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

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since Feb 2026, the suburb of Wanniassa's population is estimated at around 7,744. This reflects a decrease of 141 people (1.8%) since the 2021 Census, which reported a population of 7,885 people. The change is inferred from the resident population of 7,721, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 42 validated new addresses since the Census date. This level of population equates to a density ratio of 1,434 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. While Wanniassa experienced a 1.8% decline since census, the SA3 area achieved 0.1% growth, highlighting divergent population trends. Population growth for the area was primarily driven by overseas migration that contributed approximately 53.0% 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 for years post-2032, age group growth rates from the ACT Government's SA2 area projections, with 2022 as a base, are adopted. As we examine future population trends, projections indicate a decline in overall population, with the suburb of Wanniassa's population expected to contract by 496 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, which is projected to increase 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

Between FY21-FY25, Wanniassa averaged 12 new dwelling approvals per year. From FY21 to FY26 Q1, around 65 dwellings were approved. This results in approximately 0.4 new residents per year per dwelling constructed over the past five financial years.

The average construction value of these dwellings is $305,000. In FY26 up until now, $4.4 million in commercial approvals have been registered. Compared to the Australian Capital Territory, Wanniassa has around two-thirds the rate of new dwelling approvals per person and ranks among the 28th percentile nationally. The breakdown of new building activity shows 46.0% standalone homes and 54.0% attached dwellings. With approximately 595 people per dwelling approval, Wanniassa indicates a highly mature market with stable or declining population expected in the future.

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

Wanniassa has an educated workforce with significant representation in essential services sectors. The unemployment rate was 5.2% as of September 2025, with an estimated employment growth of 0.6% over the past year. There are currently 3,979 residents employed.

Compared to the Australian Capital Territory's (ACT) rate of 3.6%, Wanniassa's unemployment rate is 1.7% higher. Workforce participation in Wanniassa lags behind ACT at 66.2% compared to ACT's 72.5%. According to Census responses, only 11.7% of residents work from home.

The key industries for employment among residents are public administration & safety, health care & social assistance, and education & training. Professional & technical services have limited presence with 8.7% employment compared to the regional average of 11.1%. Employment opportunities locally may be limited as indicated by the difference between Census working population and resident population. Between September 2024 and September 2025, employment levels increased by 0.6%, labour force grew by 0.8%, resulting in an unemployment rise of 0.2 percentage points. In contrast, ACT recorded employment growth of 1.4% and a reduction in unemployment by 0.2 percentage points during the same period. Jobs and Skills Australia's national employment forecasts from May-25 project a 6.6% expansion over five years and 13.7% over ten years for national employment. Applying these projections to Wanniassa's employment mix suggests local employment should increase by approximately 6.4% over five years and 13.3% over ten years, though this is a simplified extrapolation for illustrative purposes only and does not account for localized population projections.
