Population
Willmot is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends
The suburb of Willmot had an estimated population of 2,580 as of May 2026, according to AreaSearch's analysis of ABS population updates and new addresses. This figure reflects a growth of 198 people since the 2021 Census, which recorded a population of 2,382. The increase is inferred from AreaSearch's estimated resident population of 2,571 in June 2025, along with three validated new addresses since the Census date. This results in a population density ratio of 2,835 persons per square kilometer, placing Willmot in the upper quartile nationally according to AreaSearch assessments. The suburb's growth rate of 8.3% since the 2021 Census exceeded both the SA3 area (3.6%) and the state average, positioning it as a growth leader in the region. Natural growth accounted for approximately 57.99999999999999% of Willmot's overall population gains during recent periods.
AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022, and NSW State Government's SA2-level projections for areas not covered by this data, released in 2022 with a base year of 2021. These projections indicate that Willmot is expected to experience population growth just below the Australian median statistical area average between 2032 and 2041, with an anticipated increase of 266 persons by 2041, reflecting a total increase of 10.0% over the 16-year period.

Development
The level of residential development activity in Willmot is very low in comparison to the average area assessed nationally by AreaSearch
Based on AreaSearch analysis using ABS building approval numbers derived from statistical area data, Willmot has seen approximately two new homes approved annually. Between the financial years 2021 (FY-21) and 2025 (FY-25), around thirteen homes were approved, with four more approved in FY-26 to date. Despite population decline in the area, housing supply has been adequate relative to demand, resulting in a balanced market with good buyer choice.
New properties are constructed at an average expected cost of $216,000, below the regional average, suggesting affordable housing options for buyers. This financial year, Willmot has registered $10,000 in commercial approvals, reflecting its residential nature. Compared to Greater Sydney, Willmot records significantly lower building activity, at 60.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established dwellings, although development activity has increased recently. Overall, construction levels in Willmot are under the national average, indicating an established area with potential planning limitations.
All new constructions have been detached dwellings, maintaining the area's traditional suburban character focused on family homes. With around 551 people per approval, Willmot indicates a mature market. According to AreaSearch's latest quarterly estimate, Willmot is projected to add 257 residents by 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.

Anchor projects include Bradfield City Centre (114 hectares with 10,000 future homes and 20,000 jobs), the Advanced Manufacturing Readiness Facility (AMRF), the toll-free M12 Motorway which opened on 14 March 2026, the Sydney Metro Western Sydney Airport line (now expected to open mid-to-late 2027 with a free interim bus service from 5 July 2026), and major upgrades to Mamre Road, Elizabeth Drive and Fifteenth Avenue. Sydney Water is delivering the Upper South Creek Advanced Water Recycling Centre and progressing the Aerotropolis Integrated Stormwater Schemes for the Wianamatta Badgerys, Cosgroves and Duncans Mulgoa catchments, with finalisation in early 2026 and Development Servicing Plan exhibition in Q2 2026. Bradfield Central Park construction is due to begin in the second half of 2026, with FDC Construction & Fitout appointed as head contractor in early 2026. The precinct is targeting more than 100,000 long-term jobs across advanced manufacturing, freight and logistics, aerospace and defence, agribusiness, healthcare, education and research.
Sydney Metro - Western Sydney Airport
A 23-kilometre driverless metro railway connecting St Marys to the new Western Sydney International (Nancy-Bird Walton) Airport and Bradfield City Centre via twin tunnels and elevated viaducts. The line includes six new stations: St Marys (interchange with the T1 Western Line), Orchard Hills, Luddenham, Airport Business Park, Airport Terminal, and Bradfield. As of early 2026 the project is in advanced construction, with platform installation complete at Bradfield Station and progressing at Airport Business Park and Orchard Hills. Track laying is underway between Luddenham and St Marys, with more than 6,400 tonnes of Australian-made rail steel to be installed across the alignment by mid-2026. The Stations, Systems, Trains, Operations and Maintenance package is being delivered by the Parklife Metro consortium, which will operate and maintain the line for 15 years. Twelve three-car Siemens Inspiro driverless trains will run on the line. Passenger services were originally targeted for late 2026 to coincide with the airport opening on 26 October 2026, however government and contractor advice now indicates the line will open in mid-to-late 2027 (with April 2027 the earliest date publicly reported). A free interim WSI Link bus service between St Marys and the airport is running until the metro opens. The project is supporting more than 14,000 jobs during construction.

