Halbury is a former railway town in South Australia, west of the Clare Valley, halfway between Balaklava and Auburn. The railway ran from Balaklava to Blyth and further on into the Mid North of the state. Due to various reasons, this particular line became obsolete and the tracks were dismantled in the late 1980s. After Halbury, the railway line veered to the north-east, travelling on to the town of Hoyleton and then further north to Blyth.
