Torrens Island, located in South Australia (postcode 5015), is a small, mostly industrial suburb situated just north of Adelaide's Port River. Known primarily for its significant infrastructure, the island is home to the Torrens Island Power Station, which supplies electricity to the region, and a sewage treatment plant serving metropolitan Adelaide. The island also features a quarantine station with historical significance, once used for disease control in the early 20th century. While largely uninhabited and not a residential area, Torrens Island plays a critical role in supporting Adelaide's energy and sanitation needs. Its proximity to the Port River and the Barker Inlet wetlands also makes it an area of environmental interest.
