AreaSearch implements ABS/Geoscience Australia projections for each SA2 region, which were published in 2024 using 2022 as the baseline.

Residential SupplyHousing Development & Building Approvals in Noarlunga Downs

Table Chart PROFILE FAQ

39 new dwellings have been approved in Noarlunga Downs over the past five years, an average of 7 a year. That is 1.9 approvals per 1,000 residents. Approvals are currently running at an annualised 10, running ahead of that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.

Detail

Based on AreaSearch's evaluation of ABS building approval statistics compiled from statistical area data, the suburb of Noarlunga Downs has averaged about 7 new residential approvals annually, with an estimated 39 homes approved over the prior 5 financial years (between FY-21 and FY-25) and 10 so far in FY-26. With an average of only 0.6 people per year moving to the area for each dwelling built over the past 5 financial years (between FY-21 and FY-25), housing supply is matching or exceeding demand, offering buyers more choices while supporting the potential for population growth to outpace projections, with new dwellings being constructed at an average value of $280,000.

Additionally, commercial approvals reached $1.3 million this financial year, highlighting the residential character of the locality. Relative to Greater Adelaide, the suburb of Noarlunga Downs displays much lower construction activity (61.0% below the regional average per capita). This constrained new supply generally underpins stronger demand and pricing for existing homes. This rate is also below the national average, reflecting market maturity and indicating potential development constraints. New construction consists of 89.0% detached houses and 11.0% townhouses or apartments, maintaining the low density character of the area with a focus on detached homes that attract buyers seeking space. The estimated ratio of 627 residents per dwelling approval highlights a quiet, low activity development environment. Future projections indicate the suburb of Noarlunga Downs will add 293 residents by 2041 (using the latest quarterly estimate from AreaSearch). If current construction volumes persist, housing supply could fall behind population growth, which is likely to increase buyer competition and support upward price pressure.

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 — 3 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (4,031 at the 2021 Census → 4,082 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 (SAL41035). 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 Noarlunga Downs 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 Noarlunga Downs 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 Noarlunga Downs 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 (Jul 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.
