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

Cecil Hills' population is approximately 6,858 as of February 2026. This figure represents a decrease of 48 people since the 2021 Census, which reported a population of 6,906. The change was inferred from the estimated resident population of 6,848 in June 2024 and an additional 3 validated new addresses since the Census date. This results in a population density ratio of 1,828 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. Overseas migration contributed approximately 69.7% of overall population gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered, NSW State Government's SA2 level projections are used, 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 demographic trends and the latest annual ERP population numbers, Cecil Hills is expected to grow by approximately 724 persons to 2041, reflecting a total increase of 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

Cecil Hills has averaged approximately four dwelling approvals per year. Between the financial years 2021 and 2025, 22 homes were approved, with one more approved in 2026 to date. The population has been declining recently, suggesting that new supply has been meeting demand, providing good options for buyers.

The average construction cost value of new properties is $316,000. This financial year has seen $1.5 million in commercial approvals, indicating a primarily residential focus. Compared to Greater Sydney, Cecil Hills has lower building activity. This limited supply generally supports stronger demand and values for established dwellings, although development activity has increased recently. This is also below the national average, reflecting the area's maturity and possible planning constraints. New developments consist of 67% detached houses and 33% attached dwellings, with a growing mix of townhouses and apartments offering options across different price points.

This marks a significant change from the current housing pattern, which is 95% houses, suggesting diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. Cecil Hills has around 1256 people per approval, indicating a mature, established area. By 2041, it is projected to grow by 714 residents. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
