Greenwich

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

The population of Greenwich is estimated at 5,038 as of Feb 2026, a decrease of 431 people since the 2021 Census which reported a population of 5,469. This estimation is based on AreaSearch's validation of new addresses following examination of ABS's ERP data release in June 2024 and an additional validated new address since the Census date. The suburb's population density is 3,034 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Overseas migration contributed approximately 79% of overall population gains during recent periods. AreaSearch projects future growth using 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.

These projections indicate an above median population growth is expected for the suburb, with a projected increase of 744 persons to 2041, reflecting a gain of 14.8% over the 17 years.

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

AreaSearch analysis of ABS building approval numbers allocated from statistical area data indicates around 60 new homes approved annually in Greenwich. Approximately 300 homes have been approved over the past five financial years, from FY21 to FY25, with one already approved in FY26.

Despite population decline during this period, development activity has been relatively adequate, which is positive for buyers. The average construction value of new homes is $541,000, suggesting developers target the premium market segment with higher-end properties. Compared to Greater Sydney, Greenwich shows 80.0% 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 composition (currently 50.0% houses) suggests decreasing availability of developable sites and reflects changing lifestyles and demand for 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 expected to grow by 743 residents by 2041.

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

Conversely, construction employs just 4.1% of local workers, below Greater Sydney's 8.6%. The area appears to offer limited local employment opportunities, as indicated by the count of Census working population versus resident population. Over a 12-month period ending in December 2025, employment increased by 0.8%, while labour force grew by 1.0%, causing the unemployment rate to rise by 0.2 percentage points. In comparison, Greater Sydney recorded higher employment and labour force growth rates, with unemployment rising marginally. Jobs and Skills Australia's national employment forecasts from May-25 suggest that national employment should expand by 6.6% over five years and 13.7% over ten years. Applying these projections to Greenwich's employment mix indicates that local employment should increase by 7.9% over five years and 15.6% over ten years, though these are simple weighted extrapolations for illustrative purposes and do not account for localised population projections.
