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, as of November 2025, is approximately 7,742, a decrease of 143 people since the 2021 Census which recorded 7,885 residents. This decline, amounting to 1.8%, is inferred from ABS estimated resident population data for June 2024 (7,727) and validated new addresses since the Census date. The population density is approximately 1,433 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. While Wanniassa experienced a decline of 1.8% since the census, the SA3 area showed a growth of 0.2%, indicating divergent trends. Overseas migration contributed around 53.3% of overall population gains in recent periods for the area. 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, age group growth rates from ACT Government's SA2 area projections (base year 2022) are adopted. Projections indicate a decline of 496 persons by 2041, with specific age cohorts expected to grow, notably the 75 to 84 age group 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

Wanniassa has received approximately 12 dwelling approvals annually over the past five financial years, totalling 61 homes. As of FY-26, 4 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 has kept pace with or exceeded demand, providing ample buyer choice and capacity for population growth beyond current forecasts. New properties are constructed at an average expected cost of $238,000.

This financial year has seen $4.4 million in commercial approvals, suggesting 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 27th percentile nationally, indicating somewhat limited buyer options while strengthening demand for established properties. This reflects market maturity and possible development constraints. New building activity comprises 45.0% detached houses and 55.0% townhouses or apartments, creating more affordable entry points and suiting downsizers, investors, and first-home buyers. This shift from the current housing mix of 90.0% houses reflects reduced availability of development sites and addresses shifting lifestyle demands and affordability requirements. With approximately 657 people per approval, Wanniassa is 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.

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

Wanniassa has an educated workforce with prominent representation in essential services sectors. The unemployment rate was 5.2% as of September 2025, with estimated employment growth of 0.6% over the previous year.

In this month, 3979 residents were employed while the unemployment rate was 1.7 percentage points higher than the Australian Capital Territory's (ACT) rate of 3.6%. Workforce participation was lower at 64.9%, compared to ACT's 69.6%. Key employment industries for residents included public administration & safety, health care & social assistance, and education & training.

However, professional & technical services were under-represented with only 8.7% of Wanniassa's workforce compared to ACT's 11.1%. The area offers limited local employment opportunities as indicated by the difference between Census working population and resident population. From September 2024 to September 2025, employment increased by 0.6%, labour force grew by 0.8%, resulting in unemployment rising by 0.2 percentage points. In contrast, ACT saw employment grow by 1.4%, labour force expand by 1.2%, and unemployment fall by 0.2 percentage points. As of 25-Nov-25, ACT's employment grew by 1.19% year-on-year with an addition of 710 jobs, while the state unemployment rate was 4.5%. National employment forecasts from May-25 indicate a projected growth of 6.6% over five years and 13.7% over ten years. Applying these 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 an illustrative extrapolation not accounting for localized population projections.
