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 Duffy

Table Chart PROFILE FAQ

Duffy has an estimated 3,514 residents, up from 3,395 at the 2021 Census — a change of 119 people, or 3.5%. Growth has averaged 1.1% a year over five years. That puts 1,255 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 population of Duffy is estimated at 3,514 as of May 2026. This represents a growth of 119 individuals (3.5%) relative to the 2021 Census, which recorded 3,395 residents. This demographic shift is calculated using the June 2025 ABS estimated resident population of 3,514 alongside 10 newly validated addresses registered after the Census. The resulting population density stands at 1,255 persons per square kilometer, outperforming the typical figures recorded across the country. The 3.5% population expansion since the 2021 Census outpaced the broader SA3 region (1.9%), establishing the suburb as a local growth frontrunner.

The primary driver of these gains was overseas migration, which accounted for roughly 62.4% of the population increase over recent times. Projections from the ABS and Geoscience Australia published in 2024 with a 2022 baseline are applied to each SA2 district. In instances where such data is unavailable, or for periods extending past 2032, growth rates by age bracket from the ACT Government's SA2 projections (2022 baseline) are used. Current trends suggest expansion will track in the lowest national quartile, with estimates indicating the locality will add 82 residents by 2041 based on the most recent annual ERP statistics, representing a long-term growth rate of 2.3% over the 16 years.

Residential SupplyHousing Development & Building Approvals in Duffy

Table Chart PROFILE FAQ

28 new dwellings have been approved in Duffy over the past five years, an average of 5 a year. That is 1.7 approvals per 1,000 residents. Approvals are currently running at an annualised 6, 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

Duffy averages approximately 5 residential development approvals per year, with a cumulative total of 28 dwellings approved over the last 5 financial years. In the current financial year of FY-26, 6 approvals have been documented so far. An average of 6.9 additional residents arrived in the area for every new dwelling constructed over the 5 financial years spanning FY-21 to FY-25, showing that demand heavily outstrips new supply, a dynamic that generally drives up property prices and heightens competition among buyers. The average value of these newly constructed properties is $313,000, which is higher than the regional average and points to a focus on higher-quality builds.

Additionally, commercial development remains quiet, with $209,000 in commercial approvals recorded this financial year. Compared to the Australian Capital Territory, Duffy generates roughly 69% of the per capita construction activity, ranking in the 16th percentile of all localities nationally, which reduces buying options and channels demand toward existing housing stock. This volume of building is also below the national benchmark, highlighting the established profile of the suburb and pointing to possible planning constraints. The mix of new construction consists of 50.0% detached houses and 50.0% multi-dwelling options like apartments or townhouses. This shift toward higher-density options offers cheaper entry points and appeals to first-home buyers, investors, and downsizers. It marks a clear departure from the current housing profile, where houses make up 88.0% of properties, signaling a lack of vacant land and a move toward more diverse, affordable housing. With approximately 1014 people for each dwelling approved, Duffy shows the characteristics of a highly established market. Looking forward, the population of Duffy is projected to rise by 82 residents by 2041, based on the latest quarterly calculations from AreaSearch. The current rate of home building is expected to supply enough housing to meet this demand, supporting a balanced market for buyers and potentially allowing growth to outpace current 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 — 10 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (3,395 at the 2021 Census → 3,514 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 (801081092). 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 Duffy 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 Duffy 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 Duffy 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 (May 2026), property sales & rents (Aug 2026), infrastructure projects (May 2026) 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 Jul 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.
