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 Feb 2026, the estimated population of the suburb of Greenwich is around 5,038, a decrease of 431 people since the 2021 Census. This reflects a population density ratio of 3,034 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. The change is inferred from resident population data validated by AreaSearch following examination of ERP data released by the ABS in June 2024 and additional new addresses since the Census date. Population growth was primarily driven by overseas migration contributing approximately 79.0% of overall population gains during recent periods. For demographic projections, 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, 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. Based on aggregated SA2-level projections, the suburb of Greenwich is expected to grow by 772 persons to 2041, reflecting a gain of 26.0% in total over the 17-year period.

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

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

Despite population decline during this period, development activity has been adequate relative to population changes, which is positive for buyers. The average expected construction cost value of new homes is $541,000, suggesting developers target the premium market segment with higher-end properties. Compared to Greater Sydney, Greenwich shows 74.0% higher new home approvals per person, offering greater choice for buyers and indicating strong developer confidence in the location. Recent construction comprises 3.0% standalone homes and 97.0% medium and high-density housing, providing affordable entry pathways and attracting downsizers, investors, and first-time purchasers. This shift from the area's existing housing (currently 50.0% houses) reflects decreasing developable sites and changing lifestyles requiring diverse, affordable housing options. With around 37 people per dwelling approval, Greenwich exhibits characteristics of a low-density area. According to AreaSearch's latest quarterly estimate, Greenwich is projected to grow by 1,309 residents by 2041.

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

This contrasts with Greater Sydney where employment grew by 2.1%. Jobs and Skills Australia's national employment forecasts from May-25 suggest potential future demand within Greenwich. These projections estimate national employment growth of 6.6% over five years and 13.7% over ten years. Applying these industry-specific projections to Greenwich's employment mix suggests local employment should increase by 7.9% over five years and 15.6% over ten years, though these are simple weighting extrapolations for illustrative purposes and do not account for localised population projections.
