Detail

According to investigations of ABS demographic statistics for the surrounding region, combined with fresh locations confirmed by AreaSearch after the Census, the resident count for the suburb of Willunga is projected to be approximately 2,594 as of May 2026. This represents an addition of 149 people (6.1%) from the 2021 Census, which documented a total of 2,445 people. The adjustment is calculated from a resident base of 2,591, determined by AreaSearch through analyzing the most recent June 2025 ERP release from the ABS alongside an extra 44 validated new addresses since the Census date.

This population size corresponds to a density of 122 persons per square kilometer, which offers ample personal space and potential capacity for future growth. The 6.1% growth recorded in the suburb of Willunga since the 2021 census outpaced the SA3 area (5.8%), establishing it as a local growth frontrunner. Growth in the area was chiefly fueled by interstate migration, which accounted for roughly 64.0% of all demographic increases during the recent timeframe, even though all other components including overseas arrivals and natural increase remained positive. AreaSearch utilizes ABS and Geoscience Australia demographic projections for each SA2 region, which were published in 2024 using 2022 as the baseline year. For SA2 territories lacking this coverage, and for any years after 2032, regional and LGA age-group projections published by the SA State Government in 2023 (based on 2021 statistics) are applied, utilizing a weighted aggregation method to translate growth from LGA to SA2 levels. Regarding future demographic trends, expansion is projected to run just under the median of national statistics, with the suburb of Willunga anticipated to add 227 residents by 2041 based on compiled SA2 projections, representing an overall rise of 8.6% across the 16 years.

Furthermore, commercial approvals totaling $232,000 have been logged during the current financial year, highlighting the predominantly residential character of the locality. When compared to Greater Adelaide, Willunga displays a matching volume of construction activity on a per-capita basis, maintaining a balanced market in line with nearby districts.

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 — 44 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (2,445 at the 2021 Census → 2,594 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 (SAL41610). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

How do Willunga suburb boundaries differ from Statistical Areas?
This page uses Suburbs and Localities (SAL) boundaries (suburb-style geography). SAL represents commonly-known suburb names used in addresses, while Statistical Areas (SA2) are designed for census/statistical reporting. Even when sharing the same name, SAL and SA2 boundaries often cover different geographic areas with different populations.
Where does the data on this Willunga 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 Willunga 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 (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 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.
