Cecil Hills

Cecil Hills is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of May 2026, the estimated population of Cecil Hills is around 6,841, a decrease of 65 people from the 2021 Census figure of 6,906. This decrease was inferred from AreaSearch's estimation of the resident population at 6,831 based on their examination of ABS's ERP data release in June 2025 and validation of three new addresses since the Census date. The population density stands at 1,099 persons per square kilometer. Overseas migration contributed approximately 70% to recent population gains. AreaSearch uses ABS/Geoscience Australia projections for SA2 areas released in 2024 with a base year of 2022 and NSW State Government's SA2-level projections for areas not covered by this data, released in 2022 with a base year of 2021.

These projections indicate that Cecil Hills is expected to increase its population by 701 persons by 2041, reflecting a gain of approximately 10.1% over the 16-year period.

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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Cecil Hills has seen around 4 new homes approved annually. Approximately 22 homes were approved between financial years FY-21 and FY-25, with an additional 4 approved so far in FY-26. The area's population decline suggests that new supply has likely been keeping up with demand, offering good choice to buyers.

New homes are being built at an average expected construction cost value of $439,000, which is somewhat higher than regional norms, reflecting quality-focused development. This financial year, $76,000 in commercial approvals have been registered, demonstrating the area's residential nature. Compared to Greater Sydney, Cecil Hills has significantly less development activity, with limited new supply generally supporting stronger demand and values for established properties. However, building activity has accelerated in recent years, though it remains under the national average, indicating the area's established nature and suggesting potential planning limitations. New building activity shows 75.0% detached dwellings and 25.0% medium and high-density housing, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. This marks a significant departure from existing housing patterns (currently 95.0% houses), suggesting diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs.

The location has approximately 1246 people per dwelling approval, demonstrating an established market. Future projections show Cecil Hills adding 691 residents by 2041, based on the latest AreaSearch quarterly estimate. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
