Dianella

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

As of Nov 2025, the estimated population of the Dianella statistical area (Lv2) is around 26,118. This reflects an increase of 1,949 people since the 2021 Census, which reported a population of 24,169. The change was inferred from the resident population of 26,102 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 224 validated new addresses since the Census date. This level of population equates to a density ratio of 2,431 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. The Dianella (SA2)'s 8.1% growth since census positions it within 1.6 percentage points of the national average (9.7%), demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by overseas migration that contributed 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). Looking at population projections moving forward, a population increase just below the median of Australian statistical areas is expected. The area is expected to grow by 3,121 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 13.3% in total over the 17 years.

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

AreaSearch analysis shows Dianella averaged around 83 new dwelling approvals per year. Between FY-21 and FY-25, approximately 419 homes were approved, with another 39 so far in FY-26. This results in about 4.5 new residents arriving annually per dwelling constructed over the past five financial years.

Supply has not kept pace with demand, which can put upward pressure on prices and increase competition among buyers. The average construction value of new properties is $475,000, indicating a focus on premium segment dwellings.

This year, there have been $5.2 million in commercial approvals, reflecting Dianella's primarily residential nature. Recent construction comprises 82.0% detached houses and 18.0% townhouses or apartments, maintaining the area's suburban character with a focus on family homes. The location has approximately 393 people per dwelling approval, indicating an established area. Looking ahead, Dianella is projected to grow by 3,464 residents through to 2041. Development is keeping pace with projected growth, though increasing competition among buyers may result from population expansion.
