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 Feb 2026, Cecil Hills' population is estimated at around 6858 people. This reflects a decrease from the 2021 Census figure of 6906 people. The current estimate is based on AreaSearch's validation of new addresses and examination of ABS's ERP data release in Jun 2024, indicating a resident population of 6848 plus three validated new addresses since the Census date. This results in a density ratio of approximately 1102 persons per square kilometer. Population growth was primarily driven by overseas migration contributing about 70% of overall gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area 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. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Based on aggregated SA2-level projections, Cecil Hills is expected to increase by approximately 723 persons to 2041, reflecting a gain of about 10.4% 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 indicates Cecil Hills has seen approximately 4 new homes approved annually. Between FY21 and FY25, around 22 homes were approved, with 1 more approved in FY26 so far. The annual average construction cost value for these homes is $439,000.

In the current financial year, there have been $76,000 worth of commercial approvals registered, reflecting the area's residential nature. Compared to Greater Sydney, Cecil Hills has significantly less development activity. This limited new supply generally supports stronger demand and values for established properties. However, building activity has accelerated in recent years, reaching a level below 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 1245 people per dwelling approval, demonstrating an established market. Future projections show Cecil Hills adding 713 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.
