Chiswick

An assessment of population growth drivers in Chiswick reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of November 2025, the estimated population of Chiswick is around 2,972 people. This reflects an increase of 63 individuals since the Census in 2021, which reported a population of 2,909 people. The current resident population estimate of 2,956 by AreaSearch, based on ABS's ERP data release from June 2024 and additional validated new addresses, indicates a population density ratio of 5,827 persons per square kilometer, placing the suburb in the top 10% nationally. Overseas migration contributed approximately 75.0% to recent population gains. AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022 and NSW State Government's SA2 level projections for areas not covered, released in 2022 with a base year of 2021.

Applying growth rates from these aggregations to all areas until 2041 suggests lower quartile growth for Australian statistical areas. Chiswick is projected to increase by 47 persons to the year 2041, reflecting an overall increase of approximately 0.7% over the 17-year period.

The level of residential development activity in Chiswick is very low in comparison to the average area assessed nationally by AreaSearch

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Chiswick has averaged around 10 new dwelling approvals per year. Over the past five financial years, from FY-21 to FY-25, an estimated 51 homes were approved, with a further 78 approved so far in FY-26.

With population declining over recent years, new supply has likely kept up with demand, offering good choice to buyers. The average expected construction cost value of new homes is $913,000, indicating developers are focusing on the premium market with high-end developments. Compared to Greater Sydney, Chiswick has approximately half the rate of new dwelling approvals per person and ranks among the 33rd percentile nationally, suggesting somewhat limited buyer options while strengthening demand for established properties. Recent construction comprises 38.0% standalone homes and 62.0% townhouses or apartments, promoting higher-density living that creates more affordable entry points for downsizers, investors, and first-home buyers. Interestingly, developers are building more traditional houses than the current mix suggests (17.0% at Census), indicating strong demand for family homes despite density pressures.

Chiswick has approximately 489 people per dwelling approval, reflecting an established area. According to AreaSearch's latest quarterly estimate, Chiswick is expected to grow by 22 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
