Greenwich

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

Greenwich's estimated population is 5,038 as of November 2025, a decrease of 431 people since the 2021 Census. This reflects a resident population of 5,037, estimated by AreaSearch using ABS' ERP data release from June 2024 and three validated new addresses. The population density is 3,034 persons per square kilometer, placing Greenwich in the upper quartile nationally. Overseas migration contributed approximately 79% 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 by this data, released in 2022 with a base year of 2021.

Growth rates by age group are applied to all areas from 2032 to 2041. Greenwich is projected to grow by 781 persons to 2041, reflecting an increase of 26.1% over the 17 years.

Recent residential development output has been above average within Greenwich when compared nationally

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Greenwich has seen around 60 new homes approved each year. Over the past five financial years, between FY-21 and FY-25, approximately 300 homes were approved, with one more approved so far in FY-26.

Despite a fall in population during this period, development activity has been adequate relative to the population change, which could be beneficial for buyers. The average expected construction cost value of new homes is $541,000, indicating that developers are targeting the premium market segment with higher-end properties. Compared to Greater Sydney, Greenwich shows 74.0% higher new home approvals per person, providing greater choice for buyers and suggesting strong developer confidence in the location. Recent construction comprises 3.0% standalone homes and 97.0% medium and high-density housing, offering affordable entry pathways and attracting downsizers, investors, and first-time purchasers. This represents a significant shift from the area's existing housing composition, which is currently 50.0% houses, suggesting decreasing availability of developable sites and reflecting changing lifestyles and demand for more diverse, affordable housing options. Greenwich has around 37 people per dwelling approval, indicating characteristics of a low-density area. According to AreaSearch's latest quarterly estimate, Greenwich is expected to grow by approximately 1,315 residents through to 2041.

Based on current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
