Statistical Area (SA2) Boundary Analysis

This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.

SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).

Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

DemographicsPopulation Growth in Ballajura

Table Chart PROFILE FAQ

Ballajura has an estimated 19,902 residents, up from 18,505 at the 2021 Census — a change of 1,397 people, or 7.5%. Growth has averaged 0.8% a year over five years. Overseas migration accounts for 69.2% of that increase. That puts 836 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.

Detail

According to research from AreaSearch, the resident count in Ballajura stands at roughly 19,902 as of Aug 2026. This reflects an addition of 1,397 people (7.5%) compared to the 18,505 people recorded during the 2021 Census. Such expansion is calculated using the June 2025 ABS estimated resident population figure of 19,879 alongside 24 validated new addresses documented following the Census date. Consequently, the locality exhibits a population density of 835 persons per square kilometer, aligning closely with typical benchmarks recorded across AreaSearch locations. Furthermore, the local 7.5% post-census rise falls within 2.0 percentage points of the 9.5% figure seen across Australia, indicating solid expansion dynamics.

Inbound international migration served as the core engine of this demographic increase, generating roughly 69.2% of total population additions over recent timeframes. Forecast modeling by AreaSearch incorporates 2024 ABS/Geoscience Australia projections for individual SA2 localities anchored to 2022 as a starting benchmark. For uncovered SA2 districts or projections extending beyond 2032 across all sectors, age-bracket growth trajectories from the 2023 ABS Greater Capital Region release (built on 2022 data) are applied. Anticipated demographic trajectories place the locality within the lower quartile of nationwide statistical areas, with projections indicating an expansion of 518 persons by 2041 relative to current annual ERP figures, translating to an overall growth rate of 2.5% across the 16 years.

Residential SupplyHousing Development & Building Approvals in Ballajura

Table Chart PROFILE FAQ

98 new dwellings have been approved in Ballajura over the past five years, an average of 19 a year. That is 1.0 approvals per 1,000 residents. Of the 20 dwellings approved in the latest reporting year, 95% were detached houses and the rest townhouses or apartments. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

Residential building approvals in Ballajura have averaged roughly 19 dwellings per annum, amounting to 98 homes across the preceding 5 financial years. With an influx averaging 7.7 new residents annually for each residence constructed between FY-22 and FY-26 across the past 5 financial years, residential supply falls considerably short of incoming demand, creating heightened competition among purchasers and upward pressure on pricing. Meanwhile, construction costs for new dwellings average $271,000—a level below regional norms that points to accessible entry pricing for home purchasers. Additionally, $2.1 million in commercial building permits was authorized during the current financial year, highlighting muted commercial building activity.

Construction levels in Ballajura remain notably subdued when benchmarked against Greater Perth, sitting 91.0% below regional average per person. Although local construction momentum has strengthened in recent periods, this limited flow of new dwellings generally bolsters demand and valuations across established real estate. This constrained pace similarly tracks below nationwide standards, reflecting an established suburban landscape alongside likely urban planning constraints. Recent approvals comprise 95.0% detached houses and 5.0% medium and high-density housing, preserving a low-density suburban layout centered around freestanding homes that appeal to buyers seeking space. An estimated ratio of 807 people per residential approval emphasizes the subdued, low-volume development environment. Projections indicate Ballajura will add 495 residents leading up to 2041, based on the latest quarterly calculations from AreaSearch. Under existing building trends, incoming residential construction appears positioned to comfortably satisfy local requirements, establishing favorable circumstances for purchasers and creating capacity for demographic expansion to surpass projected figures.

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 — 24 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (18,505 at the 2021 Census → 19,902 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 (504031056). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the Ballajura SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this Ballajura 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 Ballajura 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.
