Woronora Heights

Woronora Heights has shown very soft population growth performance across periods assessed by AreaSearch

As of Feb 2026, the population of Woronora Heights is estimated at around 2,915. This reflects an increase of 134 people since the 2021 Census, which reported a population of 2,781. The change is inferred from AreaSearch's estimation of the resident population at 2,830 following examination of the latest ERP data release by the ABS in June 2024 and address validation since the Census date. This level of population equates to a density ratio of 1,121 persons per square kilometer. The suburb's 4.8% growth since the 2021 census exceeded both the SA3 area (3.1%) and the SA4 region, marking it as a growth leader in the region. Overseas migration contributed approximately 75.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections, 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. Over this period, projections indicate a decline in overall population, with the suburb's population expected to shrink by 109 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 grow by 105 people.

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

The absence of new supply typically supports demand for established properties and contributes to price stability when compared to Greater Sydney.

Measured against national averages, Woronora Heights shows substantially reduced construction levels, reflecting its maturity and possible planning constraints. Population projections indicate stability or decline in the area, suggesting reduced housing demand pressures that could benefit potential buyers.
