Glen Alpine

An assessment of population growth drivers in Glen Alpine reveals an overall ranking slightly below national averages considering recent, and medium term trends

The population of the suburb of Glen Alpine is estimated at around 4,630 as of Feb 2026. This reflects an increase of 201 people since the 2021 Census, which reported a population of 4,429 people. The change is inferred from AreaSearch's estimation of the resident population at 4,456 following examination of the latest ERP data release by the ABS in June 2024 and an additional 6 validated new addresses since the Census date. This level of population equates to a density ratio of 863 persons per square kilometer. The primary driver for this growth was overseas migration contributing approximately 56% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Considering projected demographic shifts, exceptional growth is predicted over this period, with the suburb expected to grow by 4,211 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 87.2% in total over the 17 years.

Residential development activity is lower than average in Glen Alpine according to AreaSearch's national comparison of local real estate markets

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Glen Alpine has experienced around 7 dwellings receiving development approval each year. An estimated 35 homes were approved over the past five financial years, between FY-21 and FY-25, with a further 17 approved so far in FY-26. This results in an average of approximately 4.1 new residents arriving per dwelling constructed annually during this period.

Consequently, demand significantly exceeds new supply, typically leading to price growth and increased buyer competition. The average value of new dwellings developed is $417,000, slightly above the regional average, suggesting a focus on quality developments. Additionally, $349,000 in commercial development approvals have been recorded this financial year, indicating a predominantly residential focus. Compared to Greater Sydney, Glen Alpine has significantly less development activity, 76.0% below the regional average per person. This scarcity of new homes typically strengthens demand and prices for existing properties.

However, development activity has picked up in recent periods. Nationally, this area also reflects below-average development activity, likely due to its maturity and possible planning constraints. New development consists of 86.0% standalone homes and 14.0% medium and high-density housing, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. The estimated count of 455 people in the area per dwelling approval reflects its quiet, low activity development environment. Looking ahead, Glen Alpine is expected to grow by 4,037 residents through to 2041, according to the latest AreaSearch quarterly estimate. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
