Glenbrook

Glenbrook has shown very soft population growth performance across periods assessed by AreaSearch

Based on analysis of ABS population updates for the broader area, as of November 2025, Glenbrook's estimated population is around 5,134. This reflects an increase of 56 people since the 2021 Census, which reported a population of 5,078. The change is inferred from AreaSearch's estimate of 5,128 residents following examination of ABS's latest ERP data release in June 2024 and four additional validated new addresses since the Census date. This level of population equates to approximately 730 persons per square kilometer, which aligns with averages across locations assessed by AreaSearch. Glenbrook's growth rate of 1.1% since the census is within 0.1 percentage points of the SA3 area's rate of 1.2%. The primary driver for this population growth was overseas migration, contributing approximately 53.0% of overall gains during recent periods.

AreaSearch uses 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 utilises NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Looking ahead, national area lower quartile growth is anticipated, with Glenbrook expected to expand by 148 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of approximately 3.0% in total over the 17 years.

The level of residential development activity in Glenbrook is very low in comparison to the average area assessed nationally by AreaSearch

Glenbrook has received approximately 4 dwelling approvals annually based on AreaSearch analysis of ABS building approval data. Over the past five financial years, from FY-21 to FY-25, around 20 homes were approved, with one more in FY-26 thus far.

Despite a decrease in population during this period, new supply has likely kept pace with demand, providing good buying options while construction values averaged $501,000. Compared to Greater Sydney, Glenbrook's construction is significantly lower, at 61.0% below the regional average per person. This limited new construction often reinforces demand and pricing for existing properties. Nationally, Glenbrook's construction levels are also lower, suggesting market maturity and possible development constraints. Recent construction consists of 80.0% standalone homes and 20.0% townhouses or apartments, maintaining the area's low-density nature with detached housing appealing to space-seeking buyers.

The estimated population per dwelling approval is 1283 people, reflecting Glenbrook's quiet and low-activity development environment. According to AreaSearch's latest quarterly estimate, Glenbrook's population is projected to grow by 156 residents by 2041. Building activity appears to be aligning with these growth projections, although buyers may face increased competition as the population expands.
