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

As of August 2025, Woronora Heights' population is approximately 3,636, reflecting a 97-person increase from the 2021 Census figure of 3,539. This growth represents a 2.7% rise since the census date, inferred from ABS estimates and address validation up to June 2024. The population density is around 1,158 persons per square kilometer, comparable with averages across locations assessed by AreaSearch. Woronora Heights' 2.7% growth rate exceeded that of its SA3 area (2.5%), indicating it as a growth leader in the region. Overseas migration contributed approximately 75.0% of overall population gains during recent periods. AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022.

For areas not covered by this data, NSW State Government's SA2 level projections are utilized, 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, Woronora Heights' population is expected to decline overall by 129 persons by 2041. However, specific age cohorts are anticipated to grow, notably the 75-84 age group, which is projected to expand by 143 people over this period.

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 approximately one new dwelling approval per year. Development approval data from the Australian Bureau of Statistics (ABS) for the past five financial years, from FY21 to FY25, totals seven approvals. No approvals have been recorded so far in FY26. The population decline in recent years suggests that new supply has likely kept pace with demand, providing good choices for buyers.

The average expected construction cost value of new dwellings is $620,000, which is moderately above regional levels, indicating a focus on quality construction. This financial year has seen $273,000 in commercial approvals, suggesting minimal commercial development activity compared to Greater Sydney, where Woronora Heights has significantly less development activity, 88.0% below the regional average per person. This scarcity of new homes typically strengthens demand and prices for existing properties. Nationally, this is also lower, reflecting market maturity and possible development constraints.

Recent development has been entirely comprised of detached dwellings, maintaining Woronora Heights' traditional suburban character with a focus on family homes appealing to those seeking space. Population projections showing stability or decline suggest reduced housing demand pressures in the area, benefiting potential buyers.
