Wanniassa
Statistical Area - sa2

Wanniassa is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Wanniassa's population, as per AreaSearch's analysis, was approximately 7,735 by August 2025. This figure represents a decrease of 150 individuals (1.9%) since the 2021 Census, which recorded a population of 7,885. The change is inferred from ABS's estimated resident population of 7,728 in June 2024 and an additional 39 validated new addresses since the Census date. This results in a population density ratio of 1,432 persons per square kilometer, exceeding national averages assessed by AreaSearch. While Wanniassa saw a 1.9% decline from census to August 2025, the SA3 area experienced a 0.2% growth, indicating differing population trends. Overseas migration contributed approximately 53.3% of overall population gains in recent periods for the area.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data and years post-2032, age group growth rates from ACT Government's SA2 area projections are adopted, using 2022 as a base. Future demographic trends indicate an overall population decline of 496 persons by 2041, with specific age cohorts expected to grow. Notably, the 75 to 84 age group is projected to increase by 195 people over this period.

AreaSearch assessment of residential development drivers sees a low level of activity in Wanniassa, placing the area among the bottom 25% of areas assessed nationally

Wanniassa has recorded approximately 12 residential properties granted approval each year. Over the past five financial years, from FY-21 to FY-25, 61 homes were approved, with another 3 approved so far in FY-26. On average, about 0.4 people have moved to the area per dwelling built over these years, indicating that new supply is meeting or exceeding demand and providing ample buyer choice while allowing for population growth beyond current forecasts.

The average construction cost value of new properties is $305,000. This year alone, $4.4 million in commercial development approvals have been recorded, suggesting the area's residential character. Compared to the Australian Capital Territory, Wanniassa shows around 67% of the construction activity per person and ranks among the 28th percentile of areas assessed nationally. This results in relatively constrained buyer choice and supports interest in existing properties. The new development consists of 45.0% detached houses and 55.0% medium to high-density housing, indicating a shift from the area's current housing stock, which is predominantly houses (90.0%). This trend may reflect decreasing availability of developable sites and changing lifestyles that require more diverse and affordable housing options.

Wanniassa has around 657 people per approval, suggesting a mature and established area with an expected stable or declining population. Consequently, there should be reduced pressure on housing in the future, potentially creating opportunities for buyers.
