Brentwood (WA)

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

The population of the suburb of Brentwood (WA) is estimated to be around 2,291 as of February 2026. This figure reflects an increase of 138 people since the 2021 Census, which reported a population of 2,153. The change is inferred from AreaSearch's estimate of the resident population at 2,238 in June 2024, along with one validated new address since the Census date. This results in a density ratio of 2,574 persons per square kilometer, placing Brentwood in the upper quartile relative to national locations assessed by AreaSearch. Over the past decade, from 2016 to 2026, Brentwood has demonstrated resilient growth patterns with a compound annual growth rate of 1.0%. This growth outpaced that of the SA3 area and was primarily driven by overseas migration contributing approximately 77.0% 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 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. Considering these projections, an above median population growth is projected for the suburb of Brentwood (WA), with an expected increase of 310 persons to reach a total of 2,601 by 2041. This reflects a gain of 17.3% in total over the 17-year period from 2026 to 2041.

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 shows Brentwood had approximately 2 new homes approved per year. Over the past five financial years, from FY-21 to FY-25, around 13 homes were approved, with none so far in FY-26. This results in an average of 16.9 new residents per year for every home built during this period.

Supply is lagging demand significantly, leading to heightened buyer competition and pricing pressures. Developers target the premium market segment, with new dwellings valued at an average of $1,023,000. This financial year has seen $256,000 in commercial approvals, indicating minimal commercial development activity. Compared to Greater Perth, Brentwood has significantly less development activity, 82.0% below the regional average per person. This limited new supply supports stronger demand and values for established properties. Nationally, this is also below average, reflecting the area's maturity and possible planning constraints. Recent construction comprises 50.0% detached houses and 50.0% attached dwellings, marking a significant departure from existing housing patterns (currently 69.0% houses).

The location has approximately 2352 people per dwelling approval, indicating an established market. Future projections show Brentwood adding 396 residents by 2041, potentially leading to heightened buyer competition and supporting price increases if current development rates continue.

Brentwood has an educated workforce with professional services well-represented. Its unemployment rate was 4.8% in the past year, showing a growth of 2.9%. As of September 2025, 1,313 residents were employed, with an unemployment rate of 4.8%, 0.8% higher than Greater Perth's 4.0%.

Workforce participation was 74.8%, close to Greater Perth's 71.6%. Only 9.6% worked from home, potentially impacted by Covid-19 lockdowns. Key industries include health care & social assistance, professional & technical services, and education & training. Brentwood specializes in professional & technical jobs, with a share 1.4 times the regional level, but has fewer construction jobs, at 7.1% compared to Greater Perth's 9.3%.

Employment opportunities seem limited locally, as indicated by Census data. Between September 2024 and September 2025, employment levels rose by 2.9%, labour force increased by 4.3%, leading to a 1.3 percentage point rise in unemployment. In contrast, Greater Perth had employment growth of 2.9% and marginal labour force increase. National employment forecasts from Jobs and Skills Australia, released May-25, project national employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Brentwood's industry mix suggests local employment could grow by 6.8% in five years and 14.2% in ten years, though this is a simplified extrapolation for illustrative purposes.
