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 was around 17,135 as of May 2026. This reflected an increase of 551 people since the 2021 Census, which reported a population of 16,584 people. The change was inferred from the estimated resident population of 17,039 from the ABS in June 2025 and an additional 199 validated new addresses since the Census date. This levelled to a density ratio of 2,423 persons per square kilometer, placing Casula in the upper quartile relative to national locations assessed by AreaSearch. Overseas migration contributed approximately 63.8% of overall population gains during recent periods.

AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered, AreaSearch utilised NSW State Government's SA2 level projections, released in 2022 with a base year of 2021. Growth rates by age group were applied to all areas for years 2032 to 2041. Future population trends projected an above median growth, with Casula expected to increase by 2,657 persons to 2041 based on the latest annual ERP population numbers, reflecting a total increase of 14.9% over the 16 years.

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, 55 approvals have been recorded. On average, 0.5 new residents per year per dwelling constructed were added between FY21 and FY25. The average construction value of new properties was $284,000, below regional norms.

This financial year, Casula has registered $16.5 million in commercial approvals. 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, indicating a shift from existing patterns (currently 71.0% houses). The location has approximately 240 people per dwelling approval, suggesting a low density market. By 2041, Casula is expected to grow by an estimated 2,561 residents.

With current construction levels, housing supply should meet demand adequately, creating favourable conditions for buyers and potentially enabling growth beyond 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 4.2% as of December 2025, aligning with Greater Sydney's rate. Employment growth over the past year was estimated at 5.7%.

As of December 2025, 8,547 residents were employed, with a workforce participation rate of 65.8%, slightly below Greater Sydney's 68.8%. Census responses indicated that 35.1% of residents worked from home. 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%. Employment opportunities locally may be limited, as suggested by the count of Census working population versus resident population. Between December 2024 and November 2025, employment increased by 5.7%, while the labour force grew by 5.0%, causing a decrease in unemployment rate by 0.6 percentage points. In contrast, Greater Sydney saw employment grow by 2.2% over the same period, with a marginal rise in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 project overall employment 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 localised population projections.
