Marengo Reefs Marine Sanctuary sits just off the Victorian coastline and offers beginner divers a genuine taste of temperate Australian reef life. The site is accessible from shore or by boat, with depths ranging from 1 to 15 metres, making it manageable for those still building confidence underwater. Visibility is variable, so conditions change from visit to visit. The reef and surrounding kelp forest shelter a good mix of creatures including nudibranchs, tubeworms, sea urchins, abalone, leatherjackets, and blue-throated wrasse. Port Jackson sharks and Australian fur seals also frequent the area. Moderate currents and surf can catch beginners off guard, so check conditions before entering.
