. Table Rock and the Sea Scouts Jetty are a short swim or drive to the south-east for a second dive.
