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 ABS population updates and AreaSearch validations, as of Nov 2025, Wanniassa's estimated population is around 7,744. This reflects a decrease from the 2021 Census figure of 7,885 people, a change inferred from AreaSearch's estimation of 7,721 residents following examination of ABS ERP data release in June 2024 and additional validated new addresses since the Census date. This results in a population density ratio of 1,434 persons per square kilometer, above national averages assessed by AreaSearch. While Wanniassa experienced a 1.8% decline since census, the SA3 area achieved 0.1% growth. Overseas migration contributed approximately 53.0% of overall population gains during recent periods. AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area released in 2024 with 2022 as the base year.

For areas not covered by this data and years post-2032, age group growth rates from ACT Government's SA2 area projections are adopted. Future population trends indicate a decline of 496 persons by 2041, led by an increase in the 75 to 84 age group projected at 195 people.
