About this site
Portsea Pier Reef lies on the Port Phillip Bay side of the Mornington Peninsula, near the entrance to Port Phillip Heads southeast of Melbourne. The pier and its surrounding reef sit close to the town of Portsea, a popular boating and diving spot for locals along this stretch of the bay. The dive is shallow, with a maximum depth of around 6 metres, but it is rated advanced due to dynamic conditions and strong currents that have been reported around the pier pilings. Divers exploring the reef have also reported nudibranchs and stingrays among the structure.
