Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, South Wentworthville's estimated population is around 7,233 as of Nov 2025. This reflects an increase of 320 people (4.6%) since the 2021 Census, which reported a population of 6,913 people. The change is inferred from the resident population of 7,187 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 38 validated new addresses since the Census date. This level of population equates to a density ratio of 3,996 persons per square kilometer, placing South Wentworthville (SA2) in the top 10% of national locations assessed by AreaSearch. Over the past decade, South Wentworthville demonstrated resilient growth patterns with a compound annual growth rate of 1.6%, outpacing the metropolitan area. Population growth was primarily driven by overseas migration contributing approximately 64.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections 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. Future population trends indicate an increase just below the median of statistical areas across the nation, with South Wentworthville (SA2) expected to increase by 870 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 12.3% over the 17 years.

Residential development activity is lower than average in South Wentworthville according to AreaSearch's national comparison of local real estate markets

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, South Wentworthville averaged approximately 48 new dwelling approvals annually over the past five financial years, totalling an estimated 242 homes. As of FY-26, 15 approvals have been recorded. Over these five years (FY-21 to FY-25), an average of 1.5 new residents per year per dwelling constructed was observed. However, recent data shows this has increased to 7.9 people per dwelling over the past two financial years, indicating growing popularity and potential supply constraints in the area.

New homes are being built at an average expected construction cost value of $450,000, with 24.0% detached dwellings and 76.0% townhouses or apartments, reflecting a shift towards higher-density living. This contrasts with the existing housing stock, which is currently 57.0% houses. The location has approximately 481 people per dwelling approval, indicating an established area. According to AreaSearch's latest quarterly estimate, South Wentworthville is expected to grow by 888 residents through to 2041.

At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
