Parwan is a rural locality 5 km south-east of Bacchus Marsh, near where the Parwan Creek joins the Werribee River. It is thought that the name is derived from an Aboriginal word meaning magpie.
The Parwan school was opened in 1868 and the Parwan railway station (on the line from Melbourne to Bacchus Marsh) was opened in 1886. Within a couple of decades there were numerous dairy farms. The Nerowie estate, occupying about two thirds of the parish of Parwan, was put up for closer settlement in the early 1900s and after World War I.
