Oyster Harbour, also known by its traditional Noongar name Miaritch, is a permanently open estuary situated north of King George Sound near Albany in Western Australia. Covering approximately 15.6 square kilometres, this productive harbour is fed by the King River and Kalgan Rivers, which discharge into King George Sound. The harbour supports a working fishing fleet engaged in commercial fishing as well as oyster and mussel farming, with a dredged channel running around Emu Point to the Emu Point Boat Pens. Much of the deeper harbour floor — below 4 metres — is characterised by silty, nutrient-rich bare substrate, while the shallower banks support recovering seagrass meadows that provide important habitat for a range of fish species.
