Port Phillip Bay is a world-class saltwater fishing destination spanning 2,000 square kilometers, making it the largest bay in Victoria. This vast, sheltered embayment is bordered by Melbourne and its suburbs, the Bellarine Peninsula, and the Mornington Peninsula. The bay's bottom is predominantly flat and sandy, with shallow areas averaging around 8 meters in depth and deeper sections reaching a maximum depth of 24 meters. Its formation as a drowned river valley creates a rich and diverse marine ecosystem, supporting a wide array of fish species and offering year-round fishing opportunities for anglers using boats, kayaks, and from shore.
