Dianella

An assessment of population growth drivers in Dianella reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on evaluation of ABS updates for the region and new locations confirmed by AreaSearch post-Census, Dianella's population is estimated at around 26,735 as of May 2026. This represents an increase of 2,566 people (10.6%) compared to the 2021 Census, which counted 24,169 people. The adjustment is derived from the resident population of 26,719, estimated by AreaSearch after reviewing the latest ERP data release from the ABS (June 2025) and an additional 220 validated new addresses since the Census date. This population level translates to a density ratio of 2,489 persons per square kilometer, placing the area in the upper quartile of national locations assessed by AreaSearch. Dianella's 10.6% growth rate since the 2021 census outperformed the national average (9.3%), establishing it as a growth leader in the region. Population growth for the area was primarily driven by overseas migration, which accounted for approximately 87.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and to estimate growth across all areas in the years post-2032, AreaSearch is utilising the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). Anticipating future population dynamics, a population increase just below the median of statistical areas analysed by AreaSearch is expected, with the area expected to increase by 2,872 persons to 2041 based on aggregated SA2-level projections, reflecting with an increase of 10.7% in total over the 16 years.

AreaSearch assessment of residential development activity positions Dianella among the top 25% of areas assessed nationwide

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, the suburb of Dianella has averaged around 88 new dwelling approvals each year, with an estimated 443 homes approved over the past 5 financial years (between FY-21 and FY-25) and 94 so far in FY-26. At an average of 4 new residents per year for every home built over the past 5 financial years (between FY-21 and FY-25), demand is significantly outpacing supply, which typically puts upward pressure on prices and increases competition among buyers, while new dwellings are developed at an average value of $474,000, revealing that developers are targeting the premium market segment with higher-end properties. There have also been $5.2 million in commercial approvals this financial year, demonstrating the area's primarily residential nature.

New development consists of 82.0% detached houses and 18.0% medium and high-density housing, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. The location has approximately 327 people per dwelling approval, indicating room for growth.

Population forecasts indicate Dianella will gain 2,856 residents through to 2041 (from the latest AreaSearch quarterly estimate). Construction is maintaining a reasonable pace with projected growth, although buyers could encounter growing competition as population increases.

AreaSearch analysis places Dianella well above average for employment performance across multiple indicators

Dianella has a well-educated workforce, with essential services sectors well represented, an unemployment rate of only 3.1%, and 3.4% in estimated employment growth over the past year, based on AreaSearch aggregation of statistical area data. As of March 2026, 14,817 residents are in work while the unemployment rate is 1.1% below Greater Perth's rate of 4.2%, and workforce participation is somewhat below standard (66.8% compared to Greater Perth's 70.2%). Based on Census responses, a low 8.9% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Employment among residents is concentrated in health care & social assistance, retail trade, and professional & technical. Conversely, mining shows lower representation at 4.1% versus the regional average of 7.0%. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of Census working population vs resident population.

Based on AreaSearch analysis of SALM and ABS data, aggregated from broader statistical areas, the 12-month period saw employment increasing by 3.4% alongside labour force increasing by 3.5%, with unemployment remaining essentially unchanged. This contrasts with Greater Perth, where employment rose by 2.0%, the labour force grew by 2.5%, and unemployment rose 0.4 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Dianella. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Dianella's employment mix suggests local employment should increase by 6.6% over five years and 13.6% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
