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

Based on analysis of ABS population updates for Cecil Hills, as of Nov 2025 its estimated population is around 6,855. This reflects a decrease since the 2021 Census, which reported a population of 6,906 people. The change is inferred from AreaSearch's validation of new addresses using ABS ERP data released in June 2024 and an additional two validated new addresses since the Census date. This level of population equates to a density ratio of 1,102 persons per square kilometer. Population growth was primarily driven by overseas migration contributing approximately 70% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for Cecil Hills released in 2024 with a base year of 2022. For areas not covered, NSW State Government's SA2 level projections released in 2022 with a base year of 2021 are used. Considering projected demographic shifts, the suburb is expected to increase by 724 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of approximately 10.5% 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, allocated from statistical area data, indicates Cecil Hills has seen approximately 4 new homes approved annually. Over the past five financial years (between FY21 and FY25), around 22 homes were approved, with 1 more approved so far in FY26. Given population decline in the area, this new supply likely keeps pace with demand, offering buyers good choice.

New homes are being built at an average expected construction cost value of $439,000, aligning with broader regional development. This financial year has seen $76,000 in commercial approvals registered, indicating Cecil Hills' residential nature. Compared to Greater Sydney, Cecil Hills has significantly less development activity, which generally supports stronger demand and values for established properties. However, building activity has accelerated in recent years, though it remains below the national average, suggesting potential planning limitations. New building activity comprises 75.0% detached dwellings and 25.0% medium and 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), potentially indicating diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs.

The location has approximately 1245 people per dwelling approval, demonstrating an established market. Future projections estimate Cecil Hills will add 717 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.
