Watsonia was surveyed by Robert Hoddle in 1838 as part of the parish of Keelbundora, for subdivisional sale as farms. Until the 1870s, much of Watsonia remained part of the vast property holdings of John Brown. The Grace Park area was purchased in 1877 by Frederick Augustus Nell, and then by Frank Watson in the early twentieth century. Watson subdivided the property for housing in 1924. The area remained primarily rural until the 1940s, when property prices became affordable.
Watson and other landowners paid for the establishment of a railway station in order to attract property buyers. Watsonia railway station was named after Watson. Watsonia train station was opened on Monday 23 June 1924, between the existing Macleod and Greensborough Stations. The current Watsonia Station is in Zone 2 on the Hurstbridge railway line and is currently served by Metro Trains Melbourne. Watsonia Post Office opened around 1934.
In Watsonia 78.0% of people were born in Australia. The most common countries of birth were England 2.3%, China (excludes SARs and Taiwan) 2.0%, India 1.3%, Italy 1.0% and Sri Lanka 0.8%.
Watsonia has the Simpson Army Barracks, Yallambie which was originally known as the Watsonia Military Camp during World War II. This complex was built on the property formerly owned by Ainslie Meares. In 1951, surrounding land was purchased for the extension of the barracks.
