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 11,380 residents, up from 10,784 at the 2021 Census — a change of 596 people, or 5.5%. Growth has averaged 0.9% a year over five years. 150 new addresses have been validated here since Census night. 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 research conducted by AreaSearch, the population residing in Flagstaff Hill stands at approximately 11,380 as of Aug 2026. Compared to the 10,784 people counted during the 2021 Census, this indicates an expansion of 596 people (5.5%). This calculation incorporates the ABS estimated resident population figure of 11,370 recorded as of June 2025 alongside 150 validated new addresses identified following the Census. The local density works out to 1,167 persons per square kilometer, aligning closely with broader regional norms evaluated by AreaSearch. Furthermore, the 5.5% post-census rise tracks closely with the broader SA3 area (6.0%), trailing it by only 0.5 percentage points to reflect resilient demographic foundations.

Inbound overseas migration served as the primary growth catalyst, generating roughly 78.4% of total population additions over recent intervals. Projections published by the ABS and Geoscience Australia in 2024, utilising 2022 as their starting baseline, form the foundation of AreaSearch's SA2 modeling. For timeframes extending beyond 2032 or locations absent from that dataset, 2023 SA State Government Regional/LGA age-cohort forecasts based on 2021 numbers are incorporated through a weighted aggregation conversion from LGA to SA2 geographies. Looking ahead, population growth is projected to track marginally beneath the national statistical area median, expanding by 1,189 persons by 2041 according to current annual ERP benchmarks, which translates to an overall 16-year increase of 10.4%.

Residential SupplyHousing Development & Building Approvals in Flagstaff Hill

Table Chart PROFILE FAQ

88 new dwellings have been approved in Flagstaff Hill over the past five years, an average of 17 a year. That is 1.6 approvals per 1,000 residents. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

Residential planning approvals across Flagstaff Hill have averaged roughly 17 dwellings annually, reaching a cumulative 88 homes approved across the past 5 financial years (between FY-22 and FY-26). In that same span (between FY-22 and FY-26), the region gained an average of 5.7 people per year for every home constructed, underscoring a notable shortfall in residential additions relative to population inflow that creates competitive conditions for purchasers and puts upward pressure on values, while newly built residences show an average construction cost of $380,000. Additionally, commercial building approvals have totaled $2.3 million this financial year, reinforcing the district's predominantly residential character.

Building volume in Flagstaff Hill tracks substantially below regional benchmarks, registering 68.0% below the per-capita rate of Greater Adelaide. Such limited construction often supports property values and heightens demand across existing housing stock. Output also trails national averages, an outcome typical of an established community that may also indicate local planning restrictions. Recent residential building activity has been heavily weighted toward detached houses at 88.0%, with medium and high-density housing accounting for the remaining 12.0%, preserving the traditional suburban landscape tailored to families seeking larger footprints. With approximately 597 people per approved dwelling, the suburb displays the characteristics of a fully established market. Based on the most recent quarterly estimate from AreaSearch, Flagstaff Hill is forecast to gain 1,179 residents by 2041. If local building volumes continue at their present pace, new dwelling construction may fall short of demographic expansion, likely driving stronger buyer competition and reinforcing upward momentum in real estate values.

Is the Flagstaff Hill SA2 keeping up with housing demand?
With the population expected to increase by 1,179 people by 2041, around 590 new dwellings will be necessary. Recent approval levels may be insufficient to meet these forecasts, considering the census average of 2.0 persons per dwelling. This indicates potential housing shortages if current approval trends continue.

Jobs & IndustryEmployment Trends in Flagstaff Hill

Table Chart PROFILE FAQ

6,623 residents of Flagstaff Hill are employed, from a labour force of 6,733. Unemployment sits at 1.6%, with participation at 71.2%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.8% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 8,700, about 76% of the resident population, so more people leave the area for work than travel in. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.

Detail

The local labour market in Flagstaff Hill features a highly skilled workforce with substantial participation in core service sectors, an unemployment rate of merely 1.6%, and an estimated job growth rate of 5.2% over the previous year. As of March 2026, 6,623 residents are actively employed, while the local jobless rate sits 2.2% below the Greater Adelaide benchmark of 3.8%. Meanwhile, the local labour force participation rate reaches 71.2%, exceeding Greater Adelaide's 66.4%. In addition, Census records show that a modest 12.3% of workers carried out their duties from home, though this figure was likely shaped by Covid-19 restrictions at the time.

The primary employment fields for local residents comprise health care & social assistance, education & training, alongside retail trade. Concentration is particularly pronounced in education & training, where local employment rates reach 1.3 times the regional standard. Conversely, industrial manufacturing accounts for a comparatively small share of jobs at 5.8%, trailing the regional proportion of 7.0%. Comparing the resident workforce against the number of people working locally during the Census highlights that this primarily suburban setting provides relatively few employment opportunities within its own boundaries. AreaSearch evaluated SALM and ABS statistics for the period ending March 2026, revealing that employment rose by 5.2% while the labour force grew by 5.1%, with unemployment staying largely the same. In contrast, Greater Adelaide experienced a 4.2% rise in employment, a 4.0% expansion in the labour force, and a 0.2 percentage point decline in unemployment. Jobs and Skills Australia provides national employment forecasts from Mar-26 that can illuminate future demand in Flagstaff Hill. These forecasts span five and ten year horizons and have been overlaid onto the local employment profile to project growth trends. Nationally, employment is projected to grow by 6.6% over five years and 13.7% over ten years, though sectoral growth varies considerably. When these industry-specific rates are applied to Flagstaff Hill’s employment composition, local employment is expected to rise by 6.8% over five years and 14.1% over ten years, though this simple weighting exercise is illustrative and does not incorporate localized population projections.

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 — 150 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (10,784 at the 2021 Census → 11,380 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 Aug 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 (Aug 2026), property sales & rents (Sep 2026), infrastructure projects (Oct 2025) and services & amenities (Sep 2026). Built on a Census baseline but carrying newer measures on top: population (to Aug 2026), age profile (to Aug 2026), employment (to Mar 2026), income (to FY 2023), education (to Sep 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.
