As of November 2025, the estimated population of Woronora Heights is around 2,862 people. This reflects a growth since the 2021 Census, which reported a population of 2,781. The current estimate was inferred from AreaSearch's validation of new addresses and examination of the latest ERP data release by the ABS in June 2024. This resulted in an estimated resident population of 2,830 for Woronora Heights. The suburb has a population density ratio of approximately 1,100 persons per square kilometer, which is comparable to averages seen across other locations assessed by AreaSearch. Woronora Heights' growth rate since the 2021 Census was 2.9%, exceeding the SA3 area's growth rate of 2.6%.

This makes it a growth leader in the region. Overseas migration contributed approximately 75% of overall population gains during recent periods, driving primary population growth. AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises the NSW State Government's SA2 level projections, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. According to these projections, over this period, the suburb's population is expected to decline overall, shrinking by 106 persons by 2041. However, growth across specific age cohorts is anticipated, with the 75 to 84 age group projected to grow by 109 people.

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

Over the past 5 financial years to FY-26, an estimated total of 1 home has been approved. In FY-26 so far, 0 approvals have been recorded. Population decline over recent years indicates adequate development activity relative to population change, benefiting buyers.

New homes are built at an average construction cost value of $620,000, higher than regional norms, reflecting quality-focused development. This financial year has seen $43,000 in commercial development approvals, demonstrating the area's residential nature. Compared to Greater Sydney, Woronora Heights records lower building activity.

Constrained new construction typically reinforces demand and pricing for existing homes, though recent years have shown increased building activity. The area's established nature is indicated by its level of building activity being below the national average, suggesting potential planning limitations. Stable or declining population forecasts may result in less housing pressure, creating favourable conditions for buyers.
