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 of November 2025, is approximately 6,855 people. This figure reflects a decrease of 51 individuals since the 2021 Census, which recorded a population of 6,906. The change is inferred from the estimated resident population of 6,848 in June 2024 and two validated new addresses added post-Census. This results in a 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 recent population gains.

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, released in 2022 with 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. Based on demographic trends and latest annual ERP population numbers, Cecil Hills is expected to grow by 724 persons by 2041, reflecting a total increase 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 has seen approximately four dwellings granted development approval annually. Over the past five financial years, from FY21 to FY25, 22 homes were approved, with one more approved so far in FY26. The population decline in recent years suggests that new supply has kept pace with demand, offering buyers good choice.

New properties are constructed at an average expected construction cost of $316,000. This financial year has seen $1.5 million in commercial approvals, indicating a predominantly residential focus compared to Greater Sydney's higher building activity levels. Cecil Hills' lower development activity generally supports stronger demand and values for established dwellings, though there has been an increase in recent periods. This is 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 catering to different price points. This marks a shift 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, Cecil Hills is projected to grow by 717 residents (according to the latest AreaSearch quarterly estimate). If current development rates continue, housing supply may not keep pace with population growth, potentially increasing buyer competition and supporting stronger price growth.
