The area was also used for market gardening, although there was a considerable amount of swampy or unimproved land when the Forest Hill Golf Club acquired an area for its Spring Valley golf course in 1948. The golf course is one of several in the sand belt country, extending from Huntingdale to Dingley Village. Residential settlement and industrial growth began during the late 1950s. Notable developments were the Volkswagen assembly plant adjoining the Westall railway station, and cable-making and bakery establishments. The Clayton South primary school had been opened in 1929 for the farming community, but the postwar residential growth required the opening of Westall primary and high schools in 1961 and 1963.
