Portsea Pier is one of Victoria’s most renowned shore dives. Located on the beach in Portsea’s Weroona Bay at the tip of the Mornington Peninsula, Portsea is one of the centres of Victorian diving. The pier is a superb dive for both the beginner and experienced diver, with new sights guaranteed almost every dive. The famous Weedy Seadragons are often found, as are seahorses, octopus, colonies of Cleaner Shrimps, rays, and a wide variety of temperate fish. Be aware of boat traffic and put up a surface marker buoy if you stray from under the pier.
