Sydney's Westfield Investments Propriety Limited (now known as the Scentre Group or Unibail-Rodamco-Westfield) opened WESTFIELD SHOPPING CENTRE BLACKTOWN between August 1958 and July 1959. The complex, which was the very first Westfield-branded shopping hub, was located in the Greater Western Sydney suburb of Blacktown.

BLACKTOWN CENTRE, anchored by Sydney-based Winns, featured a supermarket and thirteen shops. Free parking was provided for ninety autos. Westfield sold the complex in 1973. In the 2020s, the WESTPOINT BLACKTOWN commercial centre spans 1,076,400 lettable square feet and contains 259 stores and services.

Anchored by Sydney-based McDowells, the open-air structure housed twenty-five shops. WESTFIELD PLAZA began trading to the public in July 1961. The current shopping precinct incorporates 1,074,500 lettable square feet and contains 259 shops and services.
