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 of August 2025, is approximately 7,735, a decrease of 150 people from the 2021 Census figure of 7,885. This decline reflects an estimated resident population of 7,728 in June 2024 and 39 new addresses validated since the Census date. The population density is around 1,432 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. While Wanniassa's population decreased by 1.9% since the census, the SA3 area experienced a 0.2% growth, showing divergent trends. Overseas migration contributed about 53.3% of overall population gains recently. AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year.

For areas not covered and years post-2032, ACT Government's SA2 area projections with a 2022 base are adopted. By 2041, the population is projected to decline by 496 persons, but specific age cohorts like the 75 to 84 group are expected to grow by 195 people.

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 an additional 3 approved so far in FY-26. The average number of people moving to the area per dwelling built over these years is 0.4.

New supply has kept pace with or exceeded demand, offering ample buyer choice and capacity for population growth beyond current forecasts. The average construction value of new properties is $305,000. This financial year, $4.4 million in commercial development approvals have been recorded, reflecting the area's residential character. Compared to the Australian Capital Territory, Wanniassa shows approximately 67% of the construction activity per person and ranks among the 28th percentile nationally, indicating relatively constrained buyer choice and supporting interest in existing properties. This level is below the national average, suggesting the area's established nature and potential planning limitations. New development consists of 45.0% detached houses and 55.0% medium and high-density housing, providing accessible entry options for downsizers, investors, and entry-level buyers.

This shift from the area's existing housing composition (currently 90.0% houses) reflects decreasing availability of developable sites and changing lifestyles requiring more diverse, affordable housing options. With around 657 people per approval, Wanniassa is a mature, established area with an expected stable or declining population, potentially reducing pressure on housing and creating opportunities for buyers.

Meanwhile, ACT saw employment rise by 1.9% with a labour force growth of 1.6%, leading to a decrease in unemployment by 0.3 percentage points. As of Sep-25, ACT's employment contracted by 0.33% (losing 1,480 jobs), with an unemployment rate of 4.2%. Nationally, the unemployment rate is 4.5%, with employment growth at 0.26%. Jobs and Skills Australia's national employment forecasts from May 2025 project a 6.6% expansion over five years and 13.7% over ten years. Applying these projections to Wanniassa's employment mix suggests local growth of approximately 6.4% over five years and 13.3% over ten years, though this is a simplified extrapolation for illustrative purposes and does not account for localised population projections.
