Bidwill (NSW)

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

Bidwill's population is estimated at around 4,310 as of Feb 2026. This reflects an increase from 4,202 people recorded in the 2021 Census. The suburb experienced a growth of 108 people (2.6%) since the census. This change was inferred from AreaSearch's estimate of the resident population at 4,196 following examination of ABS' latest ERP data release in June 2024 and an additional 12 validated new addresses since the Census date. Bidwill's population density is approximately 2,854 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. The suburb's growth of 2.6% since census positions it within 2.6 percentage points of the SA3 area (5.2%).

Population growth was primarily driven by natural growth contributing approximately 55.00000000000001% of overall population gains during recent periods. AreaSearch is adopting 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 from these aggregations are applied to all areas for years 2032 to 2041. Future population trends anticipate lower quartile growth, with the suburb expected to grow by 54 persons to 2041 based on aggregated SA2-level projections, reflecting a decline of 1.4% 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 shows Bidwill has had approximately three residential properties approved per year over the past five financial years, totalling around 16 homes. In FY26 so far, there have been three approvals recorded. The area's population decline suggests new supply is meeting demand, offering buyers good choice while new homes are being built at an average expected construction cost of $206,000, below regional levels. This financial year has seen $1.1 million in commercial approvals, indicating a predominantly residential focus.

Compared to Greater Sydney, Bidwill's construction level is 71.0% below the regional average per person, suggesting stronger demand and values for established homes due to limited new supply. Nationally, Bidwill's construction level is also below average, reflecting its maturity and possible planning constraints. Recent development has been entirely standalone homes, maintaining Bidwill's suburban character with a focus on family homes appealing to those seeking space. New construction favours detached housing more than current patterns suggest (66.0% at Census), indicating robust demand for family homes despite increasing density pressures. With around 1696 people per approval, Bidwill is a mature, established area.

Population projections showing stability or decline suggest reduced housing demand pressures in the future, benefiting potential buyers.
