Glenalta

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

Based on ABS population updates and AreaSearch's validation of new addresses, Glenalta statistical area (Lv2)'s population was estimated at 2,130 as of Nov 2025. This reflects an increase of 91 people since the 2021 Census, which reported a population of 2,039 people. The change is inferred from AreaSearch's estimate of 2,120 residents following examination of ABS's latest ERP data release (June 2024) and address validation since the Census date. This level of population equates to a density ratio of 1,789 persons per square kilometer. Over the past decade, Glenalta demonstrated resilient growth patterns with a compound annual growth rate of 1.4%, outpacing the SA3 area. Population growth was primarily driven by overseas migration contributing approximately 55% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, SA State Government's Regional/LGA projections by age category are adopted, adjusted using a method of weighted aggregation from LGA to SA2 levels. Based on aggregated SA2-level projections, Glenalta (SA2) is expected to increase by 282 persons to reach 2,412 by 2041, reflecting an overall increase of 15% over the 17 years.

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

Based on AreaSearch analysis of ABS building approval numbers, Glenalta has experienced around 2 dwellings receiving development approval per year over the past 5 financial years from FY-21 to FY-25. This totals an estimated 14 homes. So far in FY-26, 0 approvals have been recorded.

On average, 12.1 people have moved to the area annually for each dwelling built during these years. Supply is substantially lagging demand, which generally means heightened buyer competition and pricing pressures. New homes are being built at an average expected construction cost of $557,000, indicating a developer focus on the premium segment with upmarket properties. Relative to Greater Adelaide, Glenalta shows reduced construction activity, with 61.0% fewer approvals per person. This scarcity typically strengthens demand and prices for existing properties.

Building activity has accelerated in recent years but remains lower than nationally, reflecting market maturity and possible development constraints. Recent building activity consists entirely of standalone homes, preserving the area's suburban nature and attracting space-seeking buyers. Glenalta shows a mature, established area with around 614 people per approval. Future projections show Glenalta adding 319 residents by 2041 from the latest AreaSearch quarterly estimate. If current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.
