Williamstown is a small South Australian town on the southern fringe of the Barossa Valley wine-growing region. It is 51 km north east of Adelaide and 16 km south-east of Gawler. Williamstown was originally known as Victoria Creek.[5] The township was laid out in 1858 by Lewis Johnston, or Johnstone, on land he purchased in 1857, and named for his son.[3]
Williamstown has an elevation of 310 m and an average rainfall of 680 mm. It has a summer average temperature of 31 °C with temperatures often reaching the mid 40s, and a winter average temperature of 15 °C, with nights dropping below freezing, which makes the region excellent for the cultivation of fruits, especially grapes in the lower riverine alluvial deposits.
