Based on AreaSearch's analysis, Woronora Heights's population is around 3,706 as of Feb 2026. This reflects an increase of 167 people (4.7%) since the 2021 Census, which reported a population of 3,539 people. The change is inferred from the estimated resident population of 3,598 from the ABS as of June 2024 and an additional 21 validated new addresses since the Census date. This population level equates to a density ratio of 1,180 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. Woronora Heights's 4.7% growth since the 2021 census exceeded the SA3 area (3.1%) and the SA4 region, marking it as a growth leader in the region. Population growth for the area was primarily driven by overseas migration, which contributed approximately 75.0% 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, AreaSearch utilizes the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Regarding demographic trends, projections indicate a decline in overall population, with the area's population expected to contract by 129 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 expand by 143 people.

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

Woronora Heights has averaged around 1 new dwelling approval each year, totalling 7 homes over the past 5 financial years. So far in FY-26, 0 approvals have been recorded. Given the population has fallen over the past period, new supply has likely been keeping up with demand, offering good choice to buyers, while new homes are being built at an average value of $230,000—below regional norms—reflecting more affordable housing options for purchasers. Additionally, $273,000 in commercial development approvals have been recorded this financial year, suggesting a predominantly residential focus.

Relative to Greater Sydney, Woronora Heights has significantly less development activity (88.0% below regional average per person). This scarcity of new homes typically strengthens demand and prices for existing properties. This is also below average nationally, reflecting the area's maturity and pointing to possible planning constraints. Further, recent development has been entirely comprised of detached dwellings, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space.

With population projections showing stability or decline, Woronora Heights should see reduced housing demand pressures, benefiting potential buyers.
