Suburb (SAL) Boundary Analysis

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.

Growth has averaged 14.9% a year over five years, faster than 99% of areas nationally. 951 new addresses have been validated here since Census night. Interstate and internal migration accounts for 49.0% of that increase. That puts 910 residents on each square kilometre.

Detail

As of Aug 2026, the suburb of Treeby has an estimated population of approximately 7,494 residents, determined through AreaSearch's evaluation of broader ABS updates alongside 951 validated new addresses recorded since the Census. This figure indicates an expansion of 3,280 people (77.8%) from the 4,214 people recorded in the 2021 Census. The calculation is derived from an Estimated Resident Population of 7,345 established by AreaSearch using the ABS release from June 2025 together with the post-Census address additions. This equates to a population density of 909 persons per square kilometer, aligning closely with typical benchmarks across locations assessed by AreaSearch.

Surpassing both the state and the national average (9.5%), the 77.8% increase since the 2021 census positions the suburb of Treeby as a regional growth leader. Population expansion was predominantly fueled by interstate migration, which accounted for roughly 49.0% of recent population additions, though natural growth and overseas migration also served as positive contributors. For demographic forecasting, AreaSearch implements the ABS/Geoscience Australia projections released in 2024 (using 2022 as a baseline) for each SA2 area, while applying cohort-specific growth rates from the 2023 ABS Greater Capital Region projections (based on 2022 data) for locations post-2032 or missing from the primary series. Looking ahead, the suburb of Treeby is projected to experience extraordinary demographic expansion that ranks in the top 10 percent of statistical areas nationally.

Residential SupplyHousing Development & Building Approvals in Treeby

Table Chart PROFILE FAQ

1,281 new dwellings have been approved in Treeby over the past five years, an average of 256 a year. That places the area in the 99th percentile for residential development activity nationally, about 34 approvals per 1,000 residents a year. Of the 186 dwellings approved in the latest reporting year, 100% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 126, well below that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.

Detail

According to AreaSearch's review of ABS building approval data distributed across statistical boundaries, Treeby has maintained an approval pace of around 256 residential dwellings each year. Over the previous 5 financial years (between FY-21 and FY-25), an estimated 1,281 homes were approved, including 126 recorded to date in FY-25. An average of 4 residents per year arrived for every home constructed across the past 5 financial years (between FY-21 and FY-25), indicating that structural demand materially outpaces incoming residential supply, a dynamic that typically spurs heightened buyer interest and price appreciation.

Expected construction costs for these newly approved residences average $473,000. Additionally, commercial development approvals have reached $24.9 million during this financial year, underscoring ongoing non-residential investment. On a per-capita basis, residential approvals in Treeby surpass Greater Perth by 306.0%, presenting prospective buyers with extensive options even as construction momentum has moderated of late. This rate is substantially higher than figures seen nationally, illustrating robust builder confidence in the local market. All recent residential activity has consisted of standalone houses, reinforcing the low-density urban fabric and catering to buyers seeking separate homes. Furthermore, developers have focused more heavily on standard detached dwellings than the established housing stock (79.0% at Census) would suggest, reflecting sustained appetite for traditional family living despite density considerations. Generating approximately 49 people per dwelling approval, the locality displays the hallmarks of an expanding growth corridor. Demographic projections based on the latest AreaSearch quarterly estimate suggest Treeby will add 3,444 residents by 2041. Supported by current construction and planning trajectories, upcoming residential additions appear well positioned to satisfy demand, creating favorable market conditions for purchasers and potentially enabling population numbers to exceed established forecasts.

Jobs & IndustryEmployment Trends in Treeby

Table Chart PROFILE FAQ

4,991 residents of Treeby are employed, from a labour force of 5,042. Unemployment sits at 1.0%, with participation at 82.7%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.7% nationally over five years. That reflects industry composition only and makes no allowance for local population growth, so in an area growing as fast as this one it understates the likely rise in local jobs. The working-day population is estimated at 5,320, about 71% of the resident population, so more people leave the area for work than travel in. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.

Detail

Treeby features an exceptionally qualified local labor force with strong involvement in essential services, registering an unemployment rate of merely 1.0% and an estimated annual employment increase of 6.6%, according to AreaSearch's statistical analysis.

Participation in the workforce is remarkably elevated at 82.7%, well above the 69.9% recorded across Greater Perth. In Census filings, a modest 8.0% of local workers reported working from home, though this figure should be viewed in the context of Covid-19 restrictions.

The leading employment sectors for local workers are health care & social assistance, professional & technical, and construction. Treeby demonstrates notable workforce concentration in health care & social assistance, holding an industry share 1.2 times greater than the wider region. In comparison, accommodation & food accounts for a smaller footprint of 4.8% relative to the regional benchmark of 6.8%. Because the neighborhood is predominantly residential, internal employment opportunities remain constrained, as evidenced by Census counts comparing the working population against resident workers. Analysis of ABS and SALM data aggregated across broader statistical areas indicates that throughout the 12 months leading to March 2026, both employment and the labor pool expanded by 6.6%, maintaining a steady unemployment rate. Over the identical timeframe, Greater Perth saw employment rise by 2.0% and its labor force grow by 2.5%, yielding a 0.4 percentage point increase in unemployment. National workforce projections from Jobs and Skills Australia as of Mar-26 provide additional context regarding future occupational trends for Treeby.

How the numbers are built

Population

The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 951 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (4,214 at the 2021 Census → 7,494 now). Annual growth rates are compound (CAGR), not simple averages.

Age profile

Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to Aug 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".

Property sales

Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.

Rents

Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.

Development & infrastructure

Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.

Employment & income

Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.

Education, transport & amenities

School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.

Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.

Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (SAL51467). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

How do Treeby suburb boundaries differ from Statistical Areas?
This page uses Suburbs and Localities (SAL) boundaries (suburb-style geography). SAL represents commonly-known suburb names used in addresses, while Statistical Areas (SA2) are designed for census/statistical reporting. Even when sharing the same name, SAL and SA2 boundaries often cover different geographic areas with different populations.
Where does the data on this Treeby page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Treeby data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Aug 2026), property sales & rents (Aug 2026), infrastructure projects (Aug 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to Aug 2026), age profile (to Aug 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
