Warrimoo 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 Feb 2026, the estimated population of the suburb of Warrimoo is around 2,497, reflecting a growth of 45 people since the 2021 Census. This increase represents an 1.8% rise from the previous population count of 2,452. AreaSearch's analysis, based on the latest ERP data release by the ABS in June 2024 and validated new addresses, indicates a resident population of 2,490. Overseas migration contributed approximately 53.0% to Warrimoo's overall population gains during recent periods. This level of population results in a density ratio of 291 persons per square kilometer, offering significant space per person and potential room for further development. Notably, Warrimoo's growth since the 2021 census exceeded that of its SA3 area (1.7%), positioning it as a growth leader in the region.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. According to this methodology, projections indicate a decline in overall population by 55 persons by 2041. However, growth across specific age cohorts is anticipated, with the 85 and over age group projected to increase by 87 people.

The level of residential development activity in Warrimoo is very low in comparison to the average area assessed nationally by AreaSearch

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Warrimoo averaged around 2 new dwelling approvals annually over the past 5 financial years, totalling an estimated 10 homes. As of FY-26 so far, 2 approvals have been recorded. The area has experienced population decline, with new supply likely keeping up with demand and offering good choice to buyers. New homes are being built at an average expected construction cost value of $501,000, indicating developers focus on the premium market with high-end developments.

This financial year, $1.6 million in commercial development approvals have been recorded, reflecting the area's residential nature. Compared to Greater Sydney, Warrimoo has significantly less development activity (60.0% below regional average per person), which generally supports stronger demand and values for established homes. This level is also below average nationally, suggesting the area's maturity and possible planning constraints. New building activity shows 67.0% detached houses and 33.0% medium and high-density housing, indicating an expanding range of medium-density options creating a mix of opportunities across price brackets. This reflects a considerable change from the current housing mix (currently 99.0% houses), likely due to reduced availability of development sites and shifting lifestyle demands and affordability requirements. The estimated count of 1237 people in the area per dwelling approval reflects its quiet, low activity development environment.

Population projections show stability or decline, suggesting Warrimoo should see reduced housing demand pressures, benefiting potential buyers.
