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, a population increase just below the median of national statistical areas is expected, with the area expected to grow by 1,104 persons to 2041 based on the latest annual ERP population numbers, reflecting a gain of 7.5% in total over the 17 years.

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

Dianella - South has seen around 59 new homes approved each year, totalling 299 homes over the past 5 financial years. So far in FY-26, 37 approvals have been recorded. At an average of 4.7 new residents per year for every home built over the past 5 financial years (between FY-21 and FY-25), supply is substantially lagging demand, which generally means heightened buyer competition, leading to pricing pressures, while new homes are being built at an average value of $303,000. There have also been $406,000 in commercial approvals this financial year, indicating minimal commercial development activity.

When measured against Greater Perth, Dianella - South shows comparable new home approvals (per person), supporting market stability in line with regional patterns. New development consists of 80.0% standalone homes and 20.0% attached dwellings, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. New construction favours detached housing more than current patterns suggest (61.0% at Census), demonstrating ongoing robust demand for family homes despite increasing density pressures. With around 283 people per dwelling approval, Dianella - South shows a developing market.

Population forecasts indicate Dianella - South will gain 1,096 residents through to 2041 (from the latest AreaSearch quarterly estimate). With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
