St Marys, NSW 2760

Established Western Sydney centre 45 km west of the Sydney CBD and the historic heart of its district — the township grew up around the parish church of St Mary Magdalene (built 1837–40, one of NSW's oldest churches still holding regular services), the Bennett coach and wagon works, and later WWII-era industry, and was proclaimed the Municipality of St Marys in 1890. It is a working, multicultural suburb with a strong sense of community identity: the 2021 census population was 13,256. Housing is genuinely mixed — older post-war and mid-century homes on standard blocks alongside newer townhouses and multi-storey apartment buildings rising near the station — and agents describe a practical, family-oriented market popular with first-home buyers and commuters drawn by the train line and relative affordability (StMate). The suburb is now mid-revitalisation, with apartments built in anticipation of the new Sydney Metro line and a council-endorsed Town Centre Master Plan reshaping the Queen Street hub.

At a Glance

Transport

St Marys station is the suburb's biggest transport asset and a major local hub combining rail, bus and taxi services. Opened 1 May 1862 as 'South Creek' and renamed St Marys in 1885, the heritage-listed four-platform station is served by Sydney Trains T1 Western Line services and marks the end of the quadruple-track section of the Main Western line. A new St Marys station bus interchange opened on 7 March 2022 on the south side of Station Street, with Busways operating 12 bus routes via the station. The M4 Motorway runs along the suburb's southern boundary with entrance and exit ramps at Mamre Road, and the Great Western Highway passes through the town centre. St Marys is also the planned northern terminus of the Sydney Metro – Western Sydney Airport line, with a footbridge being built to link the station to the adjacent metro station.

Schools

St Marys Public School and South St Marys Public School are the suburb's two NSW government primary schools. St Marys Senior High School — a partially selective, government Years 11–12 (Stage 6) campus at 6–48 Kalang Avenue, St Marys — is the local senior secondary option (NSW Department of Education; Allhomes). Colyton High School, the Years 7–12 government high school serving the area, is based at 37–53 Carpenter Street on the St Marys side of the border with Colyton (Colyton High School website; StMate). Our Lady of the Rosary Primary School is the local Catholic K–6 school, Kurambee School is a NSW government school for specific purposes supporting students with disabilities, and St Mary's Flexible School offers an alternative senior-secondary pathway.

Shopping & Amenities

The main shopping centre is St Marys Village Shopping Centre on Charles Hackett Drive — a sub-regional centre anchored by Woolworths and Target with more than 40 specialty stores. The historic Queen Street precinct, St Marys' main street, holds the Penrith City Council St Marys business office at 207–209 Queen Street, and St Marys Corner — the former council chambers, now home of the St Marys & District Historical Society museum — sits opposite the station area. St Mary Magdalene Anglican Church (1837–40) anchors the heritage end of the centre, and cafes, bakeries, pubs and takeaway shops around the station and Queen Street give the town centre a straightforward neighbourhood feel.

Parks & Outdoors

St Marys sits between two creek systems — South Creek, which forms its western boundary, and Ropes Creek along its eastern edge. Cook Park is the suburb's main park and Penrith City Council has appointed a design-and-construction contractor to transform it. South Creek Park, on the northern side of the Great Western Highway near South Creek, displays the historic horse-drawn Bennett wagons built in St Marys in the 19th century. The heritage-listed St Marys Railway Station Group — station buildings, 1942 signal box and c.1880 goods shed — anchors the town-centre precinct.

Property Market

The median house price in St Marys was around ~$1.1–1.25M (mid-2026): OnTheHouse/Cotality AVM median house value $1,103,953 as at 31 July 2026; Allhomes median house sale price $1,250,000 (+44.3% over 12 months); YIP/CoreLogic house median ~$1.2M (127 house sales, 20% annual capital growth); StMate's listing-based median is lower at ~$865–930k (3-bed median $881k). See our full Sydney property price map for how the suburb compares across the city. House medians vary widely by method, a pattern typical of a fast-appreciating metro-linked market: sale-price trackers sit high, Cotality's AVM over the whole house stock reads ~$1.10M, and StMate's listing-based median is lower at ~$880–930k. Unit medians range ~$570k (StMate) to $640k (Allhomes) to ~$725k. Recent recorded sales include townhouses at $825–869k, apartments $440–660k and detached houses from $1.05M to $1.65M, with 4-bed houses clustered around $930k–1.25M (StMate; Allhomes). Current listings split roughly 45% houses, 29% apartments/units and 25% townhouses — one of the most mixed dwelling markets in the Penrith LGA — and the off-the-plan apartment pipeline near the station is expanding.

New Developments

St Marys is mid-way through its biggest transformation since the railway era. Penrith City Council endorsed the St Marys Town Centre Master Plan on 3 March 2025, refining the St Marys Structure Plan with detailed design for streets and precincts and positioning the centre for growth around the metro; implementation proceeds via amendments to local planning controls. The Sydney Metro – Western Sydney Airport line's northern terminus is under construction at St Marys — the 23 km, six-station line runs to Bradfield via Western Sydney International Airport and is scheduled to open in April 2027, delayed from an earlier 2026 target. New multi-storey apartment buildings have already been delivered near the station in anticipation of the metro, the station bus interchange was rebuilt in 2022 to make way for metro construction, and a new pedestrian footbridge will link the station to the metro concourse.

Jobs & Local Economy

St Marys' workforce skews to machinery operators and drivers — the suburb's most common occupation — reflecting its industrial and logistics base. Local employment centres on retail at St Marys Village Shopping Centre and the Queen Street town centre, plus manufacturing and warehousing along the Mamre Road and Ropes Creek industrial corridor; the rail network to Dunheved and Ropes Creek was built during WWII to serve local industry, and the station heritage listing records the area's long industrial role. Construction and transport roles are expanding with the metro build, and when the line opens St Marys becomes a direct rail gateway to Western Sydney International Airport and the Bradfield Aerotropolis employment precinct. Many residents commute by T1 train to Parramatta and the CBD.
