Flagstaff Hill

Flagstaff Hill is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Flagstaff Hill's population, as of November 2025, is estimated at approximately 10,523 people. This figure represents an increase of 339 individuals since the 2021 Census, which recorded a population of 10,184 in Flagstaff Hill statistical area (Lv2). The change was inferred from AreaSearch's estimation of the resident population at 10,480 following examination of the ABS's latest ERP data release in June 2024 and an additional 14 validated new addresses since the Census date. This results in a density ratio of 1,338 persons per square kilometer for Flagstaff Hill (SA2), which is higher than the average seen across national locations assessed by AreaSearch. The area's population growth rate of 3.3% since the census places it within 2.9 percentage points of the SA3 area's growth rate of 6.2%, indicating competitive growth fundamentals. Overseas migration contributed approximately 71.0% of overall population gains during recent periods in Flagstaff Hill (SA2).

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 by age category are adopted, based on 2021 data released in 2023, with adjustments made using a method of weighted aggregation of population growth from LGA to SA2 levels. Future population dynamics anticipate a growth rate just below the median of national areas, with Flagstaff Hill (SA2) expected to expand by approximately 1,209 persons to reach a total population of around 11,732 by 2041, reflecting a gain of 10.8% over the 17-year period.

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

Flagstaff Hill averaged approximately 13 new dwelling approvals annually based on AreaSearch analysis of ABS building approval numbers. Between financial years FY-21 and FY-25, around 67 homes were approved, with a further 13 approved in FY-26.

This results in an average of 5.3 people moving to the area per dwelling built over these five years. The demand for housing significantly outpaces supply, which typically influences prices upwards and intensifies competition among buyers. Developers target the premium market segment, with new homes constructed at an average value of $391,000. Compared to Greater Adelaide, Flagstaff Hill has markedly lower building activity, recording 73.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing dwellings.

Recent development has been exclusively detached dwellings, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space. The location has approximately 1304 people per dwelling approval, indicating an established market. Population forecasts suggest Flagstaff Hill will gain 1,140 residents by 2041. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.

Greater Adelaide recorded employment growth of 3.0%, labour force growth of 2.9%, and a fall in unemployment of 0.1 percentage points during the same period.

National unemployment is 4.3%, but SA's employment growth outpaces the national average of 0.14%. Jobs and Skills Australia forecasts suggest national employment will expand by 6.6% over five years and 13.7% over ten years, with varying growth rates between industry sectors. Applying these projections to Flagstaff Hill's employment mix indicates local employment should increase by 6.8% over five years and 14.2% over ten years (simple weighting extrapolation for illustrative purposes).
