For more than 30,000 years,
Aboriginal people from the
Cabrogal–
Gandangara tribe have lived in the area.
1850s–1920s European settlement began early in the 19th century and was supported by railway construction in 1856. One of Sydney's oldest trees, the
Bland Oak, was planted in the 1830s in Carramar. At the turn of the 20th century the area had a population of 2,500 people and with fertile soils, produced crops for distribution in Sydney. The council was first incorporated as the
Municipal District of Smithfield and Fairfield on 8 December 1888, becoming the
Municipality of Smithfield and Fairfield from 1906. In December 1901, a major bushfire emerged from what is now
Fairfield Heights through to the railway line at
Canley Vale, where it destroyed many houses in its path as its crossed creeks, and also annihilated acres of vines and orchards between
St Johns Park and Fairfield. On 26 October 1920, the council's name was changed to the
Municipality of Fairfield, in recognition of the changing centre of business in the council area.
1940s–1970s The Cabramatta Civic Hall, completed in 1944 to a design by J. A. Dobson, was the Cabramatta and Canley Vale seat from 1944 to 1948 and the Fairfield Council seat from 1949. Rapid population increase after World War II saw the settlement of many ex-service men and European migrants. Large scale Housing Commission development in the 1950s swelled the population to 38,000. From 1 January 1949, under the
Local Government (Areas) Act 1948, the 'Municipality of Cabramatta and Canley Vale' was amalgamated into the Municipality of Fairfield. In the , the population had reached 114,000 and was becoming one of the larger local government areas in New South Wales. On 18 May 1979, the Municipality of Fairfield was granted
city status, becoming the
City of Fairfield.
2000s–present On Friday 29 June 2001 the former deputy mayor of Fairfield and councillor from 1987 to 1998,
Phuong Ngo, was convicted of the 1994 murder of the local state MP for Cabramatta (and former deputy mayor),
John Newman, a crime which has been described as Australia's first political assassination. Ngo's alleged accomplices, Quang Dao and David Dinh, were acquitted and the identity of the killer who shot and fatally wounded Newman remains a mystery. Controversy has arisen in the years since then of the presence of Ngo's name on various council plaques from his time on council. In September 2006, Fairfield Council announced the introduction of a trial ban on
spitting in public on
public health grounds. However, it was reported that advice provided to council from NSW Health was that spitting does not impact on the transmission of infectious diseases. The law proved difficult to prosecute. In April 2024, the
first terrorist attack in Western Sydney's soil occurred at a
Wakeley church, where an
Islamic extremist stabbed bishop
Mar Mari Emmanuel and five others, though all survived the attack. In 2024, Following the decision by Woolworths, Big W and Aldi not to stock extra items for
Australia Day, Fairfield City Council resolved to provide free Australia Day
merchandise to residents. ==Business and industry==
