Meet the site
Obelisk Beach is the southern of Middle Head's two little naturist beaches, a pocket of sand below the bushland of Sydney Harbour National Park looking across Obelisk Bay toward Chowder Bay and Georges Head, named for the navigation obelisks on the ridge above. Vizzbud describes it as 'a calm, easy dive best suited to beginners', mostly sandy with scattered rocky sections, stingarees on the sand, pipefish in the seagrass and small reef fish, and recommends it for training, refresher and navigation practice; it is frequently combined with Cobblers Beach on the northern side for a two-dive day. The VIZ club's Middle Head survey adds the important detail that the sand line east of the beach at 8–10 m leads along the north-east segment of the head to the sponge gardens, large boulders, crevices and swim-throughs that are the best of Middle Head. Close to the beach the dive is sand, seagrass and small rock with stingarees, pipefish, flathead, octopus and the odd seahorse; further east it becomes a proper reef with sponges and ascidians on the boulder faces, Port Jackson and crested horn sharks under them, blue groper, yellowtail schools, red morwong and, in the club's logs, sea turtles, lobsters and hammer octopus. The Beehive Casemate mine tunnel lies along the same face for those who know where to look. The cost is the steep path with gear and the naturist etiquette of the beach; the reward is a quiet, sheltered dive that scales from a beginner's sand paddle to a 450 m reef traverse. It suits new divers, navigation students and night divers, and the VIZ club's map is the guide to have. Details from Vizzbud should be confirmed on site; the VIZ survey is the more reliable source.
