As the MONARO SHOPPING MALL was welcoming its first patrons, another Sydneyside shopping centre was nearing completion. The first stores at WARRINGAH ["wear-EENG-guh"] MALL began trading to the public on April 4, 1963.

Developed by Sydney's Hammerson Group, the original 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). 

Located 9.9 miles north of the Sydney Central Business District, in the suburb of Brookvale, the open-air complex cost 6 million pounds to construct. There were 2,000 parking spaces and fifty-one charter shops and services. These included a Grace Brothers Homemakers' Store and Woolworths supermarket.

The original WARRINGAH was anchored David Jones, a Sydneyside department store. The building consisted of two main floors, with two mezzanine levels. There was 150,000 lettable square feet. Today, the mall has enclosed and open-air components and envelops 1,416,412 lettable square feet. There are 381 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.
