St Johns Park was originally home to the Cabrogal people who inhabited the broad Liverpool-Fairfield area. When the First Fleet arrived in Australia, the colonial administration designated this area the parish of St John. Nineteenth century maps indicate a St Johns Farm in the area and it is through this connection that the suburb gained its name. By the 1890s there was a public school on Parkes Road, a post office, and a growing community, with an unusual number of Italians, who had arrived in the 1880s after the failure of the Marquis de Rays's expedition to New Ireland. The Bellotti and Gava families established vineyards on Bulls Road. Yugoslav migrants Theodore and Samuel Serovich arrived in 1885, also cultivating wine grapes. Both the Italian and Yugoslav communities were renewed and expanded during the period of postwar migration in the 1940s, and St Johns Park is still a very multicultural area. Members of the Gava and Serovich families still live in the area. Chicory and wild fennel growing along the banks of Clear Paddock Creek are relics of the early European farmers.

Landmarks
St Johns Park sits beside Clear Paddock Creek which runs along 500m. The 'Restoring the Waters' project, which was the first of its kind in Australia, consisted of the restoration of the concrete channel into a living stream. It took seven years to plan and build and was funded with the assistance of a $1.33 million grant from the NSW State Government through its Stormwater Trust.
