According to evaluations by AreaSearch, the population of Dianella - North is estimated at approximately 12,842 in May 2026. This represents a gain of 915 residents (7.7%) compared to the 2021 Census, which recorded 11,927 people.

The post-census growth of 7.7% in Dianella - North is within 1.6 percentage points of the 9.3% national average, showing stable demographic momentum. This growth was almost entirely powered by net gains from overseas migration, which served as the exclusive contributor to population expansion in recent times.

AreaSearch utilizes projections from the ABS and Geoscience Australia released in 2024, using 2022 as the baseline year. For regions missing these projections or to project trends past 2032, growth rates by age bracket from the 2023 Greater Capital Region forecasts (based on 2022 data) are applied. Looking at future demographic patterns, the area is projected to experience population growth above the median of locations tracked by AreaSearch. Based on the most recent annual ERP data, the population is set to expand by 1,992 individuals by 2041, representing a total increase of 15.5% over the 16-year projection window.

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

Dianella - North has registered an average of approximately 35 new residential approvals annually, with 177 dwellings approved throughout the 5 financial years from FY-21 to FY-25, and 31 recorded so far in FY-26. An average of 2.9 additional residents was added for every new home constructed over the 5 financial years from FY-21 to FY-25, pointing to healthy demand levels that should underpin residential values. These new dwellings carry an average construction value of $328,000. Additionally, commercial building approvals have reached $4.9 million this financial year, reinforcing the predominantly residential profile of the neighborhood.

In comparison to the broader Greater Perth region, per capita construction activity in Dianella - North is at roughly 65% of the regional level, placing it in the 44th percentile of areas evaluated nationwide. This leads to a comparatively restricted selection of new properties, which supports demand for established homes. This level of activity is below the national average, reflecting a mature suburb that may be subject to planning constraints. The mix of new construction consists of 86.0% detached houses and 14.0% multi-dwelling units or townhouses, reinforcing the classic suburban profile of the area with a preference for family-oriented housing offering space. With roughly 403 residents for each new approval, the local property market shows characteristics of maturity.

Long-term projections indicate that Dianella - North will add 1,990 inhabitants by 2041, according to the latest quarterly estimates from AreaSearch. If the current pace of construction persists, the supply of new dwellings may struggle to accommodate the growing population, potentially driving up competition among buyers and supporting upward pressure on property prices.

These projections, which span five and ten-year horizons, have been aligned with the local employment profile to estimate growth patterns. National employment is projected to expand by 6.6% over five years and 13.7% over ten years, though growth rates vary considerably across different industry sectors. When these industry-specific projections are applied to Dianella - North's employment mix, local employment is expected to rise by 6.5% over five years and 13.5% over ten years, with the caveat that this represents a simple weighting extrapolation for illustrative purposes and does not incorporate localised population projections.
