Bidwill (NSW)

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

Based on ABS population updates and AreaSearch validation, as of November 2025, Bidwill's estimated population is around 4310. This reflects a growth of 108 people since the 2021 Census, which reported a population of 4202. The change is inferred from AreaSearch's estimate of resident population at 4196 in June 2024 and 12 new addresses validated since the Census date. This results in a density ratio of 2854 persons per square kilometer, placing Bidwill in the upper quartile nationally. Bidwill's growth rate of 2.6% since census is competitive with its SA3 area's 5.2%. Natural growth contributed approximately 55% of overall population gains recently.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, NSW State Government's SA2-level projections from 2022 with a base year of 2021 are used. Growth rates by age group are applied to all areas for years 2032 to 2041. Future population trends anticipate lower quartile growth nationally, with Bidwill expected to grow by 75 persons to 2041, reflecting a total increase of 0.3% over the 17-year period.

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

Based on AreaSearch analysis using ABS building approval numbers from statistical area data, Bidwill has recorded approximately 3 residential properties granted approval per year over the past five financial years ending June 2021. This totals an estimated 16 homes. As of this date in FY-26, 3 approvals have been recorded. The area's population decline suggests that new supply is likely keeping up with demand, offering buyers good choice while new homes are being built at an average expected construction cost value of $206,000, under regional levels.

Additionally, $1.1 million in commercial approvals have been registered this financial year, indicating a predominantly residential focus. Compared to Greater Sydney, Bidwill shows substantially reduced construction activity, with 71.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established homes. Nationally, Bidwill's level is also below average, reflecting the area's maturity and possible planning constraints. Recent development has been entirely comprised of standalone homes, sustaining the area'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 14 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.

The labour market performance in Bidwill lags significantly behind most other regions nationally

Bidwill's workforce is balanced across white and blue-collar jobs with diverse sector representation. Its unemployment rate was 21.5% in the past year, showing an estimated employment growth of 8.7%.

As of September 2025, 1,129 residents are employed while the unemployment rate is 17.3% higher than Greater Sydney's rate of 4.2%. Workforce participation in Bidwill lags at 34.4%, compared to Greater Sydney's 60.0%. Dominant employment sectors include retail trade, health care & social assistance, and transport, postal & warehousing. Retail trade is notably concentrated, with employment levels at 1.8 times the regional average.

However, professional & technical services are under-represented, at 2.5% compared to Greater Sydney's 11.5%. Limited local employment opportunities are indicated by the Census working population vs resident population count. Between September 2024 and September 2025, employment increased by 8.7%, labour force by 3.2%, leading to a 4.0 percentage point unemployment reduction. In contrast, Greater Sydney saw employment rise by 2.1%, labour force grow by 2.4%, and unemployment increase by 0.2 percentage points. State-level data from NSW as of 25-Nov shows employment contracted by 0.03% (losing 2,260 jobs), with the state unemployment rate at 3.9%. Nationally, the unemployment rate is 4.3%. Jobs and Skills Australia's national employment forecasts from May-25 project overall 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 simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
