Cecil Hills
Statistical Area - sa2

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 6,855 as of November 2025. This figure reflects a decrease of 51 people since the 2021 Census, which recorded a population of 6,906. The decline is inferred from ABS data estimating the resident population at 6,848 in June 2024 and two additional validated addresses post-Census. This results in a density ratio of 1,828 persons per square kilometer, exceeding national averages according to AreaSearch assessments. Overseas migration accounted for approximately 69.7% of recent population growth in the area.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered by this data, NSW State Government's SA2 level projections from 2022 using a base year of 2021 are applied. Growth rates by age group from these aggregations are used for all areas between 2032 and 2041. Future population trends indicate an expected increase just below the national median, with Cecil Hills projected to expand by 724 persons by 2041 based on current numbers, representing a total gain of 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

Cecil Hills averaged approximately four new dwelling approvals per year over the past five financial years, from FY-21 to FY-25, with a total of 22 homes approved during this period and one so far in FY-26. The population has decreased slightly during this time, yet housing supply has remained adequate relative to demand, resulting in a balanced market with good buyer choice. New properties are constructed at an average expected construction cost value of $316,000.

In the current financial year, $1.5 million worth of commercial approvals have been registered, indicating the area's residential nature. Compared to Greater Sydney, Cecil Hills has significantly less development activity, which typically strengthens demand and prices for existing properties. However, building activity has increased in recent years, reaching 67.0% detached dwellings and 33.0% townhouses or apartments. This shift from the current housing mix of 95.0% houses reflects reduced availability of development sites and addresses changing lifestyle demands and affordability requirements. Cecil Hills has a population density of around 1256 people per dwelling approval, indicating a highly mature market. Population forecasts suggest that Cecil Hills will gain 717 residents by 2041.

At current development rates, housing supply may struggle to keep pace with population growth, potentially intensifying buyer competition and supporting price increases.
