Western Port Bay, often referred to simply as Western Port, is a vast tidal estuary and the second-largest bay in Victoria, Australia. Covering 680 square kilometers with an average depth of 6 meters and a maximum depth of 25 meters, it's a complex marine environment dominated by the large islands of French Island and Phillip Island. The bay opens to Bass Strait through two entrances, one on either side of Phillip Island, and is fed by several rivers including the Bunyip, Lang Lang, Bass, and Cardinia Creek. It is a Ramsar-listed wetland of international significance, featuring extensive seagrass beds, intertidal mudflats, mangroves, and deep channels that support a rich diversity of marine life. The bay is a premier destination for anglers seeking a variety of challenging saltwater species, from prized table fish to large sharks, all within an hour's drive of Melbourne.
