As MONARO MALL was serving its first customers, another "Sydneyside" shopping centre was nearing completion. WARRINGAH ["wear-EENG-guh"] MALL started trading to the public April 4, 1963.

Developed by Sydney's Hammerson Group, WARRINGAH MALL encompassed 290,000 lettable square feet. It opened as Australia's second-largest shopping precinct (Greater Melbourne's CHADSTONE CENTRE being the largest). 

The original WARRINGAH MALL housed fifty shops and services. Located 7 miles north of the Sydney CDB, the open-air complex cost 6 million dollars to construct. Today, it has fully-enclosed and open-air components and envelops 1,356,000 lettable square feet and over three hundred shops and services. Australia's Westfield conglomerate established a 25 percent ownership share in March 2003. This was increased to 50 percent in October 2012...with the name of the centre being changed to WESTFIELD WARRINGAH.
