Brentwood (WA)

Population growth drivers in Brentwood are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

As of November 2025, the estimated population of Brentwood is around 2,307 people. This represents an increase of 154 individuals since the 2021 Census, which reported a population of 2,153. The latest estimate by AreaSearch, based on examination of the ABS's ERP data release from June 2024 and additional validated new addresses, is 2,276 residents. This results in a density ratio of approximately 2,592 persons per square kilometer, placing Brentwood in the upper quartile relative to other locations assessed by AreaSearch. Over the past decade, ending in 2021, Brentwood has shown resilient growth patterns with a compound annual growth rate of 1.1%, outpacing its surrounding SA3 area. The primary driver of population growth was overseas migration, contributing approximately 77% of overall population gains during recent periods.

However, all factors including interstate migration and natural growth were positive contributors. 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 and to estimate growth post-2032, AreaSearch utilises growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). Based on projected demographic shifts, an above median population growth is expected for Brentwood. According to aggregated SA2-level projections, the suburb is anticipated to grow by 307 persons to reach a total of 2,614 residents by 2041, reflecting a gain of approximately 16.6% over the 17-year period.

AreaSearch analysis of residential development drivers sees Brentwood recording a relatively average level of approval activity when compared to local markets analysed countrywide

AreaSearch analysis of ABS building approval numbers indicates approximately 2 new homes approved annually in Brentwood. Between FY-21 and FY-25, around 13 homes were approved, with none yet recorded for FY-26.

Over the past five financial years, an average of 16.9 new residents per year has been associated with each home built. This supply lag suggests heightened buyer competition and pricing pressures, with developers targeting the premium market segment as evidenced by average dwelling construction values of $1,023,000. Compared to Greater Perth, Brentwood's construction levels are 82.0% below the regional average per person, supporting stronger demand and values for established dwellings. Recent construction comprises 67.0% detached houses and 33.0% attached dwellings, with a growing mix of townhouses and apartments. The area has approximately 392 people per dwelling approval, reflecting its established nature.

By 2041, Brentwood is projected to grow by 384 residents. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and price growth.

Brentwood has seen below average employment performance when compared to national benchmarks

Brentwood has an educated workforce with professional services well-represented. Its unemployment rate was 4.6% in the past year, with estimated employment growth of 3.9%.

As of June 2025, 1,308 residents are employed while the unemployment rate is 0.7% higher than Greater Perth's rate of 3.9%, and workforce participation is similar at 65.2%. Key industries for Brentwood residents include health care & social assistance, professional & technical services, and education & training. The area specializes in professional & technical jobs with an employment share 1.4 times the regional level. However, construction has a limited presence with 7.1% employment compared to the regional average of 9.3%.

Employment opportunities locally may be limited as indicated by the Census working population count versus resident population. Between June 2024 and June 2025, employment increased by 3.9%, while labour force grew by 5.4%, leading to a 1.4 percentage point rise in unemployment. In contrast, Greater Perth saw employment growth of 3.7% and labour force growth of 3.8%, with a slight 0.1 percentage point increase in unemployment. Job and Skills Australia's national employment forecasts from September 2022 project national employment growth of 6.6% over five years and 13.7% over ten years, with varying rates across industries. Applying these projections to Brentwood's employment mix suggests local employment should grow by 6.8% over five years and 14.2% over ten years, though this is a simplified extrapolation for illustrative purposes only.
