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 research conducted by AreaSearch, Duffy records an estimated population of approximately 3,514 as of Aug 2026. This represents an addition of 119 people (3.5%) compared to the 3,395 people documented in the 2021 Census. This adjustment stems from the ABS estimated resident population figure of 3,514 recorded in June 2025 alongside 10 validated new addresses identified following the Census. Consequently, population density stands at 1,255 persons per square kilometer, tracking higher than the nationwide benchmark assessed by AreaSearch. Furthermore, the local expansion rate of 3.5% since the 2021 census outperformed the wider SA3 area (1.9%), establishing Duffy as a regional growth outperformer.

The primary driver of this demographic expansion was net overseas migration, generating roughly 62.4% of total local population additions over recent timeframes. Projections compiled by ABS/Geoscience Australia released in 2024 (anchored to a 2022 baseline) are applied across SA2 territories by AreaSearch. Wherever coverage is absent, or for periods extending post-2032, age-cohort trajectory projections from the ACT Government (also utilizing a 2022 base) are utilized. Anticipated future trends place the suburb in the bottom quartile across Australian statistical divisions, forecasting an overall increment of 81 persons through to 2041 under latest annual ERP figures, which translates to a 2.3% aggregate increase across the 16 years.

Residential SupplyHousing Development & Building Approvals in Duffy

Table Chart PROFILE FAQ

29 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. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

Annual residential approvals in Duffy have averaged roughly 5 new homes, delivering an aggregate of 29 homes over the previous 5 financial years. With an inflow averaging 6.6 new residents per year for each residential unit completed over the preceding 5 financial years (covering FY-22 to FY-26), additions to local housing stock are trailing population demand significantly, generating intensified competition among purchasers and subsequent upward price pressure, alongside an average construction cost of $361,000 per dwelling. Furthermore, the district registered $209,000 in approved commercial works during the current financial year, underlining its deeply residential character.

Residential building output across Duffy lags substantially behind wider territory activity, sitting 56.0% below regional average per person seen throughout Australian Capital Territory. Such constrained construction tends to reinforce pricing and buyer interest across established dwellings. Development levels are also subdued relative to national benchmarks, highlighting local market maturity along with potential physical or regulatory land constraints. Of recent building approvals, standalone houses represent 40.0% while attached residences account for 60.0%. This shift toward medium density provides accessible price points that appeal to downsizers, property investors, and first-home purchasers. This composition represents a clear transition from the prevailing built environment (where separate houses constitute 88.0%), reflecting both limited vacant sites and shifting demographic preferences for manageable, affordable housing options. With approximately 864 people per approval, Duffy typifies a well-settled, mature urban fabric. According to the latest quarterly estimates from AreaSearch, Duffy is projected to add 81 residents by 2041. Under current construction trajectories, incoming residential developments are well positioned to satisfy anticipated demand, creating favorable buyer conditions and potentially supporting demographic expansion above existing baseline forecasts.

Leading fields of employment for local workers include public administration & safety, professional & technical, and health care & social assistance.

In contrast, the accommodation & food sector accounts for a smaller footprint at 5.0%, trailing the broader regional baseline of 6.5%.

Across Australian Capital Territory over the same timeframe, employment climbed 0.3%, the labor force widened by 1.1%, and joblessness rose 0.7 percentage points. Projections published by Jobs and Skills Australia as of Mar-26 provide an outlook on future employment requirements across the area. When projected across Duffy's specific occupational makeup over five- and ten-year intervals, national projections anticipate broad job gains of 6.6% over five years and 13.7% over ten years, albeit with notable sectoral divergence. Weighting these projections to the suburb's workforce structure indicates an expected local employment expansion of 6.5% over five years and 13.2% over ten years (calculated strictly as an illustrative baseline weighting without incorporating localized demographic shifts).

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 Aug 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 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 (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 (Aug 2026), property sales & rents (Sep 2026), infrastructure projects (May 2026) and services & amenities (Jul 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 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.
