AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with a base year of 2022. For any SA2 areas not covered by this data, AreaSearch utilises the 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. Based on latest population numbers, South Wentworthville is expected to expand by 820 persons to 2041, reflecting an increase of 10.4% in total over the 17-year period.

AreaSearch analysis of residential development drivers sees South Wentworthville recording a relatively average level of approval activity when compared to local markets analysed countrywide

South Wentworthville averaged approximately 56 new dwelling approvals per year. The Australian Bureau of Statistics produces development approval data on a financial year basis, showing 284 homes over the past five financial years from FY-21 to FY-25, with six approved so far in FY-26. Over these five years, an average of 1.1 people moved to the area per dwelling built.

This suggests balanced supply and demand, stable market conditions, and new properties constructed at an average expected construction cost value of $457,000, aligning with regional patterns. Compared to Greater Sydney, South Wentworthville has similar development levels per person, supporting market stability, although building activity has slowed in recent years. New development consists of 26.0% standalone homes and 74.0% attached dwellings, promoting higher-density living for affordability and suitability for downsizers, investors, and first-home buyers. This represents a shift from the area's existing housing composition of 62.0% houses, indicating decreasing developable sites and changing lifestyles' need for diverse, affordable housing options. With around 252 people per dwelling approval, South Wentworthville exhibits low-density characteristics.

Population forecasts project an increase of 796 residents by 2041. At current development rates, new housing supply should comfortably meet demand, offering good conditions for buyers and potentially supporting population growth beyond current projections.
