As MONARO MALL was welcoming its first patrons, 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). 

In 1963, WARRINGAH MALL housed 50 shops and services. Located 7 miles north of the Sydney Central Business District, the open-air complex cost 6 million dollars to construct.

The original WARRINGAH was anchored David Jones, a "Sydneyside" department store. Today, it has enclosed and open-air components and envelops 1,356,000 lettable square feet. There are over 300 shops and services. Australia's Westfield Group established a 50-percent share in the complex in 2012, with its name being changed to WESTFIELD WARRINGAH.
