Casula

Population growth drivers in Casula are above average based on AreaSearch's ranking of recent, and medium to long-term trends

Casula's population, as of February 2026, is approximately 17,677. This figure represents an increase of 1,093 people since the 2021 Census, which recorded a population of 16,584. The growth is inferred from ABS estimated resident population data of 16,801 in June 2024 and an additional 189 validated new addresses since the Census date. This results in a population density ratio of approximately 2,500 persons per square kilometer, placing Casula in the upper quartile relative to other locations assessed by AreaSearch. The area's growth rate of 6.6% since the census is within 1.2 percentage points of the state average of 7.8%, indicating strong growth fundamentals. Overseas migration contributed approximately 61.0% of overall population gains during recent periods, driving primary growth in the area.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch uses NSW State Government's SA2 level projections, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for the years 2032 to 2041. Future population trends project an above median growth for Casula, with an expected increase of 2,769 persons by 2041 based on the latest annual ERP population numbers. This reflects a total increase of approximately 10.7% over the 17-year period.

AreaSearch analysis of residential development drivers sees Casula recording a relatively average level of approval activity when compared to local markets analysed countrywide

Casula has averaged approximately 78 new dwelling approvals annually over the past five financial years, totalling 390 homes. As of FY26 so far, 38 approvals have been recorded. On average, 0.5 new residents per year per dwelling constructed have been added between FY21 and FY25. This pace matches or exceeds demand, offering buyers more options while enabling population growth that could surpass current expectations.

The average construction value of new properties is $284,000, below regional norms, reflecting more affordable housing options. In FY26, $16.5 million in commercial approvals have been registered, indicating moderate levels of commercial development. Compared to Greater Sydney, Casula has around two-thirds the rate of new dwelling approvals per person and ranks among the 63rd percentile nationally. Recent construction comprises 47.0% detached houses and 53.0% medium and high-density housing, marking a significant shift from the current 71.0% houses. This trend suggests diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs.

Casula has approximately 240 people per dwelling approval, indicating a low density market. By 2041, Casula is expected to grow by 1,893 residents (AreaSearch quarterly estimate). With current construction levels, housing supply should meet demand adequately, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Casula has seen below average employment performance when compared to national benchmarks

Casula has a skilled workforce with notable representation in essential services sectors. The unemployment rate was 4.1% as of September 2025, with an estimated employment growth of 4.9% over the past year. In September 2025, 8,435 residents were employed, with an unemployment rate matching Greater Sydney's 4.2%.

Workforce participation was lower at 66.0%, compared to Greater Sydney's 70.0%. Census responses indicated that 35.1% of residents worked from home, potentially influenced by Covid-19 lockdowns. Employment is concentrated in health care & social assistance, retail trade, and manufacturing. The area has a particularly high concentration in transport, postal & warehousing, with employment levels at 1.6 times the regional average.

Conversely, professional & technical services show lower representation at 5.7% compared to the regional average of 11.5%. Limited local employment opportunities are suggested by the ratio of working population to resident population. Over a 12-month period ending in September 2025, employment increased by 4.9%, while labour force grew by 4.0%, reducing the unemployment rate by 0.8 percentage points. In comparison, Greater Sydney saw employment grow by 2.1% and labour force expand by 2.4%, with a slight rise in unemployment of 0.2 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project overall growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Casula's employment mix suggests local employment should increase by 6.3% over five years and 13.3% over ten years, though this is a simplified extrapolation for illustrative purposes and does not account for localized population projections.
