Bonnyrigg is a suburb in Sydney’s south-west, about 36 kilometres from the CBD, in the City of Fairfield. Today it is known for its diverse cultural and religious communities, residential character, and ongoing urban renewal, with a local identity shaped by both long-established families and newer migrant communities.

Vietnamese, Chinese and Khmer (Cambodian) are the most common non-English ancestries in Bonnyrigg, according to the 2021 Census.

Early Scottish settlers in the region named Bonnyrigg after a town in Midlothian, Scotland. "Bonny‟ means pretty or pleasant while "rigg" refers to a ridge or land elevation. The name Bonnyrigg was officially lodged with the Geographical Names Board, Department of Lands as a suburb on 21 March 1975.

In 1803, Governor Philip King granted land in the Bonnyrigg area for an orphanage, and a two-storey Georgian building was erected on Brown Road as the Male Orphan School children’s residence. That building, later extended around 1914, remains one of the suburb’s most important heritage links to its nineteenth-century past.

During the 1870s purchasers of the Orphans land in Bonnyrigg and surrounding areas further subdivided their holdings to create smaller lots
suitable for family-run poultry farms, dairy farms and market gardens. With its favourable soil and climate, the area west of Fairfield developed as a prime agricultural district for the next century.

The post-World War II era construction boom saw rural land in the Fairfield district listed for residential and commercial development. The Housing Commission, established in 1941 to oversee the provision of public housing in New South Wales, was given powers to acquire land to tackle the critical housing shortage as thousands of people resettled after the war. In 1980 the Housing Commission acquired 294 acres of land at Bonnyrigg, bounded by Cabramatta, Edensor and Smithfield Roads, and embarked on an ambitious public housing project – the Bonnyrigg Estate. During the 1980s thousands of people established themselves at Bonnyrigg Estate – a place that represented the start of a new life for many families and provided the first experience of Australia for many new migrants.
