This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
Willmot is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends
Based on ABS population updates and AreaSearch validations, the suburb of Willmot's estimated population is 2,546 as of Feb 2026. This reflects a growth of 164 people since the 2021 Census, which reported a population of 2,382. The change was inferred from AreaSearch's estimate of 2,500 residents following the June 2024 ABS ERP data release and two additional validated new addresses since the Census date. This results in a population density ratio of 2,797 persons per square kilometer, placing Willmot in the upper quartile nationally according to AreaSearch assessments. The suburb's growth rate of 6.9% since the 2021 census exceeded its SA3 area's growth rate of 5.2%. Natural growth contributed approximately 58% of overall population gains during recent periods.
AreaSearch projections for Willmot are based on ABS/Geoscience Australia data released in 2024 with a 2022 base year, and NSW State Government SA2-level projections for areas not covered by this data. Future demographic trends suggest a population increase just below the median of statistical areas analysed by AreaSearch, with Willmot expected to grow by 294 persons to 2041 based on aggregated SA2-level projections, reflecting an overall gain of approximately 10% over the 17-year period.

Development
AreaSearch assessment of residential development drivers sees a low level of activity in Willmot, placing the area among the bottom 25% of areas assessed nationally
Willmot has seen approximately 2 new homes approved annually over the past 5 financial years ending FY-25. This totals an estimated 13 homes. In FY-26 so far, 3 approvals have been recorded. On average, 0.3 people per year have moved to the area for each dwelling built between FY-21 and FY-25.
New supply has kept pace with or exceeded demand, offering ample buyer choice and capacity for population growth beyond current forecasts. The average construction cost value of new homes was $216,000 in Willmot, below the regional average, suggesting more affordable housing options for buyers. This financial year, $10,000 in commercial approvals have been registered, reflecting the area's residential nature. Compared to Greater Sydney, Willmot has significantly less development activity, 59.0% below the regional average per person. Recent development has comprised entirely of detached dwellings, preserving the area's suburban nature and attracting space-seeking buyers.
With around 553 people per dwelling approval, Willmot reflects a highly mature market. Future projections show Willmot adding 248 residents by 2041. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