Sydney Metro - Tallawong to St Marys Corridor (T2SM)
A protected passenger rail corridor of approximately 15km connecting the Tallawong Stabling Facility to St Marys Station, passing through Schofields Station and the Marsden Park growth area. The corridor preservation study is defining and protecting space for two potential rail services - a future extension of Sydney Metro North West terminating at Schofields, and a new metro-style service between Schofields and St Marys that would link with the Sydney Metro Western Sydney Airport line. The corridor was identified in the 2012 Long Term Transport Master Plan as one of Sydney's 19 major transport corridors requiring preservation. As of late 2025 the preferred corridor through Marsden Park has been protected, with land acquisition deferred until closer to construction. The link will provide interchange between Sydney's North West and South West growth areas and onward connections to the broader rail network.
Tallawong to St Marys (T2SM) Passenger Rail Corridor
The Tallawong to St Marys (T2SM) Corridor is a planned passenger rail link of approximately 15 kilometres connecting Sydney's North West and South West Growth Areas, with proposed stations at Schofields and serving the Marsden Park growth area. The corridor will define and protect land for two potential rail services: a future extension of Sydney Metro North West terminating at Schofields, and a new metro style service between Schofields and St Marys, providing an interchange with the Sydney Metro Western Sydney Airport line. Identified in the Long Term Transport Master Plan 2012 as one of Sydney's 19 major transport corridors requiring preservation, the preferred corridor from Tallawong through Marsden Park has been protected for future transport infrastructure. In March 2026 the proposed north-south rail link, which includes the T2SM corridor, was added to Infrastructure Australia's 2026 Infrastructure Priority List as a potential investment opportunity within the 2 to 4 year pipeline. Final business case work is being progressed, with land acquisition not required until closer to the time the infrastructure is delivered.
North West Treatment Hub
Sydney Water's North West Treatment Hub is a 10-year, approximately 2 billion dollar program upgrading three water resource recovery facilities (WRRFs) at Castle Hill, Rouse Hill and Riverstone to support rapid growth across Sydney's north west.

Employment
Employment conditions in Willmot face significant challenges, ranking among the bottom 10% of areas assessed nationally
Willmot's workforce comprises an equal mix of white and blue-collar jobs, with varied sector representation. As of December 2025, the unemployment rate stands at 18.5%, showing a growth of 5.8% compared to the previous year, according to AreaSearch data aggregation. In Willmot, 876 residents are employed while the unemployment rate is 14.3% higher than Greater Sydney's rate of 4.2%.
The workforce participation rate in Willmot lags behind Greater Sydney at 52.7%, indicating room for improvement. Census responses reveal that a moderate 16.1% of residents work from home, potentially influenced by Covid-19 lockdowns. Dominant employment sectors include transport, postal & warehousing, health care & social assistance, and retail trade. Willmot has a significant specialization in transport, postal & warehousing, with an employment share 2.9 times the regional level.
Conversely, professional & technical services employ only 3.0% of local workers, below Greater Sydney's 11.5%. The area appears to offer limited local employment opportunities, as indicated by the disparity between working population and resident population counts. Between December 2024 and December 2025, employment levels increased by 5.8%, while the labour force grew by 2.9%, causing a 2.3 percentage point drop in unemployment rate. In contrast, Greater Sydney saw employment rise by 2.2% and unemployment increase marginally despite a 2.3% labour force growth. Jobs and Skills Australia's national employment forecasts from May-25 project overall employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Willmot's employment mix suggests local employment should increase by 6.0% over five years and 12.6% over ten years, though these are simple extrapolations for illustrative purposes and do not account for localized population projections.
