Long Flat is a semi-rural satellite locality of Murray Bridge in South Australia on the east bank of the Murray River south of the eponymous bridge and Swanport Bridge.[1]
The locality was formally named after the Long Flat Irrigation Area in March 2000.[1]
Its boundaries were formalised in March 2000 to cover a portion of land immediately across the river to the east of the main Murray Bridge conurbation.[1] It is bounded on the north and east by the Adelaide-Melbourne railway line, on the south by the South Eastern Freeway, and on the west by a 4.7km (02.9miles) stretch of the river. The defunct Rabila Railway Station is on the locality's northern boundary.[2] Long Island Recreation Park on Long Island, within the Murray River, is westerly adjacent to the locality.
