Sadleir, NSW 2168

Small, quiet family suburb of south-western Sydney about 37 km south-west of the Sydney CBD, in the local government area of the City of Liverpool. Sadleir was part of the Green Valley housing estate, subdivided from 1960, and is named after Richard Sadleir, the first mayor of Liverpool in 1872. At the 2021 census it had 3,243 residents with a median age of 33, laid out on a compact street network of just 22 streets. It remains a modest, working-class community - around a third of dwellings were public housing at the 2021 census and median household income was $946/week, well below the national median of $1,746 - and culturally diverse, with 54.0% of residents born in Australia and the largest overseas-born communities from Vietnam, Lebanon and Iraq.

At a Glance

Transport

Public transport is bus-based - Sadleir has no railway station and no rail line passes through the suburb; the nearest rail gateway is Liverpool station on the T2 Leppington and T3 Liverpool & Inner West Lines, a short bus ride away in bordering Liverpool. Residents catch bus services on the surrounding road network into Liverpool - the 853 and 854 routes run to Liverpool Station along the nearby Hoxton Park Road corridor, with full runs scheduled at about 31-33 minutes from the Carnes Hill end - and the T-way corridor buses connect the wider 2168 cluster to both Liverpool and Parramatta.

Schools

Sadleir Public School - NSW government primary school at 27 Insignia Street, Sadleir's in-suburb public school with about 380 students, including a Department of Education preschool and support classes for students with autism and intellectual disabilities (school website; EducationHQ; Better Education). Sadleir has no high school of its own: the nearest government secondary school is Miller High School in adjacent Miller, which takes secondary students from the 2168 cluster.

Shopping & Amenities

Sadleir is an essentially residential suburb with no significant shopping strip of its own - everyday retail and services are found in immediately adjacent suburbs: Miller Central, the Woolworths- and Aldi-anchored neighbourhood centre in neighbouring Miller (Miller Central directory), and the larger retail of Liverpool town centre, including Westfield Liverpool, in bordering Liverpool. Community facilities are limited to the school precinct on Insignia Street and the suburb's parks; for a small suburb there are no major civic or health facilities within Sadleir itself.

Parks & Outdoors

Landa Park is Sadleir's main public open space, holding the Edwin Wheeler Oval sportsground in the suburb's south. The suburb's quiet cul-de-sac streets, small neighbourhood reserves and school grounds suit family recreation, with the Cabramatta Creek corridor forming a green edge along the boundary with Cartwright to the south.

Property Market

The median house price in Sadleir was around ~$1.09M-$1.1M (Sep 2026): CoreLogic via YIP records a 12-month house median of $1,094,500 on 38 sales (30 days on market); view.com.au and property.com.au/PropTrack both put the median sold house price at $1,100,000 (21 sales and ~58 rental listings respectively) (mid-2026). See our full Sydney property price map for how the suburb compares across the city. A thin market of about 21-38 house sales a year and a negligible unit market, so no reliable unit median is published. Trackers agree well at the top end - YIP $1,094,500, view.com.au $1,100,000 and property.com.au $1,100,000 - with representative sales over the past year running from $922,000 (70 Gabo Crescent) through $1,080,000 (88 Sadleir Avenue) to $1,401,000 for a duplex site at 62-62A Sadleir Avenue ; one outlier tracker (Allhomes, $867,500) appears to reflect an older sales window. The suburb's housing stock is predominantly 1960s Green Valley estate homes on full blocks, and around a third of dwellings were still public housing at the 2021 census with low household incomes ($946/week median), so renewal has historically come through private renovation and the steady sale of former housing-commission stock; strong recent price growth and ~3.5% yields are drawing first-home buyers and investors.

New Developments

Sadleir has no significant new development - renewal is small-scale and incremental, with Liverpool City Council DA records for the suburb dominated by individual secondary dwellings, alterations and granny flats on its 1960s housing blocks, and no large greenfield or masterplanned projects in the suburb. The bigger-picture change is the slow private turnover of former housing-commission stock as the area matures and prices rise.

Jobs & Local Economy

Census data shows Sadleir's workforce is dominated by machinery operators and drivers, labourers and technicians, with most households earning in the lower-to-mid income bands ($946/week median household income in 2021). Local employment is minimal - Sadleir Public School is effectively the suburb's only workplace - so residents commute mainly to Liverpool for retail, hospital and council jobs, and to the industrial and logistics precincts along the Hoxton Park Road corridor toward Prestons and the M5/M7.
