Dianella - North

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

Based on AreaSearch's analysis, Dianella - North's population is around 12,689 as of Feb 2026. This reflects an increase of 762 people (6.4%) since the 2021 Census, which reported a population of 11,927 people. The change is inferred from the estimated resident population of 12,684 from the ABS as of June 2024 and an additional 115 validated new addresses since the Census date. This population level equates to a density ratio of 1,961 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Population growth for the area was primarily driven by overseas migration, which was essentially the sole driver of 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). Regarding demographic trends, an above-median population growth of statistical areas analysed by AreaSearch is projected, with the area expected to grow by 2,203 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 17.3% in total over the 17 years.

Residential development activity is slightly higher than average within Dianella - North when compared nationally

Dianella - North has recorded around 35 residential properties granted approval per year, totalling 177 homes over the past 5 financial years. So far in FY-26, 22 approvals have been recorded. With an average of 2.9 new residents per year gained for each dwelling built over the past 5 financial years (between FY-21 and FY-25), indicating healthy demand that should support property values, new homes are being built at an average value of $328,000. Additionally, $4.9 million in commercial approvals have been registered this financial year, demonstrating the area's primarily residential nature.

Compared to Greater Perth, Dianella - North records about 65% of the building activity per person, placing it among the 44th percentile of areas assessed nationally. This results in relatively constrained buyer choice, supporting interest in existing dwellings. This activity is also below average nationally, reflecting the area's maturity and pointing to possible planning constraints. New building activity consists of 86.0% standalone homes and 14.0% townhouses or apartments, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. At around 398 people per approval, Dianella - North indicates a mature market.

Population forecasts indicate Dianella - North will gain 2,198 residents through to 2041 (from the latest AreaSearch quarterly estimate). At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.

As of December 2025, 6,970 residents are in work, while the unemployment rate is 1.0% below Greater Perth's rate of 4.1%, and workforce participation lags significantly (66.5% compared to Greater Perth's 71.9%). Based on Census responses, a low 8.8% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

The key industries of employment among residents are health care & social assistance, retail trade, and construction.

On the other hand, mining is under-represented, with only 3.7% of Dianella - North's workforce compared to 7.0% in Greater Perth. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, over the 12 months to December 2025, employment increased by 4.3% while the labour force increased by 4.1%, resulting in unemployment falling by 0.2 percentage points. In contrast, Greater Perth experienced employment growth of 2.3% and labour force growth of 2.6%, with a 0.3 percentage point rise. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Dianella - North. 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 - North's employment mix suggests local employment should increase by 6.5% over five years and 13.5% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
