This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
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
As of May 2026, the estimated population of the suburb of Flagstaff Hill is around 10,582. This figure represents an increase of 398 people since the 2021 Census, which reported a population of 10,184. The latest estimate is based on AreaSearch's validation of new addresses and analysis of resident population data from June 2025 ABS ERP release. This results in a population density ratio of 1,346 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. Flagstaff Hill's growth rate of 3.9% since the census is within 1.9 percentage points of the SA3 area's growth rate of 5.8%. Overseas migration contributed approximately 71.0% to overall population gains in recent periods.
AreaSearch uses 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, adjusted using a method of weighted aggregation from LGA to SA2 levels. Future population dynamics anticipate an increase just below the median for national areas. By 2041, the suburb is expected to expand by approximately 1,100 persons, reflecting a total gain of 10.3% over the 16-year period.

Development
Residential development activity is lower than average in Flagstaff Hill according to AreaSearch's national comparison of local real estate markets
Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Flagstaff Hill averaged around 13 new dwelling approvals each year. Between FY21 and FY25, approximately 67 homes were approved, with a further 15 approved in FY26 to date.
This results in an average of 4.8 people moving to the area for each dwelling built over these years. The demand significantly outpaces supply, typically putting upward pressure on prices and increasing competition among buyers. New homes are being built at an average expected construction cost value of $391,000, indicating that developers target the premium market segment with higher-end properties. Compared to Greater Adelaide, Flagstaff Hill records markedly lower building activity, 73.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing dwellings.
Nationally, this is also below average, reflecting the area's maturity and possible planning constraints. Recent development has been entirely comprised of detached dwellings, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space. The location has approximately 1306 people per dwelling approval, demonstrating an established market. Population forecasts indicate Flagstaff Hill will gain 1,092 residents through to 2041 (from the latest AreaSearch quarterly estimate). At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
