The wetlands comprise Mandina Marshes, Mandina Lake, Cortina Lakes, Mrs Whites Lagoon, Caora and South Flagstaff, which form a chain between relict dune systems inland of the Coorong, about 250 km south-east of Adelaide. The water in the wetlands ranges from fresh to saline according to seasonal conditions. The area has a Mediterranean climate with cool, wet winters and warm, dry summers, and with an average annual rainfall of 450–500 mm. Most of the land is owned by Wetlands & Wildlife, a private conservation and land rehabilitation company, with the remainder expected to become the property of the company in due course.
