Glenbrook

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

As of Feb 2026, Glenbrook's population is estimated at around 5,127. This reflects an increase of 49 people since the 2021 Census, which reported a population of 5,078. The change was inferred from AreaSearch's estimate of 5,116 residents following examination of ABS ERP data release in June 2024 and one additional validated new address since the Census date. Glenbrook's population density is approximately 729 persons per square kilometer, comparable to averages seen across locations assessed by AreaSearch. The suburb's 1.0% growth since census positions it within 0.7 percentage points of the SA3 area (1.7%), indicating competitive growth fundamentals. Overseas migration contributed approximately 53.0% of overall population gains during recent periods in Glenbrook.

For projections, AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. Lower quartile growth is anticipated moving forward, with the suburb expected to expand by 147 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 3.1% 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

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, Glenbrook has experienced around 4 dwellings receiving development approval each year. Approximately 20 homes have been approved over the past five financial years, between FY-21 and FY-25, with 1 so far in FY-26. The population has fallen during this period, suggesting new supply has likely kept up with demand, offering good choice to buyers.

New properties are constructed at an average expected construction cost value of $501,000, indicating a developer focus on the premium segment with upmarket properties. In FY-26, $4.8 million in commercial development approvals have been recorded, suggesting limited commercial development focus. Compared to Greater Sydney, Glenbrook records markedly lower building activity, 61.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing dwellings, which is also under the national average, indicating the area's established nature and suggesting potential planning limitations. Recent construction comprises 80.0% detached dwellings and 20.0% townhouses or apartments, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space.

The estimated count of 1283 people in the area per dwelling approval reflects its quiet, low activity development environment. Future projections show Glenbrook adding 160 residents by 2041, from the latest AreaSearch quarterly estimate. Development is keeping reasonable pace with projected growth, though buyers may face increasing competition as the population expands.

Census responses indicate that 50.0% of residents work from home, though Covid-19 lockdown impacts should be considered.

Between September 2024 and September 2025, Glenbrook's labour force decreased by 4.3%, while employment declined by 4.2%, resulting in a fall of 0.2 percentage points in the unemployment rate. This contrasts with Greater Sydney where employment rose by 2.1%, the labour force grew by 2.4%, and unemployment rose by 0.2 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 suggest potential future demand within Glenbrook. These projections estimate that national employment will expand by 6.6% over five years and 13.7% over ten years, with growth rates varying significantly between industry sectors. Applying these industry-specific projections to Glenbrook's employment mix suggests local employment should increase by 6.8% over five years and 13.9% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localized population projections.
