Warrimoo

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, Warrimoo's population is estimated at around 2,497, reflecting an increase of 45 people since the 2021 Census which reported a population of 2,452. This growth is inferred from AreaSearch's estimation of the resident population as 2,490 following examination of the latest ERP data release by the ABS in June 2024 and an additional validated new address since the Census date. The suburb's population density is approximately 291 persons per square kilometer. Warrimoo's growth rate of 1.8% since the 2021 census exceeded that of the SA3 area at 1.7%. Overseas migration contributed around 53.0% of overall population gains in recent periods. AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections where applicable, released in 2022 with a base year of 2021.

For the years 2032 to 2041, projections indicate an overall population decline of 63 persons by 2041. However, specific age cohorts are expected to grow, notably the 85 and over age group which is projected to increase by 86 people.

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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Warrimoo has averaged around 2 new dwelling approvals annually over the past five financial years ending June 30, totalling an estimated 11 homes. So far in the financial year 2026 (FY-26), 1 approval has been recorded. The area's population decline suggests that new supply is likely meeting demand, providing good choice for buyers. New homes are being built at an average expected construction cost value of $501,000, indicating a focus on the premium market with high-end developments.

This financial year, $1.6 million in commercial development approvals have been recorded, reflecting Warrimoo's residential nature. Compared to Greater Sydney, Warrimoo has significantly less development activity, 56.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established homes. Nationally, Warrimoo's level of development is also below average, possibly due to planning constraints. New building activity shows 67.0% detached houses and 33.0% medium and high-density housing, expanding the range of medium-density options and creating a mix of opportunities across price brackets. This represents a significant change from the current housing mix, which is currently 99.0% houses.

The estimated count of 989 people in the area per dwelling approval reflects Warrimoo's quiet, low activity development environment. With population projections showing stability or decline, Warrimoo should see reduced housing demand pressures, benefiting potential buyers.
