Galston

Galston is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Galston's population, as of November 2025, is estimated at around 3,265 people. This figure reflects an increase of 70 individuals from the 2021 Census total of 3,195 people. The current estimate is derived from AreaSearch's validation of new addresses and their analysis of the latest ERP data release by the ABS in June 2024, which indicated a resident population of 3,262. This increase results in a population density ratio of 138 persons per square kilometer. Overseas migration has been the primary driver of population growth in the area during recent periods.

AreaSearch utilises ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch employs NSW State Government's SA2 level projections released in 2022 using a base year of 2021. Growth rates by age group are applied to all areas for the years 2032 to 2041. Looking ahead, lower quartile growth is anticipated for national areas. Based on aggregated SA2-level projections, Galston's population is expected to grow by 92 persons by the year 2041, reflecting an increase of approximately 1.9% over the 17-year period.

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

Galston has received approximately 11 dwelling approvals annually based on AreaSearch analysis of ABS building approval numbers. Between FY-21 and FY-25, around 57 homes were approved, with an additional 2 approved in FY-26 to date. On average, each new home brings about 0.3 new residents per year over the past five financial years.

This indicates that new construction is meeting or exceeding demand, offering buyers more options and potentially supporting population growth. The average expected construction cost value of new dwellings is $1,045,000, suggesting developers target the premium market segment with higher-end properties. In FY-26, Galston has recorded $3.2 million in commercial development approvals, reflecting its residential character. When compared to Greater Sydney, Galston maintains similar development levels per capita, indicating a balanced market consistent with the broader area.

However, this is below the national average, which may suggest maturity and possible planning constraints. Recent construction in Galston comprises 91.0% detached houses and 9.0% attached dwellings, preserving its traditional low-density character focused on family homes appealing to those seeking space. The estimated population per dwelling approval is 496 people, reflecting its quiet, low-activity development environment. Looking ahead, AreaSearch's latest quarterly estimate projects Galston's population to grow by 62 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing favorable conditions for buyers and potentially supporting growth beyond current population projections.
