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

As of May 2026, the estimated population of the suburb of Wanniassa is around 7,741, reflecting a decrease of 144 people since the 2021 Census. This decrease represents a reduction of approximately 1.8%. The resident population was estimated at 7,731 by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 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, which is higher than the average seen across national locations assessed by AreaSearch. Overseas migration contributed approximately 53.0% of overall population gains during recent periods, driving primary growth for the area.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, age group growth rates from the ACT Government's SA2 area projections are adopted, using 2022 as the base year. Looking ahead, demographic trends indicate an overall population decline in the suburb over time. According to current methodology, the population is projected to decrease by 442 persons by 2041. However, growth is anticipated within specific age cohorts, notably with the 75 to 84 age group expected to expand by 143 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 seen approximately 12 new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Over the past 5 financial years, from FY-21 to FY-25, around 61 homes were approved, with a further 4 approved in FY-26 so far. On average, about 0.5 people moved to the area annually for each dwelling built over these years.

New construction is keeping pace with or exceeding demand, offering buyers more options and enabling population growth. The average expected construction cost value of new dwellings is $305,000. This financial year has seen $4.4 million in commercial approvals registered, indicating the area's residential character. Compared to the Australian Capital Territory, Wanniassa shows around 67% of the construction activity per person. Nationally, it ranks at the 28th percentile of areas assessed, suggesting somewhat limited buyer options while strengthening demand for established dwellings. This lower level of building activity reflects market maturity and possible development constraints.

New building activity in Wanniassa comprises approximately 46.0% detached houses and 54.0% attached dwellings. This trend toward denser development provides accessible entry options, appealing to downsizers, investors, and entry-level buyers. This marks a significant shift from existing housing patterns, which are currently 90.0% houses, indicating diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. With around 595 people per dwelling approval, Wanniassa reflects a highly mature market. Given stable or declining population forecasts, the area may experience less housing pressure in the future, creating favourable conditions for buyers.

Wanniassa has strong levels of nearby infrastructure activity, ranking in the top 40% nationally

Nine projects identified by AreaSearch are expected to impact the area significantly. These include modernisation of Wanniassa Hills Primary School, implementation of Erindale Group Centre Master Plan Stage 1, development of The Valley Ponds in Wanniassa, and expansion of Kambah Group Centre.

Employment performance in Wanniassa has been below expectations when compared to most other areas nationally

Wanniassa has a well-educated workforce with essential services sectors well represented. The unemployment rate was 5.5% as of December 2025, showing relative employment stability over the past year according to AreaSearch's statistical area data aggregation. As of this date, 3973 residents were employed while the unemployment rate was 1.7% higher than the Australian Capital Territory's rate of 3.8%.

Workforce participation was somewhat lower at 66.3%, compared to the ACT's 70.5%. Census responses indicated that only 11.7% of residents worked from home, though Covid-19 lockdown impacts should be considered. Key industries of employment among residents were public administration & safety, health care & social assistance, and education & training.

Conversely, professional & technical services showed lower representation at 8.7%, compared to the regional average of 11.1%. The predominantly residential area appeared to offer limited local employment opportunities, as indicated by the count of Census working population versus resident population. Between December 2024 and December 2025, employment levels increased by 0.1% while labour force rose by 0.9%, resulting in an unemployment rise of 0.8 percentage points. In comparison, the Australian Capital Territory saw employment growth of 0.9%, labour force expansion of 1.2%, and a 0.3 percentage point increase in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 offer further insight into potential future demand within Wanniassa. These projections, covering five and ten-year periods, suggest national employment will expand by 6.6% over five years and 13.7% over ten years, with varying growth rates between industry sectors. Applying these industry-specific projections to Wanniassa's employment mix suggests local employment should increase by 6.4% over five years and 13.3% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
