Wanniassa

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 is approximately 7,742 as of November 2025. This shows a decrease of 143 people from the 2021 Census figure of 7,885, indicating a 1.8% decline since then. The change was inferred using the estimated resident population of 7,727 in June 2024 and an additional 42 validated new addresses since the Census date. This results in a population density ratio of 1,433 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. While Wanniassa experienced this decline, the SA3 area as a whole saw a growth of 0.2%, highlighting differing trends within the region. Population growth was primarily driven by overseas migration, contributing about 53.3% of overall population gains in recent periods.

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

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 received approximately 12 dwelling approvals annually over the past five financial years, totalling 61 homes. As of FY-26, 3 approvals have been recorded. The average new resident per year per dwelling constructed between FY-21 and FY-25 is 0.4, indicating that supply is meeting or exceeding demand, providing ample buyer choice and capacity for population growth. New properties are being constructed at an average expected cost of $305,000.

In FY-26, there have been $4.4 million in commercial approvals, suggesting the area's residential character. Compared to the Australian Capital Territory, Wanniassa shows around 67% of construction activity per person and ranks among the 27th percentile nationally, indicating somewhat limited buyer options while strengthening demand for established properties. New building activity comprises approximately 45.0% detached houses and 55.0% townhouses or apartments, reflecting a shift towards higher-density living to suit downsizers, investors, and first-home buyers. This change is notable given the current housing mix of 90.0% houses, likely due to reduced development site availability and shifting lifestyle demands and affordability requirements. With around 657 people per approval, Wanniassa shows a mature, established area with an expected stable or declining population, potentially reducing pressure on housing and creating buying opportunities.

With population expected to remain stable or decline, Wanniassa should see reduced pressure on housing, potentially creating opportunities for buyers.
