Bidwill (NSW)

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

Bidwill's population is estimated at 4,310 as of Feb 2026. This reflects an increase of 108 people since the 2021 Census, which reported a population of 4,202. The change is inferred from AreaSearch's estimation of the resident population at 4,196 following examination of ABS data released in June 2024 and validation of 12 new addresses since the Census date. This equates to a density ratio of 2,854 persons per square kilometer, placing Bidwill in the upper quartile relative to national locations assessed by AreaSearch. The suburb's 2.6% growth since census is within 2.6 percentage points of its SA3 area (5.2%), demonstrating competitive growth fundamentals. Natural growth contributed approximately 55.00000000000001% 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, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group are applied to all areas for years 2032 to 2041. Future population trends anticipate lower quartile growth, with Bidwill expected to grow by 61 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 0.3% in total 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

AreaSearch analysis of ABS building approval numbers in Bidwill shows around 3 residential properties granted approval per year over the past five financial years, totalling an estimated 16 homes. In FY26 so far, 3 approvals have been recorded. This limited new supply likely keeps up with demand due to population decline, offering good choice to buyers. The average value of new homes is $206,000, under regional levels, indicating more accessible housing choices for buyers.

Additionally, $1.1 million in commercial approvals have been registered this financial year, suggesting a predominantly residential focus. Compared to Greater Sydney, Bidwill shows substantially reduced construction, 71.0% below the regional average per person, which generally supports stronger demand and values for established homes. This level is also below average nationally, reflecting the area's maturity and possible planning constraints. Recent development has been entirely comprised of standalone homes, 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 despite increasing density pressures.

At around 1693 people per approval, Bidwill shows a mature, established area. Population forecasts indicate Bidwill will gain 11 residents through to 2041, from the latest AreaSearch quarterly estimate. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Employment opportunities locally appear limited, as indicated by Census data on working population vs resident population. Over the 12 months to September 2025, employment increased by 8.4%, while labour force grew by 3.0%, resulting in a 3.9 percentage point decrease in unemployment. In contrast, Greater Sydney saw employment rise by 2.1% and unemployment increase by 0.2%. National employment forecasts from May-25 suggest national employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Bidwill's employment 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.
