Bidwill (NSW)

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

The population of the suburb of Bidwill (NSW) is estimated to be around 4,198 as of May 2026. This figure reflects a decrease from the previous census in 2021, which reported a population of 4,202 people. The latest estimate is based on AreaSearch's validation of new addresses and analysis of resident population data from June 2025 ABS ERP release, indicating a population of 4,179 plus an additional 12 validated new addresses since the Census date. This results in a population density ratio of approximately 2,780 persons per square kilometer, placing Bidwill in the upper quartile compared to other national locations assessed by AreaSearch. Natural growth contributed about 55% of overall population gains during recent periods.

For future projections until 2041, AreaSearch is using ABS/Geoscience Australia projections released in 2024 with a base year of 2022 for covered areas and NSW State Government's SA2 level projections released in 2022 with a base year of 2021 for uncovered areas. Growth rates by age group are applied to all areas from 2032 to 2041. By 2041, the suburb is expected to grow by approximately 51 persons, reflecting an increase of about 0.8% over the 16-year period.

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 shows Bidwill has averaged around 3 residential properties granted approval per year over the past 5 financial years ending FY26, totalling an estimated 16 homes. As of FY26, 4 approvals have been recorded. This area, experiencing population decline, has likely seen new supply keeping up with demand, offering good choice to buyers. New homes are being built at an average expected construction cost value of $206,000, under regional levels, indicating more accessible housing choices for buyers.

In FY26, $1.1 million in commercial approvals have been registered, suggesting a predominantly residential focus. Compared to Greater Sydney, Bidwill shows substantially reduced construction (71.0% below regional average per person), supporting stronger demand and values for established homes. This level is also below national average, 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.

At around 1675 people per approval, Bidwill shows a mature, established area. Population forecasts indicate Bidwill will gain 32 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.

As of December 2025, 1,071 residents are employed while the unemployment rate is 17.5% higher than Greater Sydney's rate of 4.2%.

Conversely, professional & technical jobs are under-represented at 2.5% compared to Greater Sydney's 11.5%. Limited local employment opportunities are indicated by the count of working population versus resident population.

In contrast, Greater Sydney saw employment rise by 2.2% with a marginal unemployment increase. Jobs and Skills Australia's national employment forecasts from May-25 project overall 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 extrapolation for illustrative purposes only.
