Greenfield Park

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

As of November 2025, Greenfield Park's population is estimated at approximately 5,390 people. This figure reflects a decrease of 4 individuals since the 2021 Census, which recorded a population of 5,394. The current estimate is based on AreaSearch's validation of new addresses and analysis of ABS ERP data released in June 2024, indicating a resident population of 5,388. This results in a population density ratio of 3,522 persons per square kilometer, placing Greenfield Park in the upper quartile compared to national locations assessed by AreaSearch. While Greenfield Park experienced a 0.1% decline since the Census, the broader SA3 area achieved 2.2% growth, indicating divergent trends within the region. Overseas migration contributed approximately 76.0% of overall population gains in recent periods.

AreaSearch's projections for each SA2 area are based on ABS/Geoscience Australia data released in 2024 with a 2022 base year. For areas not covered by this data, NSW State Government's SA2-level projections from 2022 with a 2021 base year are used. Growth rates by age group are applied to all areas for the years 2032 to 2041. According to these projections, Greenfield Park is anticipated to experience lower quartile growth, increasing by approximately 29 persons to reach around 5,419 by 2041, reflecting an overall decrease of about 0.7% over the 17-year period.

AreaSearch assessment of residential development drivers sees a low level of activity in Greenfield Park, placing the area among the bottom 25% of areas assessed nationally

Greenfield Park has recorded approximately 16 residential properties granted approval annually based on AreaSearch analysis of ABS building approval numbers. Over the past five financial years, from FY21 to FY25, around 82 homes were approved, with an additional 10 approved so far in FY26. Despite a population decline during this period, housing supply has remained adequate relative to demand, resulting in a balanced market with good buyer choice.

The average value of new homes being built is $254,000, which is below the regional average, suggesting more affordable housing options for buyers. This financial year alone, $9.3 million in commercial development approvals have been recorded, indicating balanced commercial development activity. In comparison to Greater Sydney, Greenfield Park records approximately 66% of the building activity per person and ranks among the 55th percentile of areas assessed nationally, reflecting market maturity and possible development constraints. New developments consist primarily of detached dwellings (94.0%) with a smaller proportion of attached dwellings (6.0%), maintaining the area's traditional suburban character focused on family homes.

With around 288 people per dwelling approval, Greenfield Park exhibits characteristics of a low-density area. Population projections indicate stability or decline in Greenfield Park, which should result in reduced housing demand pressures and benefit potential buyers.
