Mornington Pier offers one of Victoria's most accessible encounters with some of Australia's most unusual marine creatures. You'll enter from the beach and descend to depths between 2 and 10 metres, making this an ideal first pier dive. The visibility ranges from 6 to 15 metres, giving you clear views of the marine life living around the pier pylons. The real draw here is the diversity of cephalopods and cryptic creatures. Big-belly seahorses cling to the pylons, while weedy seadragons drift through the pylons in their characteristically languid manner. You'll often spot pale octopus tucked into crevices, and during certain seasons, giant cuttlefish and southern calamari squid appear in impressive numbers. The sandy patches between the pylons attract stingrays and Melbourne skates, while Port Jackson sharks rest on the bottom. Look for old wives darting between the structure and zebrafish adding splashes of colour. The mild current makes this site comfortable for new divers building their skills. Stay aware of boat traffic above, particularly on weekends, and watch for fishing lines around the pier structure. With facilities including parking, toilets, and a cafe nearby, you can easily spend several hours here making multiple dives.
