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

Based on analysis of Australian Bureau of Statistics (ABS) population updates for the broader area, and new addresses validated by AreaSearch since the Census, Glen Alpine's population is estimated at around 4,492 as of Nov 2025. This reflects an increase of 63 people (1.4%) since the 2021 Census, which reported a population of 4,429 people. The change is inferred from the resident population of 4,140, estimated by AreaSearch following examination of the latest Estimated Resident Population data release by the ABS in Jun 2024, and an additional 6 validated new addresses since the Census date. This level of population equates to a density ratio of 838 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. Population growth for the suburb was primarily driven by overseas migration that contributed 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 any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Considering the projected demographic shifts, exceptional growth, placing in the top 10 percent of statistical areas analysed by AreaSearch, is predicted over the period with the suburb expected to grow by 4,397 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 100.6% 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

AreaSearch analysis indicates Glen Alpine experienced approximately 2 dwelling approvals annually. Between financial years FY-21 and FY-25, around 12 homes were approved, with an additional 2 approved in FY-26.

This results in an estimated 11.2 new residents arriving per year per dwelling constructed over the past five financial years. Demand significantly exceeds supply, leading to price growth and increased buyer competition. New dwellings are developed at an average expected construction cost of $417,000, below the regional average, suggesting more affordable housing options for buyers. Compared to Greater Sydney, Glen Alpine has significantly less development activity, 92.0% below the regional average per person. This scarcity typically strengthens 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 67.0% standalone homes and 33.0% medium and high-density housing, with a growing mix of townhouses and apartments providing options across different price points. This shows a considerable change from the current housing mix, which is currently 98.0% houses. The estimated count of 1517 people in the area per dwelling approval reflects its quiet, low activity development environment. Looking ahead, Glen Alpine is expected to grow by 4,518 residents through to 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
