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

As of Nov 2025, Glen Alpine's population is estimated at around 4,572, reflecting an increase of 143 people since the 2021 Census. This increase represents a growth rate of approximately 3.2%. The change is inferred from AreaSearch's estimation of the resident population as 4,456 in June 2024, based on examination of the latest ERP data release by the ABS, and an additional 6 validated new addresses since the Census date. This level of population results in a density ratio of 853 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. Overseas migration contributed approximately 56% of overall population gains during recent periods, primarily driving growth for the area.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in Jun 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 for Glen Alpine (SA2), placing it in the top 10 percent of statistical areas analysed by AreaSearch. By 2041, the area is expected to grow by approximately 4,398 persons, reflecting a gain of around 97.1% over the 17-year period.

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, Glen Alpine has experienced around 5 dwellings receiving development approval each year. Between FY21 and FY25, approximately 29 homes were approved, with an additional 11 so far in FY26. On average, 4.7 new residents arrive per year per dwelling constructed during this period.

This indicates demand significantly exceeds supply, typically leading to price growth and increased buyer competition. The average construction cost of new dwellings is $417,000, slightly above the regional average. In FY26, commercial development approvals totaled $349,000, suggesting a predominantly residential focus. Compared to Greater Sydney, Glen Alpine has significantly less development activity, 80.0% below the regional average per person. This scarcity of new homes can strengthen demand and prices for existing properties. However, recent periods have seen an increase in development activity.

Nationally, this is also below average, reflecting the area's maturity and possible planning constraints. New development consists of 71.0% standalone homes and 29.0% medium to high-density housing, maintaining Glen Alpine's traditional low density character with a focus on family homes appealing to those seeking space. This shows a considerable change from the current housing mix, which is currently 98.0% houses, reflecting reduced availability of development sites and addressing shifting lifestyle demands and affordability requirements. The estimated count of 569 people in the area per dwelling approval reflects its quiet, low activity development environment. Looking ahead, Glen Alpine is expected to grow by 4,439 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.
