Sales Detail
Port Noarlunga South has an estimated 3,118 residents, up from 3,058 at the 2021 Census — a change of 60 people, or 2.0%. Growth has averaged 0.5% a year over five years, slower than 80% of areas nationally. That puts 974 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 evaluations of ABS population updates for the wider region and new address verifications by AreaSearch since the Census, the suburb of Port Noarlunga South has an estimated residency of roughly 3,118 as of May 2026. This represents an expansion of 60 individuals (2.0%) from the 2021 Census, which documented a population of 3,058 residents. This shift is derived from a resident headcount of 3,116 calculated by AreaSearch using the ABS's June 2025 ERP release alongside 9 validated new addresses registered since the Census. Such a population size results in a density of 974 persons per square kilometer, matching typical averages across evaluated areas.
Throughout the previous ten years, the suburb of Port Noarlunga South has shown steady development with a 1.1% compound annual growth rate, exceeding the SA3 region. This demographic expansion was primarily fueled by overseas arrivals, who accounted for approximately 41.0% of the total growth, though all contributors, including natural increases and interstate movement, registered positively. AreaSearch utilizes ABS and Geoscience Australia forecasts for each SA2 zone, published in 2024 with a 2022 baseline. For SA2 zones lacking this data and for timeframes after 2032, regional and LGA projections by age bracket released by the SA State Government in 2023 (utilizing 2021 records) are applied, modified through a weighted aggregation method of population increases from LGA to SA2 divisions. Looking ahead, population growth exceeding the median for Australian statistical areas is anticipated, with the suburb of Port Noarlunga South projected to add 452 individuals by 2041 under aggregated SA2 models, marking a 14.4% overall rise across the 16 years.

Detail
AreaSearch's analysis of ABS building approvals assigned from statistical data indicates that Port Noarlunga South has maintained an average of approximately 22 residential approvals each year, summing to an estimated 114 dwellings over the past 5 financial years. Thus far in FY-26, 6 approvals have been logged. With an average of only 0.7 new residents moving in per finished home annually over the 5 financial years from FY-21 to FY-25, new builds are keeping pace with or exceeding demand, broadening choices for buyers and allowing population gains to potentially outpace current forecasts, with new dwellings carrying an average construction value of $380,000, showing a focus by developers on upmarket, premium properties.
Furthermore, commercial approvals worth $237,000 have been logged during this financial year, highlighting the predominantly residential character of the locality. Compared to Greater Adelaide, development activity per capita in Port Noarlunga South is 53.0% higher, offering purchasers significant choice despite a recent slowdown in construction. The incoming supply consists of 90.0% standalone houses and 10.0% medium to high-density options, maintaining the suburban profile of the community with a clear focus on detached houses that appeal to buyers seeking space. Representing a highly established market, Port Noarlunga South records approximately 1245 people for each residential approval. Demographic projections indicate that Port Noarlunga South will add 450 residents by 2041 relative to the most recent quarterly estimate from AreaSearch. With the current pace of construction, the supply of new housing is anticipated to easily satisfy demand, creating favorable buyer conditions and potentially underpinning growth beyond official population forecasts.

1,710 residents of Port Noarlunga South are employed, from a labour force of 1,767. Unemployment sits at 3.2%, with participation at 68.4%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.7% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 2,483, about 80% 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
Port Noarlunga South features a skilled workforce with well-represented essential services sectors, an unemployment rate of 3.2%, and an estimated employment growth of 3.6% over the past year, according to AreaSearch aggregation of statistical area data. As of March 2026, 1,710 residents are employed while the unemployment rate stands at 0.7% below Greater Adelaide's rate of 3.8%, and workforce participation remains broadly similar to Greater Adelaide's 66.6%. Census responses indicate that only 10.6% of residents worked from home, although the effects of Covid-19 lockdowns should be considered when interpreting this figure.
The primary sectors employing local residents are healthcare and social assistance, construction, and retail trade. The community shows a strong concentration in construction, with an employment share 1.6 times higher than the regional average. On the other hand, professional and technical services are underrepresented, making up 5.4% of the workforce compared to the metropolitan average of 7.3%. Comparing the resident workforce to the local working population suggests that local employment opportunities within the immediate area are limited. Based on AreaSearch assessments of SALM and ABS statistics aggregated from the broader region, the year ending March 2026 saw employment levels rise by 3.6% and the labor force grow by 3.5%, leading to a decrease of 0.1 percentage points in the unemployment rate. This differs from Greater Adelaide, which experienced a 4.2% lift in employment, a 4.0% increase in the labor force, and a 0.2 percentage point drop in unemployment. National employment projections from Jobs and Skills Australia published in May-25 offer additional perspective on prospective local demands in Port Noarlunga South. These five and ten-year forecasts have been applied to the local workforce structure to model future trends. Globally, national employment is projected to grow by 6.6% over five years and 13.7% over ten years, though these trajectories vary widely by industry. Projecting these industry-specific trends onto the occupational mix of Port Noarlunga South indicates that local employment will expand by 6.7% over five years and 13.8% over ten years, using a basic weighted extrapolation that does not account for localized population growth factors.

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 — 9 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (3,058 at the 2021 Census → 3,118 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.
