Castle Hill - East
Statistical Area - sa2

Castle Hill - East is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Castle Hill - East's population was 5,383 as of Aug 2025, a decrease of 287 people from the 2021 Census figure of 5,670. The change is inferred from ABS estimated resident population of 5,385 in June 2024 and address validation since the Census date. This results in a population density ratio of 2,600 persons per square kilometer, placing Castle Hill - East in the upper quartile relative to national locations assessed by AreaSearch. Overseas migration primarily drove population growth in recent periods. AreaSearch adopts 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 used. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population dynamics anticipate an increase just below the median of national statistical areas, with Castle Hill - East expected to expand by 510 persons to 2041 based on latest population numbers, recording a gain of 9.5% over the 17 years.

The level of residential development activity in Castle Hill - East is very low in comparison to the average area assessed nationally by AreaSearch

Castle Hill - East has recorded approximately three residential properties granted approval annually. Between FY21 and FY25, 16 homes were approved, with none yet approved in FY26.

The population has declined recently, but housing supply has remained adequate relative to demand, creating a well-balanced market with good buyer choice. New properties are constructed at an average expected cost of $186,000, below regional norms, offering more affordable housing options for purchasers. Compared to Greater Sydney, Castle Hill - East has significantly less development activity, being 94.0% below the regional average per person. This scarcity typically strengthens demand and prices for existing properties, reflecting the area's maturity and possible planning constraints. Recent development has been entirely comprised of detached dwellings, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space.

New construction favours detached housing more than current patterns suggest, indicating ongoing robust demand for family homes. Castle Hill - East shows a mature, established area with around 4040 people per approval. Population forecasts indicate an increase of 511 residents by 2041. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
