people from the Cabrogal tribe, a sub-group of the Gandangara tribe, have lived in the Fairfield area for over 30 000 years. White settlement came to the area in the early 19th century. An application for a post office at Fairfield Heights was made by Mrs Beard in 1950. In 1955, when the population had increased sufficiently a post office was opened.
Commercial area
Fairfield Heights mostly consists of low-density residential and commercial developments. Its commercial area is centred on The Boulevarde, the main street in Fairfield Heights, which is the highest point in the suburb at 40metres above sea level, offering striking views of the lower areas to the south and east. The Boulevarde mainly features cafes, ethnic restaurants, with a few featuring a hookah lounge, delis and convenient stores. Other businesses include dollar stores, health clinics, a radiology centre, cosmetic clinics, Domino's Pizza and Pizza Hut outlets, and a Vinnies store. Despite its small size, business hours in Fairfield Heights are slightly more extended than those in the neighbouring large suburb of Fairfield, with a few cafes, bars and restaurants remain open until 9pm.
Culture
Assyrian Sports and Cultural Club is the prominent club in the suburb, which features a casino, reception, restaurants and it has an entertainment quarter which hosts music concerts. The Club was originally opened in 1990, in The Boulevarde, where it held liquor and gaming licenses. In 1997 the Club bought the premises at 52-54 Stanbrook Street. The project of turning the gymnasium, squash courts and fruit shop into a club began in January 2000. The new club site was eventually opened by former Mayor Anwar Khoshaba in a ceremony that was visited by politicians, Councillors and many Assyrians. In 2003, the reception hall was built and the club grounds were expanded to fit weddings and other social events. Today, Hammurabi Restaurant is located on Cultural Club's old premises in The Boulevarde. It is an ethnic restaurant, serving Assyrian cuisine and Iraqi cuisine, and it features a reception hall for joyous events, namely for Assyrians.
