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

The population of the Cecil Hills statistical area (Lv2) is estimated at approximately 6,855 as of November 2025. This figure reflects a decrease of 51 people since the 2021 Census, which reported a population of 6,906. The change is inferred from AreaSearch's estimation of the resident population at 6,848 in June 2024, considering the latest ERP data release by the ABS and two validated new addresses since the Census date. This results in a density ratio of 1,102 persons per square kilometer, which aligns with averages seen across locations assessed by AreaSearch. Overseas migration contributed approximately 70% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections 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. Considering projected demographic shifts, the Cecil Hills (SA2) is expected to increase its population by just below the median of national statistical areas, reaching an estimated total of 7,579 persons by 2041. This reflects a gain of approximately 10.5% 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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Cecil Hills has seen approximately 4 new homes approved annually. Between FY-21 and FY-25, around 22 homes were approved, with 1 so far in FY-26. This level is significantly less than Greater Sydney's activity.

The area has experienced population decline, suggesting demand for new supply has been met by development. New homes are being built at an average value of $439,000, reflecting quality-focused development. In FY-26, $76,000 in commercial approvals have been registered, indicating the area's residential nature. Measured against national averages, Cecil Hills has lower development activity, suggesting established planning limitations and supporting stronger demand for established properties. New building activity comprises 75.0% detached dwellings and 25.0% medium to high-density housing, maintaining the area's suburban character focused on family homes. This marks a shift from existing housing patterns (currently 95.0% houses), potentially due to diminishing developable land availability and evolving lifestyle preferences.

The location has approximately 1245 people per dwelling approval, indicating an established market. Future projections estimate Cecil Hills will add 717 residents by 2041, suggesting current development rates may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
