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, as per AreaSearch's analysis, stands at approximately 6,841 as of May 2026. This figure represents a decrease from the 2021 Census count of 6,906 people, a difference of 65 individuals (a decline of 0.9%). The population estimate for June 2025 was 6,831, with an additional 3 validated new addresses since the Census date contributing to this change. This results in a population density ratio of 1,824 persons per square kilometer, exceeding the national average assessed by AreaSearch. Overseas migration drove recent population growth, accounting for approximately 70.9% of overall gains.

AreaSearch employs 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 utilized. Growth rates by age group from these aggregations are applied to all areas for the years 2032 to 2041. Looking ahead, demographic trends suggest a population increase slightly below the national median statistical areas' average. By 2041, Cecil Hills is projected to grow by 702 persons based on the latest annual ERP population numbers, marking an overall increase of 10.1% over the 16-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 seen approximately four dwellings receive development approval annually. Between the financial years 2021 (FY-21) and 2025 (FY-25), 22 homes were approved, with an additional four approved in FY-26 to date. The population has been declining recently, suggesting that new supply is likely meeting demand, providing good options for buyers.

New properties are constructed at an average expected cost of $316,000. In FY-26, there have also been $1.5 million in commercial approvals. Compared to Greater Sydney, Cecil Hills has notably lower building activity, which generally supports stronger demand and values for established dwellings. However, development activity has increased recently. Nationally, this is below average, indicating the area's maturity and possible planning constraints. New developments consist of 67.0% detached houses and 33.0% attached dwellings, marking a shift from the current pattern of 95.0% houses.

This change may be due to diminishing developable land availability and evolving lifestyle preferences. Cecil Hills has around 1256 people per approval, indicating a mature, established area. By 2041, it is projected to grow by 692 residents. If current development rates continue, housing supply might not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.

National employment forecasts from Jobs and Skills Australia project national employment growth at 6.6% over five years and 13.7% over ten years.
