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.

Detail

According to research conducted by AreaSearch, Dianella - South has an estimated community size of approximately 15,088 as of Aug 2026. This represents an addition of 2,103 people (16.2%) compared to the 2021 Census tally of 12,985 people. This figure is derived from the ABS estimated resident population figure of 15,055 recorded as of June 2025 alongside 185 validated new addresses identified post-Census. Consequently, the local density stands at 2,999 persons per square kilometer, positioning the suburb in the top fourth of nationwide territories evaluated by AreaSearch. Outpacing both the 9.5% nationwide benchmark and the broader SA3 territory, Dianella - South's 16.2% expansion since the 2021 census establishes it as a regional frontrunner in population growth.

Net overseas migration served as the principal catalyst, generating roughly 84.1% of recent population additions, while interstate arrivals and natural increases likewise delivered positive contributions. Projections for each individual SA2 zone utilized by AreaSearch stem from the 2024 ABS/Geoscience Australia dataset using 2022 as its baseline. Whenever specific SA2 data is unavailable, or when evaluating population shifts beyond 2032 across all regions, age-cohort growth rates published by the ABS within its 2023 Greater Capital Region update (anchored to 2022 benchmarks) are incorporated. Looking forward, the locality is slated for population growth slightly beneath the national statistical median, tracking toward a net rise of 940 persons through to 2041 according to recent annual ERP data, which equates to an aggregate climb of 6.0% across the 16 years.

Jobs & IndustryEmployment Trends in Dianella - South

Table Chart PROFILE FAQ

8,403 residents of Dianella - South are employed, from a labour force of 8,673. Unemployment sits at 3.1%, with participation at 67.3%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.6% 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 11,728, about 78% 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

A highly qualified labor force characterizes Dianella - South, supported by strong participation in essential industries, an unemployment rate of merely 3.1%, and an estimated 3.8% rise in local jobs over the past year. By March 2026, employed residents reached 8,403, and local unemployment registered 1.1% lower than the 4.2% figure seen across Greater Perth, though labor participation trailed regional levels at 67.3% versus 69.9% across Greater Perth. Census records indicate that an 8.8% minority of workers operated from home, though pandemic restrictions during that period may have influenced figures.

Locals are predominantly employed across health care & social assistance, professional & technical, and education & training. Representation in professional & technical fields is particularly pronounced, tracking at 1.3 times the regional average. Conversely, mining accounts for a comparatively small share, engaging only 4.4% of working residents in Dianella - South relative to 7.0% across Greater Perth. Because the suburb is predominantly residential, local workplace opportunities within the boundary remain modest when comparing resident workers against the local job base. Employment and workforce figures for the year ending March 2026, as examined through AreaSearch using SALM and ABS data, show a 3.8% rise in both employment levels and the labour force, while unemployment stayed virtually the same. In contrast, Greater Perth experienced employment growth of 2.0% and labour force growth of 2.5%, accompanied by a 0.4 percentage point increase in unemployment. Jobs and Skills Australia’s national employment forecasts from Mar-26 provide additional perspective on anticipated future demand in Dianella - South. These outlooks span five and ten-year horizons and have been overlaid with the local employment composition to project growth trajectories. Nationally, employment is projected to grow by 6.6% over five years and by 13.7% over ten years, though sectoral growth rates vary considerably. When these industry-specific expectations are applied to Dianella - South’s current employment structure, the area is anticipated to see employment rise by 6.6% over five years and 13.7% over ten years, though this calculation represents a basic weighted extrapolation for illustrative use only and does not incorporate localized population forecasts.

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 — 185 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (12,985 at the 2021 Census → 15,088 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 (505021302). 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 Dianella - South 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 Dianella - South 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 Dianella - South 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.
