Cowrie Island is a gentle shore dive off New South Wales that rewards patient, slow-moving divers. The site combines reef and seagrass habitat across depths of 0 to 12 metres, making it manageable for beginners still building confidence. Visibility can vary considerably, so conditions on the day will shape your experience. The current is also variable, so check before you enter. The real draw here is the unusual marine life: weedy sea dragons and pygmy pipe-horses are among the more remarkable finds, alongside giant cuttlefish, gorgonians, and colourful sponges. Watch where you put your hands and feet, as sea urchins are present throughout.
