Glenbrook

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

Glenbrook's population, as of Nov 2025, is estimated at around 5,124 people. This figure reflects an increase of 46 individuals since the 2021 Census, which reported a population of 5,078. The Glenbrook statistical area (Lv2) had a resident population of 5,116 in Jun 2024, with 4 additional validated addresses recorded since the Census date. This results in a density ratio of approximately 728 persons per square kilometer. The Glenbrook SA2's growth rate of 0.9% since the Census is within 0.7 percentage points of its SA3 area (1.6%). Overseas migration contributed around 53.0% of overall population gains during recent periods.

Population projections indicate lower quartile growth for national areas, with the Glenbrook SA2 expected to expand by 148 persons to reach a total of 5,272 individuals by 2041, reflecting an increase of approximately 3.2% over the 17-year period.

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 decline during this period suggests that 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. This financial year, $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 at 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 166 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.
