Woronora Heights

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

Based on ABS population updates and AreaSearch validation, the suburb of Woronora Heights' population is estimated at around 2915 as of February 2026. This reflects an increase of 134 people since the 2021 Census, which reported a population of 2781. The change is inferred from AreaSearch's estimate of 2830 residents following examination of ABS's latest ERP data release in June 2024 and address validation since the Census date. This level of population equates to a density ratio of 1121 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. Woronora Heights' growth of 4.8% since the 2021 census exceeded both the SA3 area (3.1%) and the SA4 region, marking it as a growth leader in the region. Population growth was primarily driven by overseas migration contributing 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 107 persons by 2041. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, projected to grow by 107 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 had minimal development with just two approvals over the five years from 2016 to 2021. This reflects a fully developed suburb with limited opportunities for new construction. The absence of new supply generally supports demand for established properties and can contribute to price stability.

When measured against Greater Sydney, Woronora Heights shows substantially reduced construction activity. This scarcity of new dwellings typically strengthens demand and prices for existing properties, though construction activity has intensified recently. This is likewise lower than nationally, reflecting market maturity and pointing to possible development constraints.

Given stable or declining population forecasts until 2036, Woronora Heights may experience less housing pressure, creating favourable conditions for buyers.
