This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
South Windsor has shown very soft population growth performance across periods assessed by AreaSearch
Based on ABS population updates and AreaSearch validation, the estimated population of South Windsor as of May 2026 is around 6,128. This reflects an increase from the 2021 Census figure of 5,948 people, a growth of 180 individuals (3.0%). The change was inferred from AreaSearch's estimate of 6,123 residents following examination of ABS's latest ERP data release in June 2025 and an additional 32 validated new addresses since the Census date. This population level equates to a density ratio of 726 persons per square kilometer, comparable with averages seen across locations assessed by AreaSearch. South Windsor's growth rate since the census positions it competitively within 2.0 percentage points of the SA3 area (5.0%). Natural growth contributed approximately 68.0% of overall population gains during recent periods.
AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, NSW State Government's SA2 level projections are used, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Projections indicate a decline in overall population over this period, with the suburb's population expected to contract by 6 persons by 2041. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, projected to grow by 241 people.

Development
AreaSearch assessment of residential development drivers sees a low level of activity in South Windsor, placing the area among the bottom 25% of areas assessed nationally
South Windsor has seen approximately 13 new homes approved annually over the past five financial years ending June 2025. This totals an estimated 69 homes. As of May 2026, 9 approvals have been recorded for the current financial year. The average construction value of these dwellings is $425,000, slightly above the regional average.
There has also been $13.5 million in commercial approvals in this financial year. Relative to Greater Sydney, South Windsor shows around half the construction activity per person and ranks among the 28th percentile nationally for buyer options. This suggests limited new home choices while demand for established homes strengthens. The area's building activity comprises 82.0% standalone homes and 18.0% attached dwellings, preserving its low-density nature.
As of June 2025, there are an estimated 572 people per dwelling approval in the area. With population expected to remain stable or decline, South Windsor should see reduced housing pressure, potentially benefiting buyers.

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.
