Conical Harbour offers a wide depth range that suits intermediate divers looking to push into deeper territory, with the reef extending from 12 down to 40 metres. Visibility can be exceptional, matching the depth range on good days, though variable currents and surge mean conditions shift and you need to read the water before committing. Rock lobsters and abalone are the resident highlights here, tucked into crevices throughout the reef structure, alongside a variety of fish species. The cold Tasmanian water calls for a good wetsuit or drysuit, and strong currents can develop, so timing your dive around slack water is worth the effort.
