Port Bonython is the location of a deepwater port, gas fractionation plant and diesel storage facility west of Point Lowly in the Upper Spencer Gulf region of South Australia. It lies 16 km east-northeast of Whyalla, South Australia and approximately 370 km north-west of the State's capital city, Adelaide. The existing wharf is 2.4 kilometres long and is capable of berthing small Capesize ships with a maximum capacity of 110,000 tonnes. The wharf was established in 1982 and named after John Bonython, the founding chairman of Santos. The structure is leased to Santos by the Government of South Australia and is used for the export of hydrocarbon products. An oil spill at Port Bonython in 1992 resulted in loss of bird life and damage to mangrove habitats to the west and southwest of Port Pirie.
