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 is approximately 11,239 as of August 2025. This figure represents a growth of 455 people since the 2021 Census, which reported a population of 10,784. The increase is inferred from an estimated resident population of 11,185 in June 2024 and an additional 67 validated new addresses since the Census date. This results in a population density ratio of 1,152 persons per square kilometer, comparable to averages seen across other locations assessed by AreaSearch. Flagstaff Hill's growth rate of 4.2% since the Census is within 0.6 percentage points of the SA3 area's growth rate of 4.8%, indicating competitive growth fundamentals. Overseas migration contributed approximately 71.4% of overall population gains during recent periods, driving primary population growth in the area.

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 and released in 2023, with adjustments made using weighted aggregation methods from LGA to SA2 levels. Based on demographic trends and latest population numbers, Flagstaff Hill is expected to grow by approximately 1,314 persons by 2041, representing an increase of about 11.2% 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 has granted around 21 residential property approvals annually. Between financial years FY-21 and FY-25105 homes were approved, with an additional 10 approved in FY-26 so far. On average, each home built over these five years accommodates approximately 3.5 new residents per year.

This demand significantly outpaces supply, putting upward pressure on prices and increasing competition among buyers. New properties are constructed at an average expected cost of $391,000. In FY-26, $2.3 million in commercial development approvals have been recorded, indicating the area's primarily 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, reflecting the area's maturity and possible planning constraints.

Recent development has been entirely standalone homes, preserving the suburban nature of the location and attracting space-seeking buyers. There are approximately 777 people per dwelling approval in Flagstaff Hill, indicating an established market. Population forecasts suggest that Flagstaff Hill will gain 1,260 residents by 2041. If current construction levels persist, housing supply may lag population growth, likely intensifying buyer competition and underpinning price growth.
