Flagstaff Hill

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

Flagstaff Hill's population, as of November 2025, is approximately 11,220. This figure represents an increase of 436 people since the 2021 Census, which reported a population of 10,784. The growth is inferred from the estimated resident population of 11,185 in June 2024 and an additional 35 validated new addresses since the Census date. This results in a population density of 1,150 persons per square kilometer, roughly inline with averages seen across other locations assessed by AreaSearch. Flagstaff Hill's growth rate of 4.0% since the census is within 0.9 percentage points of the SA3 area (4.9%), indicating competitive growth fundamentals. Overseas migration contributed approximately 71.4% 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 by this data and years post-2032, the SA State Government's Regional/LGA projections are adopted, based on 2021 data and adjusted using a method of weighted aggregation from LGA to SA2 levels. Looking ahead, demographic trends suggest a population increase just below the median of national statistical areas by 2041, with Flagstaff Hill expected to grow by 1,314 persons, reflecting an increase of 11.4% in total over the 17 years.

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

Flagstaff Hill has recorded approximately 21 residential properties granted approval annually. Over the past five financial years, from FY-21 to FY-25105 homes were approved, with a further 12 approved in FY-26 so far. On average, over these years, 3.5 new residents are expected for every home built.

This demand significantly outpaces supply, putting upward pressure on prices and increasing competition among buyers. The average construction value of new properties is $391,000. In the current financial year, $2.3 million in commercial development approvals have been recorded, indicating the area's residential nature. Compared to Greater Adelaide, Flagstaff Hill has significantly less development activity, 61.0% below the regional average per person. This constrained new construction typically reinforces demand and pricing for existing dwellings.

This is also below national averages, suggesting maturity in the area and possible planning constraints. Recent development has been entirely comprised of standalone homes, preserving Flagstaff Hill's suburban nature with an emphasis on detached housing attracting space-seeking buyers. The location currently has approximately 777 people per dwelling approval. Population forecasts indicate Flagstaff Hill will gain 1,279 residents by 2041, according to the latest AreaSearch quarterly estimate. If current construction levels persist, housing supply may lag population growth, likely intensifying buyer competition and underpinning price growth.
