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 is estimated at around 17,677 as of Feb 2026. This reflects an increase of 1,093 people since the 2021 Census, which reported a population of 16,584. The change was inferred from AreaSearch's estimate of the resident population at 16,801 following examination of ABS data released in June 2024 and an additional 189 validated new addresses since the Census date. This level of population equates to a density ratio of 2,500 persons per square kilometer, placing Casula in the upper quartile relative to national locations assessed by AreaSearch. Casula's growth rate of 6.6% since the census positions it within 1.2 percentage points of the state (7.8%), demonstrating competitive growth fundamentals. Overseas migration contributed approximately 61.0% of overall population gains during recent periods in the suburb of Casula.

AreaSearch is adopting 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 utilises 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 years 2032 to 2041. Future population dynamics anticipate an above median growth, with the suburb expected to expand by 2,776 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 10.8% in total over the 17 years.

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

AreaSearch analysis indicates Casula approved around 78 new homes annually. Between FY-21 and FY-25, approximately 390 homes were approved, with 44 more in FY-26 so far. Over the past five financial years, about 0.5 new residents arrived per new home annually.

This suggests new construction is meeting or exceeding demand, offering buyers more options while facilitating population growth. The average dwelling value was $432,000 during this period. In FY-26, Casula has seen $16.5 million in commercial approvals, indicating moderate commercial development levels. Compared to Greater Sydney, Casula shows 62% of construction activity per person and ranks at the 63rd percentile nationally for assessed areas. Recent construction comprises 48.0% detached houses and 52.0% medium and high-density housing.

This shift from the current housing mix (71.0% houses) reflects reduced development site availability and addresses changing lifestyle demands and affordability requirements. Casula has around 228 people per dwelling approval, indicating low density characteristics. By 2041, AreaSearch projects Casula to add approximately 1,900 residents. Current development patterns suggest new housing supply should readily meet demand, providing good conditions for buyers and potentially facilitating population growth beyond current projections.
