Corio Bay is a substantial, shallow coastal embayment situated approximately 20 kilometers north of Yeppoon in Queensland's Livingstone Shire. As a declared Fish Habitat Area covering 4,652 hectares, it forms a critical part of the larger Shoalwater and Corio Bay Area Ramsar Wetland, adjacent to the Great Barrier Reef World Heritage Area. The bay is characterized by extensive sandy shallows, intertidal flats with seagrass beds, mangrove shrublands, rocky outcrops, and salt marshes, creating a highly productive estuarine environment. It connects inland via various creeks, such as Fishing Creek and Water Park Creek, and opens out to Keppel Bay, supporting a locally important recreational fishery renowned for crabbing and a diverse range of iconic sportfish.
