Stirling North (known by locals as Port Augusta South) is a town located 8 kilometres (5 miles) east of Port Augusta in the Australian state of South Australia. Its origin was as a reliable watering point in low-rainfall country, used by Aboriginal people since time immemorial, and by settlers since the 1850s. Few people lived there until about 100 houses were built in the 1980s for railway employees and their families – Stirling North railway station has been an important railway junction for up to four main lines. Subsequent residential development was substantial; now the town serves essentially as a satellite to Port Augusta. From a population of 350 in 2008, Stirling North had a population of 2793 at the 2021 census.
