Half Moon Bay Cerberus Swim Classic

The HMAS Cerberus, a decommissioned naval vessel serving as a breakwall, sets the scene for the Half Moon Bay Cerberus Swim Classic, an open water swimming race held in the sheltered sea of Half Moon Bay in Victoria, Australia. Organized by the Half Moon Bay Surf Life Saving Club, the event stands as one of the longest-running open water swimming fixtures anywhere in the state. The swim holds a prime spot on the Victorian open water calendar as the eighth and penultimate leg of the Great Victorian Swim Series. Swimmers gather on the sand in February to contest courses designed for various levels of endurance, featuring headline distances of 1.2 kilometres and 2.5 kilometres alongside 200-metre and 300-metre junior dashes.

Race morning typically brings mild weather and flat, tranquil conditions across the crescent, making it an inviting arena for both veterans and newcomers. Swimmers consistently regard the event as a firm fan favorite, drawn back each season by a buzzing beachfront atmosphere and an exceptionally warm, friendly community welcome on the sand.

HMVS Cerberus: the ironclad breakwater in the shallows

The race takes its name from HMVS Cerberus, recognized today as the only surviving vessel of its kind on the globe. Built with a shallow draught and a remarkably flat hull, the ironclad was notorious in heavy seas for rolling up to forty degrees during bad weather. Today, its resting place could hardly be calmer: the wreck sits grounded in roughly ten feet of water, less than 650 feet from the shoreline of the swimming beach. The warship was deliberately scuttled in 1926 to serve as an artificial breakwater for the nearby Black Rock Yacht Club. Decades of marine exposure took their toll, culminating in a structural collapse in 1993 that led maritime authorities to establish a 100-metre exclusion zone around the hull. To stabilize the vessel and prevent further deterioration, the ship's four massive 18-ton guns were carefully lifted from the main deck in 2004 and positioned on the surrounding seabed. Swimmers today glide safely outside this perimeter.

Port Phillip Bay and twenty thousand years of Bunurong coastline

The body of water where swimmers compete has undergone dramatic transformations across human history. Bunurong oral traditions record the initial marine inundation of Port Phillip roughly 10,000 years ago, followed by a long arid period where the bay entrance became blocked and the basin evaporated, before oceanic waters flooded back approximately 1,000 years ago to create the modern coastline. Bunurong people have inhabited the eastern margins of this bay for more than 20,000 years. Tangible reminders of this deep Indigenous connection remain preserved immediately above the swimming beach. Ancient shell middens layered with charcoal from family cooking fires, stone implements, and animal remains lie nestled inside the coastal dunes and exposed atop the cliffs of neighboring Beaumaris. Stepping across the sand before the morning briefing, swimmers tread paths shaped by thousands of generations of traditional owners who harvested the exact same intertidal waters.

Red Bluff cliffs, marine shallows and the Sandringham submarine

Half Moon Bay is flanked by the striking Red Bluff Cliffs. This sheltering geography creates a calm, crescent-shaped natural amphitheatre where swell is kept to a minimum. The intertidal shallows stretching out to a depth of two metres are strictly protected, prohibiting any collection of crabs, shellfish, or marine snails and fostering an abundant aquatic habitat that makes the bay popular for snorkelling. HMVS Cerberus is not the only historic vessel anchoring the coastal engineering of this shoreline. About three kilometres up the coast at the Sandringham Yacht Club lies the submerged hull of HMS J7, a British First World War submarine launched at Devonport in 1917 and sailed to Australian waters two years later. Scuttled in 1930 to create a harbor breakwater, the submarine hull was eventually encircled by a stone marina, remaining visible in place today as another fascinating relic along this coastline of scuttled iron.

Half Moon Beach: Victoria's oldest lifesaving club and fish and chips

The host organization for the swim, the Half Moon Bay Surf Life Saving Club, holds a storied place on the Victorian coast as the state's very first surf lifesaving club, established in 1910. Once the race is done and the medals are handed out, the focal gathering point on the seafront is the Cerberus Beach House, situated at the southern tip of the cove. Known as a beloved local institution, it is where competitors rehydrate, recover, and order baskets of hot fish and chips to eat. Sitting by the edge of the bay with a view across to the shallows, there are few better places to celebrate a morning spent racing through the calm sea.
