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

By Nov 2025, Galston's population is estimated at around 3,270 based on ABS updates and AreaSearch validation. This reflects a growth of 75 people since the 2021 Census, which recorded 3,195 residents. The increase is inferred from an estimated resident population of 3,268 by AreaSearch following the latest ERP data release by the ABS (June 2024) and 43 new addresses validated since the Census date. This results in a density ratio of 138 persons per square kilometer. Galston's growth rate of 2.3% since census is within 0.9 percentage points of its SA3 area, indicating competitive growth fundamentals. Overseas migration primarily drove this population growth.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area (released in 2024 with a 2022 base year) and NSW State Government's SA2-level projections for areas not covered by this data (released in 2022 with a 2021 base year). Growth rates by age group are applied to all areas from 2032 to 2041. By 2041, Galston is projected to grow by 94 persons based on aggregated SA2-level projections, reflecting an increase of 1.8% over the 17 years.

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 averaged around 8 dwelling approvals per year based on AreaSearch analysis of ABS building approval numbers. Between FY-21 and FY-25, approximately 41 homes were approved, with an additional 2 approved in FY-26. On average, each new home brought in about 0.4 new residents annually over the past five financial years.

This suggests that new construction is keeping pace with demand, offering more housing options while supporting population growth. The average value of new dwellings approved was $1,045,000, indicating a focus on premium market segments. In FY-26, Galston has recorded $4.2 million in commercial development approvals, reflecting its residential character. Compared to Greater Sydney, Galston has about three-quarters the rate of new dwelling approvals per person.

Nationally, it ranks at the 43rd percentile for areas assessed, suggesting limited housing choices and supporting demand for existing homes. Recent construction in Galston comprises 86.0% detached houses and 14.0% attached dwellings, maintaining its traditional low-density character with a focus on family homes. The estimated population per dwelling approval is 379 people, reflecting its quiet development environment. Looking ahead, AreaSearch's latest quarterly estimate projects Galston to grow by 59 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.
