Location and features

St Georges Basin is a coastal waterbody located immediately adjacent to the Tasman Sea of the South Pacific Ocean, north of the town of Sussex Inlet and east of the town of St Georges Basin. The basin is fed by Wandandian Creek and Tomerong Creek and its primary outflow is to the Tasman Sea via the Sussex Inlet.[1] The basin covers a catchment area of 316 square kilometres (122 sq mi) and contains approximately 215,079 megalitres (7,595.4×10^6 cu ft) of water over an estimated surface area of 40.9 square kilometres (15.8 sq mi); and at an average depth of 5.3 metres (17 ft).[4]

Located with the basin are six artificial reefs that range up to 2 metres (6 ft 7 in) in depth.[3]

History

The traditional custodians of the land surrounding St Georges Basin were the Indigenous Australian Yuin people, who named the basin as Bherwherrae or Bherwherree.[1]

European surveyor Thomas Florance renamed the body of water as St Georges Basin on 29 November 1827, while tracing from Jervis Bay to Conjola.[1]
