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 AreaSearch's analysis, Wanniassa's population is around 7,744 as of Feb 2026. 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 estimated resident population of 7,721 from the ABS as of June 2024 and an additional 42 validated new addresses since the Census date. This population level 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 the census, the SA3 area achieved 0.1% growth, highlighting divergent population trends. Population growth for the area was primarily driven by overseas migration, which contributed approximately 53.3% of overall population gains during recent periods.

AreaSearch adopts 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. Considering the projected demographic shifts, projections indicate a decline in overall population, with the area'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. See the age section for more details.

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 experienced around 12 dwellings receiving development approval each year, totalling 61 homes over the past 5 financial years. So far in FY-26, 4 approvals have been recorded. Given an average of only 0.4 new residents per year per dwelling constructed over the past 5 financial years (between FY-21 and FY-25), new supply is keeping pace with or exceeding demand, offering ample buyer choice and creating capacity for population growth beyond current forecasts, while new properties are constructed at an average value of $238,000. There have also been $4.4 million in commercial approvals this financial year, suggesting the area's residential character.

Compared to the Australian Capital Territory, Wanniassa shows approximately 67% of the construction activity per person while it places among the 27th percentile of areas assessed nationally, meaning somewhat limited buyer options while strengthening demand for established properties. This is likewise lower than nationally, reflecting market maturity and pointing to possible development constraints. New building activity shows 45.0% detached houses and 55.0% townhouses or apartments. This focus on higher-density living creates more affordable entry points and suits downsizers, investors, and first-home buyers. This shows a considerable change from the current housing mix (currently 90.0% houses), reflecting reduced availability of development sites and addressing shifting lifestyle demands and affordability requirements. At around 657 people per approval, Wanniassa shows a mature, established area.

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

Wanniassa shows employment indicators that trail behind approximately 70% of regions assessed across Australia

Wanniassa features a well-educated workforce, with essential services sectors well represented, an unemployment rate of 5.5%, and relative employment stability over the past year. As of December 2025, 3,973 residents are in work, while the unemployment rate is 1.7% above the Australian Capital Territory's rate of 3.8%, and workforce participation lags significantly (66.4% compared to the Australian Capital Territory's 72.6%). Based on Census responses, a low 11.7% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Leading employment industries among residents comprise public administration & safety, health care & social assistance, and education & training. Conversely, professional & technical services are under-represented, with only 8.7% of Wanniassa's workforce compared to 11.1% in the Australian Capital Territory. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, over the 12 months to December 2025, employment increased by 0.1% while the labour force increased by 0.9%, resulting in an unemployment rise of 0.8 percentage points. This compares to the Australian Capital Territory, where employment grew by 0.9%, the labour force expanded by 1.2%, and unemployment rose 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Wanniassa. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly 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 (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
