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 Cecil Hills is estimated at around 6,858 as of February 2026, based on ABS population updates and new addresses validated by AreaSearch. This reflects a decrease of 48 people since the 2021 Census, which reported a population of 6,906. The current estimate is inferred from the resident population of 6,848 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 3 validated new addresses since the Census date. This level of population equates to a density ratio of 1,102 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. Overseas migration contributed approximately 70.0% of overall population gains during recent periods for the suburb of Cecil Hills.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections, 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. Considering projected demographic shifts, a population increase just below the median of national statistical areas is expected for Cecil Hills. The area is projected to increase by 724 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 10.4% in total over the 17 years.

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 indicates Cecil Hills has seen approximately 4 new homes approved annually. Between Financial Year 21 (FY-21) and FY-25, about 22 homes were approved, with 1 more in FY-26 so far. This suggests new supply is likely keeping pace with demand due to population decline, offering buyers good choice.

New homes are built at an average construction cost value of $439,000, higher than regional norms, reflecting quality-focused development. In FY-26, $76,000 in commercial approvals have been registered, showing the area's residential nature. Comparatively, Cecil Hills has significantly less development activity than Greater Sydney. This limited new supply generally supports stronger demand and values for established properties. However, building activity has accelerated in recent years, though it remains below national averages, indicating the area's established nature and suggesting potential planning limitations. New building activity shows 75.0% detached dwellings and 25.0% medium to high-density housing, maintaining Cecil Hills' traditional suburban character focused on family homes appealing to those seeking space.

This marks a significant shift from existing housing patterns (currently 95.0% houses), suggesting diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. Cecil Hills has approximately 1245 people per dwelling approval, indicating an established market. Future projections show Cecil Hills adding 714 residents by 2041 (from 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.
