Large planned family suburb of Sydney, 44 km west of the CBD in the Penrith City Council LGA and part of the Greater Western Sydney region, within view of the Blue Mountains. It grew from a housing development launched in 1970 by the Latex Finance Company (which went bankrupt in 1976); the Land Commission of NSW acquired the land and extended it, and in late 1981 the Geographical Names Board split the area into the suburbs of St Clair and Erskine Park — the St Clair Post Office opened 17 March 1981. Today it is a well-established, family-oriented suburb with considerable parklands and modern facilities, bordered by Erskine Park Road to the east, the M4 Motorway to the north and Mamre Road to the west.

Transport
St Clair has no railway station and public transport is bus-based: Busways runs local services linking St Clair with St Marys station and surrounding suburbs — including the S11 St Marys–St Clair loop service and a service from Holy Spirit Parish School on Moore Street to St Marys Station running about every 15 minutes. St Marys station on the T1 Western Line is the interchange used by local commuters.
Schools
St Clair High School — the suburb's only public high school, on Endeavour Avenue; it was badly damaged by fire in June 2014 and reopened in October 2018 after a $20 million Department of Education rebuild adding 16 classrooms and a lecture hall. Some St Clair students are zoned to Erskine Park High School in neighbouring Erskine Park. Primary schools in the suburb include St Clair Public School, Banks Public School, Blackwell Public School, Clairgate Public School and Holy Spirit Catholic School.
Shopping & Amenities
St Clair Shopping Centre is the suburb's main retail hub; it underwent a major refurbishment in 2008 with new speciality stores, a food court and outdoor seating, and contains medical facilities (X-ray, pathology and optometrist), food outlets, newsagency, fashion and jewellery stores, electronics, the local library and a petrol station. The Blue Cattle Dog Hotel on the corner of Mamre Road and Banks Drive is the only pub in St Clair or Erskine Park, and St Clair Leisure Centre — a Penrith City Council-managed indoor recreation centre — sits behind the shopping centre. Community Junction Inc. manages community halls and programs covering St Clair, Erskine Park, Colyton, St Marys and Werrington.
Parks & Outdoors
St Clair is renowned for a family-oriented atmosphere and 'considerable parklands' that provide open space for recreational activities. Soccer fields with a recently constructed skate bowl sit beside the St Clair Shopping Centre and its two bordering schools, St Clair Leisure Centre behind the shops anchors the suburb's indoor sports and recreation offer (Ausleisure), and the suburb's green edges — bounded by Erskine Park Road, the M4 and Mamre Road — keep playing fields and reserves woven through the estate.
Property Market
The median house price in St Clair was around ~$1.15M–$1.2M (median house price: $1,150,000 per realestate.com.au suburb data; $1,200,000 per YIP/CoreLogic data) (mid-2026). See our full Sydney property price map for how the suburb compares across the city. House medians cluster tightly around $1.1–1.2M across trackers — consistent with St Clair's large 1970s–80s estate housing stock with newer infill. Houses sell fast. Unit median ~$984,500. Note: median quoted for 'St Clair' on some aggregators refers to the St Clair SA2, which also includes Erskine Park.
New Developments
The Land Commission of NSW's extension of the original 1970s estate created the suburb itself in 1981. In 2008 St Clair Shopping Centre underwent a major refurbishment adding speciality stores, a food court and outdoor seating. Penrith City Council completed a $2.146 million transformation of St Clair Leisure Centre — new activity and dance rooms, a refurbished foyer, modern kiosk, improved sports hall and greater accessibility (Ausleisure). St Clair High School was rebuilt at a cost of $20 million after the 2014 fire, reopening October 2018.
Jobs & Local Economy
Retail and local services anchor the suburb's employment, centred on St Clair Shopping Centre and its medical, food and service tenants. Penrith City Council is a major public-sector employer in the LGA, and the council-managed St Clair Leisure Centre provides local jobs. Many residents commute to the Penrith–St Marys employment corridor and to industrial areas in neighbouring Erskine Park and Minchinbury, which the suburb's location beside the M4 supports.
