AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data, NSW State Government's SA2 level projections are used, 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. According to these projections, the area's population is expected to decrease by 129 persons by 2041. However, growth in specific age cohorts is anticipated, notably a projected expansion of 143 people in the 75 to 84 age group.

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 over the past five financial years, totalling seven homes. As of 26 June 2021, zero approvals have been recorded in this financial year. The population decline during this period suggests that new supply has likely kept pace with demand, providing good choice for buyers. The average expected construction cost value for new homes is $230,000, which is below regional norms, indicating more affordable housing options.

In the current financial year, $273,000 in commercial development approvals have been recorded, suggesting a predominantly residential focus. Compared to Greater Sydney, 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 below average, reflecting the area's maturity and possible planning 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 indicate stability or decline, which should reduce housing demand pressures, benefiting potential buyers in the area.
