Brentwood (WA)

Population growth drivers in Brentwood are slightly above average based on AreaSearch's ranking of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Brentwood's population is estimated at around 2,251 as of May 2026. This reflects an increase of 98 people (4.6%) since the 2021 Census, which reported a population of 2,153 people. The change is inferred from the resident population of 2,248 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional one validated new address since the Census date. This level of population equates to a density ratio of 2,529 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Population growth for the area was primarily driven by overseas migration that contributed approximately 77.0% of overall population gains during recent periods, although all drivers including interstate migration and natural growth were positive factors.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and to estimate growth across all areas in the years post-2032, AreaSearch is utilising the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections released in 2023 based on 2022 data. Considering the projected demographic shifts, an above median population growth of national statistical areas is projected for the suburb of Brentwood (WA), with the area expected to increase by 283 persons to reach a total population of 2,534 by 2041 based on aggregated SA2-level projections, reflecting an increase of 12.4% in total over the 16 years.

Residential development activity is lower than average in Brentwood according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis of ABS building approval numbers indicates that Brentwood has received around 2 dwellings' development approval per year over the past 5 financial years, totalling an estimated 13 homes. No approvals have been recorded so far in FY-26. This results in an average of approximately 4.7 new residents per year for every home built between FY-21 and FY-25, indicating that demand significantly outpaces supply. The average construction value of new dwellings is $1,023,000, suggesting a focus on the premium market with high-end developments.

There have been $256,000 in commercial approvals this financial year, reflecting minimal commercial development activity compared to Greater Perth (81.0% below regional average per person). Recent construction comprises 50.0% detached houses and 50.0% attached dwellings, representing a shift from the area's existing housing composition of 69.0% houses. Brentwood has around 2231 people per approval, indicating a mature, established area with projected growth of 280 residents by 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and underpinning price growth.

Future projections show Brentwood adding 280 residents by 2041 (from the latest AreaSearch quarterly estimate). Should current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.
