Sparsely populated rural-residential suburb about 42 km west of the Sydney CBD, in the south-east corner of the City of Penrith and wedged between Cecil Park to the south and Horsley Park to the east. At the 2021 census it had just 1,235 residents. It is an undulating, hilly suburb of acreage and hobby-farm blocks with views all the way to the Blue Mountains, described by Penrith City Library as 'a secluded rural area... providing a close community atmosphere' — quiet, semi-rural and almost entirely residential acreage rather than village life.

Transport
No railway station, metro or light rail — Mount Vernon is entirely car-dependent, reached via Mamre Road (which forms part of its western boundary) and local roads such as Lincoln, Garfield and Truman Roads. Public transport is effectively limited to school bus services: route 9017 runs from Mount Vernon to Kemps Creek Public School and route 9624 links the Mount Vernon area with Prairiewood High School via Cecil Park (TransSee). The Westlink M7 motorway is accessible a short drive east through neighbouring Horsley Park and Cecil Park, and Mamre Road is a major freight corridor to the M4 at St Clair.
Schools
No school is located within Mount Vernon itself — there is no Mount Vernon Public School. The suburb's local government primary schools sit in immediately adjacent suburbs: Kemps Creek Public School (Kemps Creek, on the Mamre Road corridor to the west, which takes Mount Vernon students on school bus 9017) and Horsley Park Public School (government K–6 school of about 80 students on Walworth Road in Horsley Park to the east, whose catchment covers Mount Vernon addresses).
Shopping & Amenities
Mount Vernon has no shops, shopping centre or village commercial core of its own — the suburb is almost entirely rural-residential acreage with a handful of scattered roadside businesses. Everyday services are found in the immediately surrounding suburbs (Kemps Creek, Horsley Park and Cecil Park) and in the larger centres of Penrith and St Marys to the north (Microburbs).
Parks & Outdoors
The suburb itself is open, hilly acreage with long views to the Blue Mountains, laced with quiet rural roads named after US presidents (Garfield, Lincoln and Truman Roads) and with Kemps Creek running along its northern and western boundaries. Western Sydney Parklands — Sydney's largest urban park network, including sections around Horsley Park and Cecil Park — lies immediately east and south of the suburb, putting regional parkland and open space within easy reach of Mount Vernon's acreage properties.
Property Market
The median house price in Mount Vernon was around ~$3.6M–$4.1M (very thin, land-inclusive acreage market: Allhomes median house sale price $3,987,500; QuickProperty median house price $3.6M) (mid-2026). See our full Sydney property price map for how the suburb compares across the city. Very thin market: Mount Vernon has only about 362 properties in total, so annual sales number in the handfuls and medians are land-value driven and volatile. Allhomes records a median house sale price of $3,987,500 while QuickProperty's median is $3.6M (+21.2% year-on-year); OnTheHouse reports house median values up 274.4% over five years as at 30 June 2026 — an extreme figure that reflects low-volume acreage sales rather than a broad market. There is effectively no unit market (rural-residential zoning, no apartments). Treat any single median as indicative only.
New Developments
Development activity is minimal — the suburb is zoned for rural-residential acreage and planning applications are rare. The main infrastructure change is the NSW Government's Mamre Road upgrade program along the suburb's western edge, with a planned upgrade between Erskine Park Road and Kerrs Road (Mount Vernon) supporting freight growth toward the Western Sydney Airport corridor. No residential release areas or major subdivisions are underway in the suburb.
Jobs & Local Economy
Local employment is small-scale: agriculture, equine and horse-agistment properties, rural trades and services on the acreage blocks. The suburb sits beside major Western Sydney freight corridors — Mamre Road (being upgraded to support freight demand) and the M7/M4 motorways — so transport, logistics and warehousing jobs in neighbouring Kemps Creek, Horsley Park and the Erskine Park industrial area are the main nearby employment base, with longer commutes to Penrith and the Sydney CBD for most workers.
