Smithfield lies approximately 31 kilometres west of the Sydney central business district and spans both the City of Fairfield and Cumberland Council jurisdictions, reflecting its role as a key western Sydney suburb.
The suburb reported a population of 13,160 in 2021, with a median age of 38. It features a multicultural demographic, where around 42 per cent were Australian-born, and significant communities originate from Iraq, Vietnam, Syria, Italy, and Lebanon.
Around 31 per cent of residents speak only English at home, while Arabic, Assyrian Neo-Aramaic, Vietnamese, Chaldean, and Spanish are also common home languages.
Transport infrastructure includes the Horsley Drive and Cumberland Highway, with Smithfield railway station not present. Instead, commuters rely on nearby Fairfield and Yennora stations, served by T2, T5, and T3 lines, complemented by several Transit Systems bus routes, such as the 806, which links to Parramatta and Liverpool. Commuting patterns show that approximately 52.7 per cent travel by car, 11.4 per cent use public transport, and 23.2 per cent work from home.
Smithfield features a mix of low‑density housing, industrial precincts and commercial strips. The substantial Smithfield–Wetherill Park Industrial Estate lies partially within the suburb and forms part of the Southern Hemisphere’s largest industrial zone.
Essential services are concentrated along Horsley Drive, including health clinics, multicultural eateries, specialty shops, and the Smithfield Tavern. At the same time, the Smithfield Square redevelopment will include a medical centre, gym, childcare, and a swim school. Retail needs are also met in neighbouring Fairfield, Cabramatta and Parramatta.
Recreational amenity centres on Brenan Park, a 20‑hectare reserve with sporting fields, playgrounds, picnic zones, courts and a shared walking‑cyclist track. Additional green spaces, such as Rosford Street Reserve, Smithfield Park, Beaumont Park, and Prospect View Park, provide urban forest, sports, and playground settings. Cycleways follow Prospect Creek, offering connections to Western Sydney Regional Park.
Education is provided by Smithfield Public School and Smithfield West Public School, with secondary students travelling to schools such as Fairfield High and Westfields Sports High.
Healthcare needs are met by local medical clinics, with major hospitals at Westmead and Fairfield accessible by car or public transport.
Smithfield maintains a diverse community fabric, underpinned by rail-bus connectivity, industry, green spaces, and established local services.
