The Tuggerah Lakes estuary is a vast and productive coastal lagoon system on the Central Coast of New South Wales, comprising three interconnected bodies of water: Lake Munmorah, Budgewoi Lake, and Tuggerah Lake. This system covers approximately 80 square kilometers and is classified as an intermittently open, intermediate wave-dominated barrier estuary. It is mostly separated from the Tasman Sea, with a small channel at The Entrance allowing for tidal exchange, which creates a brackish water environment where freshwater from the catchment mixes with seawater. The catchment area is massive, stretching 700 square kilometers from the Watagan Mountains to the coast, feeding the lakes via numerous creeks and rivers. The system is renowned for its biodiversity and offers a wide variety of angling opportunities across its shallow lagoons, channels, and connected tributaries.
