Greenwich

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

As of May 2026, the estimated population of the suburb of Greenwich is around 5,839. This reflects an increase of 370 people since the 2021 Census, which reported a population of 5,469. The latest resident population estimate by AreaSearch was based on examination of the ERP data release by the ABS in June 2025 and validation of one new address since the Census date. This results in a population density ratio of 3,517 persons per square kilometer, placing Greenwich in the upper quartile relative to national locations assessed by AreaSearch. The suburb's growth rate of 6.8% since the 2021 census exceeded the SA4 region average of 5.9%. Overseas migration contributed approximately 79.0% of overall population gains during recent periods.

AreaSearch projections for Greenwich are based on ABS/Geoscience Australia data released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections released in 2022 with a base year of 2021 for areas not covered by the former. Based on these aggregations, Greenwich is expected to grow by 602 persons to 2041, reflecting a total gain of 10.3% over the 16 years.

Residential development activity is slightly higher than average within Greenwich when compared nationally

Greenwich has seen approximately 60 new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Around 300 homes were approved in the past five financial years, from FY21 to FY25, with one additional approval so far in FY26.

Despite a falling population during this period, development activity has been adequate relative to population changes. The average construction cost value for new homes is $541,000, indicating that developers are targeting the premium market segment with higher-end properties. Compared to Greater Sydney, Greenwich shows 68.0% higher new home approvals per person, offering greater choice for buyers. New building activity consists of 3.0% standalone homes and 97.0% attached dwellings, reflecting a trend towards denser development that appeals to downsizers, investors, and entry-level buyers. This shift represents a considerable change from the current housing mix, which is currently 50.0% houses. Greenwich reflects a developing area with around 34 people per approval.

Population forecasts indicate an increase of 602 residents by 2041 based on the latest AreaSearch quarterly estimate. Given current development patterns, new housing supply should meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
