The Harbour is used to shelter a fishing fleet carrying out commercial fishing and the farming of oysters and mussels. A significant number of waterbirds use the Harbour for feeding. The place is currently a family tourist center. Oyster Harbour is fed by the King and Kalgan Rivers and discharges into King George Sound.
