Bidwill (NSW)

Bidwill has shown very soft population growth performance across periods assessed by AreaSearch

As of November 2025, the estimated population of the suburb of Bidwill (NSW) is around 4,132 people. This reflects a decrease since the 2021 Census, which reported a population of 4,202 people. The current estimate is based on AreaSearch's validation of new addresses and analysis of ABS ERP data released in June 2024, indicating a resident population of 4,127. This results in a population density ratio of approximately 2,736 persons per square kilometer, placing Bidwill in the upper quartile relative to national locations assessed by AreaSearch. Natural growth contributed about 55% of overall population gains during recent periods.

For future projections until 2041, AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. Bidwill's population is expected to grow by 77 persons by 2041, reflecting an increase of approximately 4.7% over the 17 years.

The level of residential development activity in Bidwill is very low in comparison to the average area assessed nationally by AreaSearch

Bidwill has seen approximately 3 residential properties granted approval per year over the past five financial years ending June 2021. This totals an estimated 15 homes. As of FY-26, 2 approvals have been recorded. The average construction cost value for new homes is $206,000, which is under regional levels, indicating more affordable housing options in Bidwill.

In the current financial year, $990,000 in commercial approvals have been registered, suggesting a predominantly residential focus. Compared to Greater Sydney, Bidwill shows substantially reduced construction activity, with 72.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established homes. However, recent building activity has intensified recently, consisting entirely of detached houses, sustaining Bidwill's suburban identity with a concentration of family homes suited to buyers seeking space. New construction favours detached housing more than current patterns suggest (66.0% at Census), demonstrating ongoing robust demand for family homes in the area.

At around 1058 people per approval, Bidwill shows a mature, established area with a population growth projection of adding 194 residents by 2041, as estimated by AreaSearch's latest quarterly report. Should current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth in the future.

Employment opportunities locally appear limited as indicated by Census data.

In contrast, Greater Sydney saw employment grow by 2.6%, labour force expand by 2.9%, and unemployment rise by 0.3 percentage points. National employment forecasts from Sep-22 project growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Bidwill's industry mix suggests local employment should increase by 6.0% over five years and 12.6% over ten years, though this is a simplified extrapolation for illustrative purposes only.
