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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows South Wentworthville averaged around 48 new dwelling approvals each year over the past five financial years. This totals an estimated 242 homes. So far in FY-26, 15 approvals have been recorded. On average, 1.5 new residents per year per dwelling constructed were recorded between FY-21 and FY-25.

However, this increased to 7.9 people per dwelling over the past two financial years, reflecting the area's growing popularity and potential supply constraints. New homes are being built at an average expected construction cost of $450,000. The development consists of 24.0% detached dwellings and 76.0% townhouses or apartments. This shift from the area's existing housing (currently 57.0% houses) indicates decreasing availability of developable sites and reflects changing lifestyles and demand for more diverse, affordable housing options.

South Wentworthville has approximately 481 people per dwelling approval, reflecting an established area. According to AreaSearch's latest quarterly estimate, the location is expected to grow by 920 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.

As of September 2025, 3,555 residents were in work while the unemployment rate was 3.9% higher than Greater Sydney's rate of 4.2%.

Workforce participation was somewhat below standard at 66.6%, compared to Greater Sydney's 70.0%. A high 39.7% of residents worked from home, potentially influenced by Covid-19 lockdowns. Employment is concentrated in health care & social assistance, retail trade, and construction, with a particularly strong specialization in construction at 1.3 times the regional level. However, professional & technical services are under-represented, with only 8.0% of South Wentworthville's workforce compared to Greater Sydney's 11.5%.

The area appears to offer limited local employment opportunities. Over a 12-month period ending in May-25, employment increased by 1.3%, labour force by 2.9%, and unemployment rose by 1.4 percentage points. In contrast, Greater Sydney experienced employment growth of 2.1% and labour force growth of 2.4%, with a 0.2 percentage point rise in unemployment. National employment forecasts from Jobs and Skills Australia project national employment to expand by 6.6% over five years and 13.7% over ten years, with varying growth rates between industry sectors. Applying these projections to South Wentworthville's employment mix suggests local employment should increase by 6.6% over five years and 13.6% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
