Statistical Area (SA2) Boundary Analysis

This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.

SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).

Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

DemographicsPopulation Growth in Flagstaff Hill

Table Chart PROFILE FAQ

Flagstaff Hill has an estimated 11,378 residents, up from 10,784 at the 2021 Census — a change of 594 people, or 5.5%. Growth has averaged 0.9% a year over five years. Overseas migration accounts for 78.4% of that increase. That puts 1,167 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.

Detail

According to investigations by AreaSearch, the resident count of Flagstaff Hill stands at approximately 11,378 in May 2026. This indicates a growth of 594 individuals (5.5%) relative to the 2021 Census, which registered 10,784 residents. This adjustment is calculated based on the ABS estimated resident population of 11,370 in June 2025 alongside 36 validated new addresses documented since the Census. Such population numbers translate to a density of 1,167 persons per square kilometer, a figure that aligns closely with standard metrics across surveyed locations. The 5.5% expansion rate of Flagstaff Hill since the census trails the SA3 region (5.8%) by only 0.3 percentage points, indicating stable underlying growth.

The expansion was primarily supported by overseas migration, which represented roughly 78.4% of the total population gains in recent times. Projections developed by the ABS and Geoscience Australia, published in 2024 with a 2022 baseline, are utilized by AreaSearch for each SA2 region. For locations lacking this data or for projections extending past 2032, regional and LGA projections by age bracket from the SA State Government released in 2023 and utilizing 2021 data are applied, using weighted aggregation to scale growth from LGA to SA2 levels. Looking at upcoming demographic changes, the population is projected to expand at a rate slightly below the national median, with expectations of adding 1,197 residents by 2041 compared to the most recent annual ERP statistics, which would represent a 10.4% increase over 16 years.

Residential SupplyHousing Development & Building Approvals in Flagstaff Hill

Table Chart PROFILE FAQ

105 new dwellings have been approved in Flagstaff Hill over the past five years, an average of 21 a year. That is 1.9 approvals per 1,000 residents. Approvals are currently running at an annualised 20, broadly in line with that longer-run average. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

Flagstaff Hill has averaged approximately 21 residential building approvals annually, with a total of 105 homes approved during the past 5 financial years (between FY-21 and FY-25) and 19 registered during FY-26 so far. With an average of 4.8 new residents added for each home constructed over the past 5 financial years (between FY-21 and FY-25), demand is outstripping supply, a trend that generally drives up prices and heightens buyer competition, while new builds average a construction cost of $226,000—below regional averages—representing more affordable choices for buyers. Furthermore, commercial approvals have reached $2.3 million this financial year, reflecting a low level of commercial building activity.

In comparison to Greater Adelaide, the pace of development in Flagstaff Hill is minimal, tracking 61.0% below the regional average per person. This restricted volume of new housing generally supports demand and prices for existing stock. The level of activity also falls below the national average, reflecting the established state of the suburb and implying potential planning constraints. Furthermore, recent construction has consisted entirely of standalone homes, preserving the area's established suburban layout with a focus on spacious family residences. With roughly 786 people per approval, Flagstaff Hill exhibits the characteristics of a mature, built-out area. Projections indicate that Flagstaff Hill will add 1,189 residents by 2041, based on the most recent quarterly estimate from AreaSearch. If building activity remains at its current level, the supply of new housing may not keep pace with population growth, which is likely to increase buyer competition and support price appreciation.

How the numbers are built

Population

The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 36 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (10,784 at the 2021 Census → 11,378 now). Annual growth rates are compound (CAGR), not simple averages.

Age profile

Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to May 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".

Property sales

Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.

Rents

Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.

Development & infrastructure

Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.

Employment & income

Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.

Education, transport & amenities

School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.

Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.

Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (403041077). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the Flagstaff Hill SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this Flagstaff Hill page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Flagstaff Hill data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Jun 2026), property sales & rents (Aug 2026), infrastructure projects (Oct 2025) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to May 2026), age profile (to May 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
