Cecil Hills
Statistical Area - sa2

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

Cecil Hills's population is approximately 6,855 as of Aug 2025, a decrease of 51 people (0.7%) since the 2021 Census which recorded 6,906 residents. This change is inferred from ABS' estimated resident population of 6,848 in June 2024 and two validated new addresses post-Census date. The population density stands at 1,828 persons per square kilometer, exceeding the national average according to AreaSearch's assessments. Overseas migration contributed about 69.7% of recent population gains. AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022.

For uncovered areas, NSW State Government's SA2 level projections from 2022 with a base year of 2021 are employed. Age group growth rates are applied to all areas from 2032 to 2041. By 2041, Cecil Hills is projected to increase by 724 persons, marking a 10.5% total gain over the 17-year period.

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

Cecil Hills has averaged approximately four new dwelling approvals annually. Development approval data is produced by the Australian Bureau of Statistics on a financial year basis, with 22 homes approved over the past five financial years from FY-21 to FY-25. As of FY-26, there has been one approval so far. The area's population decline has led to adequate development activity relative to other areas, which is beneficial for buyers.

New homes are being constructed at an average expected cost of $439,000, aligning with regional trends. This financial year has seen $1.5 million in commercial approvals, indicating a predominantly residential focus compared to Greater Sydney. Cecil Hills has significantly less development activity than Greater Sydney, which typically reinforces demand and pricing for existing homes due to limited new construction. However, building activity has increased recently. Nationally, development activity is higher, reflecting market maturity and possible development constraints in Cecil Hills. New building activity consists of 67.0% detached dwellings and 33.0% townhouses or apartments, indicating a shift from the area's existing housing composition of 95.0% houses.

This suggests decreasing availability of developable sites and reflects changing lifestyles requiring more diverse, affordable housing options. With approximately 1256 people per dwelling approval, Cecil Hills is considered a highly mature market. Population forecasts indicate an increase of 717 residents by 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.
