The Metropolitan Region Scheme, designed in 1955, had proposed that Whitford Beach, just beyond modern Hillarys's north, would be the limit of coastal settlement, and in 1962, a highway from Fremantle to Sorrento was suggested by the Government.[4] In 1967, a road to Whitford Beach was built after a major Catholic school, Sacred Heart College, relocated from inner-suburban Highgate into the region.

Wanneroo Shire Council and the R&I Bank began developing the Whitford precinct and planned a town centre, which ultimately became Westfield Whitford City, in the suburb's northeast, and Marmion Avenue was built. They asked for the Government to gazette a suburb here and this was done in 1971. Many streets in the new development (including the facing portion of what was to become Padbury were named for early explorers and pioneers of Australia. On 21 November 1978, Whitford City Shopping Centre was officially opened and our association started.
