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

Based on AreaSearch's analysis, Cecil Hills's population is around 6,858 as of Feb 2026. This reflects a decrease of 48 people (0.7%) since the 2021 Census, which reported a population of 6,906 people. The change is inferred from the estimated resident population of 6,848 from the ABS as of June 2024 and an additional 3 validated new addresses since the Census date. This population level equates to a density ratio of 1,828 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Population growth for the area was primarily driven by overseas migration, which contributed approximately 69.7% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Regarding demographic trends, a population increase just below the median of national statistical areas is expected, with the area expected to grow by 724 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 10.4% in total over the 17 years.

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 experienced around 4 dwellings receiving development approval per year, with 22 homes approved over the past 5 financial years (between FY-21 and FY-25) and 1 so far in FY-26. With population declining over recent years, new supply has likely been keeping up with demand, offering good choice to buyers, while new properties are constructed at an average value of $316,000. There have also been $1.5 million in commercial approvals this financial year, suggesting a predominantly residential focus.

Compared to Greater Sydney, Cecil Hills records markedly lower building activity. This limited new supply generally supports stronger demand and values for established dwellings, though development activity has picked up in recent periods. This is also below average nationally, reflecting the area's maturity and pointing to possible planning constraints. New development consists of 67.0% detached houses and 33.0% attached dwellings, with a growing mix of townhouses and apartments providing options across different price points, from family homes to more affordable compact living. 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. At around 1256 people per approval, Cecil Hills shows a mature, established area.

Looking ahead, Cecil Hills is expected to grow by 714 residents through to 2041 (from the latest AreaSearch quarterly estimate). If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.

Cecil Hills has strong levels of nearby infrastructure activity, ranking in the top 30% nationally

The labour market strength in Cecil Hills positions it well ahead of most Australian regions

Cecil Hills possesses a skilled workforce, with manufacturing and industrial sectors strongly represented, an unemployment rate of just 2.1%, and 5.8% in estimated employment growth over the past year. As of December 2025, 4,081 residents are in work while the unemployment rate is 2.1% below Greater Sydney's rate of 4.2%, and workforce participation is fairly standard (72.2% compared to Greater Sydney's 70.2%). Based on Census responses, a high 37.2% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

The dominant employment sectors among residents include health care & social assistance, retail trade, and manufacturing. The area shows particularly strong specialization in manufacturing, with an employment share of 1.8 times the regional level. On the other hand, professional & technical services are under-represented, with only 6.2% of Cecil Hills's workforce compared to 11.5% in Greater Sydney. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, the 12-month period saw employment increasing by 5.8% alongside the labour force increasing by 5.0%, resulting in unemployment falling by 0.8 percentage points. In contrast, Greater Sydney experienced employment growth of 2.2% and labour force growth of 2.3%, with a marginal rise. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Cecil Hills. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Cecil Hills's employment mix suggests local employment should increase by 6.1% over five years and 12.8% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).

Income analysis reveals strong economic positioning, with the area outperforming 60% of locations assessed nationally by AreaSearch

AreaSearch's latest postcode level ATO data for FY-23 reveals that income in the Cecil Hills SA2 is lower than average on a national basis, with the median assessed at $53,573 while the average income stands at $63,423. This contrasts with Greater Sydney's figures of a median income of $60,817 and an average income of $83,003. Based on Wage Price Index growth of 8.86% since FY-23, current estimates would be approximately $58,320 (median) and $69,042 (average) as of September 2025. From the 2021 Census, household incomes rank exceptionally at the 88th percentile ($2,409 weekly), though personal income ranks lower at the 33rd percentile. The data shows the predominant cohort spans 32.3% of locals (2,215 people) in the $1,500 - 2,999 category, consistent with broader trends across the metropolitan region showing 30.9% in the same category. Economic strength emerges through 37.0% of households achieving high weekly earnings exceeding $3,000, supporting elevated consumer spending. Housing accounts for 13.4% of income while strong earnings rank residents within the 89th percentile for disposable income and the area's SEIFA income ranking places it in the 6th decile.
