Detail
As of Aug 2026, the suburb of Dianella has an estimated population of approximately 26,753, according to AreaSearch's evaluation of regional ABS updates and post-Census validated addresses. Compared to the 24,169 residents recorded in the 2021 Census, this indicates an addition of 2,584 people (10.7%). The updated figure builds upon the June 2025 ABS ERP release of 26,719 inhabitants alongside 220 post-Census validated new addresses. With a population density of 2,491 persons per square kilometer, the suburb of Dianella sits within the upper quartile of nationally assessed regions. Its 10.7% expansion rate since the 2021 census outstripped the national mark of 9.5%, positioning it among the region's faster-growing localities.
Overseas migration served as the primary growth driver, accounting for roughly 87.0% of recent population additions. Projections for the suburb of Dianella draw on 2024 ABS/Geoscience Australia SA2 modeling with a 2022 baseline, supplemented for post-2032 horizons and uncovered zones by the 2023 ABS Greater Capital Region age-cohort projections (also utilizing 2022 data). Demographic trajectories point to an expansion rate tracking slightly beneath the national statistical area median, anticipating that the suburb of Dianella will add 2,722 persons by 2041 across aggregated SA2 boundaries, representing an overall rise of 10.1% across the 16 years.
Frequently Asked Questions - Population
456 new dwellings have been approved in Dianella over the past five years, an average of 91 a year. That places the area in the 82nd percentile for residential development activity nationally, about 3 approvals per 1,000 residents a year. Of the 82 dwellings approved in the latest reporting year, 78% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 106, broadly in line with 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
Over the past 5 financial years, the locality has averaged roughly 91 residential approvals per annum, representing an aggregate of 456 dwellings based on AreaSearch's review of ABS building approval records. In FY-25 to date, 106 building permits have been granted. Between FY-21 and FY-25, the area attracted an average of 4.4 incoming residents per constructed home annually, creating a notable imbalance where demand outpaces new supply—a dynamic commonly associated with heightened buyer competition and upward pricing pressure. New builds carry an average estimated construction value of $548,000, marginally exceeding regional benchmarks and highlighting an emphasis on higher-end builds.
Commercial development activity has been comparatively subdued, with approvals totaling $5.2 million for the current financial year. Recent residential building activity is weighted toward traditional detached houses at 78.0%, while medium and high-density housing comprises 22.0%, preserving established suburban neighborhood appeal for buyers seeking standalone homes. With approximately 262 people per approval, the local development pipeline characterizes an evolving residential market. Long-term projections indicate the area is set to add 2,688 residents leading up to 2041 based on the most recent AreaSearch quarterly figures. Although current construction levels are tracking reasonably against anticipated growth, intensifying population expansion could lead to heightened competition among prospective home purchasers.

Dianella Apartments
128-unit apartment development by Finbar Group, completed in 2021. Four low-rise buildings around a central courtyard with resort-style amenities including a 20 m pool, residents lounge, gym, games room, cabana and BBQ areas.
14,818 residents of Dianella are employed, from a labour force of 15,289. Unemployment sits at 3.1%, with participation at 66.8%. 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. The working-day population is estimated at 21,348, about 80% 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
The local labour market features an educated workforce and strong representation across essential services, marked by an unemployment rate of just 3.1% alongside 3.4% estimated employment growth over the preceding year according to AreaSearch aggregated data. In March 2026, employed residents numbered 14,818, with local unemployment sitting 1.1% below the 4.2% figure for Greater Perth. The participation rate recorded 66.8%, which trails the wider Greater Perth level of 69.9%. Census figures showed 8.9% of local workers operating from home, though this metric was captured during Covid-19 lockdown conditions. The primary employment sectors for local residents include health care & social assistance, retail trade, and professional & technical services.
Conversely, the mining sector accounts for only 4.1% of local workers, in contrast to 7.0% across Greater Perth. As reflected in the disparity between the resident labour force and local Census workplace counts, this largely suburban community provides relatively few jobs within its own borders. According to AreaSearch analysis of ABS and SALM figures aggregated across wider statistical areas, the 12-month period generated a 3.4% rise in employment alongside a 3.5% expansion in the labour pool, nudging the local jobless rate up by 0.1 percentage points. Across Greater Perth over the same timeframe, employment climbed 2.0% and the workforce increased 2.5%, with unemployment edging up 0.4 percentage points. Mar-26 Jobs and Skills Australia national forecasts project workforce growth of 6.6% over five years and 13.7% over ten years across the country, though sector trends vary. Weighting these industry projections against the local employment profile suggests potential local workforce expansion of 6.6% across five years and 13.6% across ten years, representing an illustrative industry-weighted extrapolation rather than a local demographic forecast.

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 — 220 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (24,169 at the 2021 Census → 26,753 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.
