This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Sales Detail
Netherby (SA) has an estimated 1,502 residents. That puts 1,231 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 demographics updates for the broader region alongside address registries verified by AreaSearch since the Census, the suburb of Netherby (SA) has a calculated population of approximately 1,502 as of May 2026. This represents a decline of 8 people (0.5%) relative to the 2021 Census, when the head count stood at 1,510 people. This adjustment is derived from a resident headcount of 1,499, calculated by AreaSearch using the June 2025 ABS ERP publication and subsequent address checks. Such population figures produce a density of 1,231 persons per square kilometer, which exceeds the typical level observed across the country by AreaSearch.
Inward overseas migration functioned as virtually the sole driver of population growth locally in recent times. AreaSearch incorporates SA2 regional projections developed by the ABS and Geoscience Australia in 2024 using 2022 as the launch year. For locations lacking this coverage, and for periods beyond 2032, regional LGA forecasts categorized by age from the SA Government (published in 2023 utilizing 2021 baselines) are implemented, adjusted through weighted aggregation of population shifts from LGA to SA2 divisions. Looking at long-term outlooks, expansion in the lower quartile of tracked regions is expected, with the suburb of Netherby (SA) projected to add 27 persons by 2041 via aggregated SA2 metrics, representing a total rise of 1.6% over the 16 years.
Frequently Asked Questions - Population
62 new dwellings have been approved in Netherby (SA) over the past five years, an average of 12 a year. That is 8.3 approvals per 1,000 residents. Few approvals have been recorded in the most recent months, well below the longer-run average; the latest ABS periods are still being reported. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.
Detail
Analysis by AreaSearch of ABS residential building approvals indicates that Netherby has averaged roughly 12 approved residential properties annually, amounting to a total of 62 homes over the preceding 5 financial years. Throughout FY-26 to date, no approvals have been registered. Because the population declined during the prior term, the volume of new housing has likely matched local demand, providing buyers with suitable options. Furthermore, commercial approvals reached $1.8 million this financial year, which highlights a primary emphasis on residential properties. Netherby registers 142.0% more new residential approvals per capita than Greater Adelaide, offering purchasers a wide selection, even though construction momentum has decelerated lately.
Recent building projects consist of 79.0% separate houses and 21.0% apartments or townhouses, reinforcing the suburban character with a high proportion of detached homes ideal for residents needing extra space. There are roughly 231 people for every residential approval, demonstrating a low-density property market. Projections indicate that Netherby will expand by 24 residents by 2041, starting from the most recent quarterly calculation by AreaSearch. Under current construction trends, new dwelling additions are expected to easily satisfy housing demand, supporting favorable purchasing conditions and potentially enabling faster population expansion than currently anticipated.

884 residents of Netherby (SA) are employed, from a labour force of 892. Unemployment sits at 0.9%, with participation at 71.8%. Weighted for its industry mix, the area's sectors are forecast to grow about 7.3% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
The local workforce is highly qualified, featuring a strong concentration of professional services, an unemployment rate of only 0.9%, and an estimated job growth rate of 4.9% over the past year based on regional data compiled by AreaSearch. In March 2026884 local citizens were employed, with the local jobless rate sitting 2.9% below the 3.8% recorded across Greater Adelaide, while workforce participation reached an elevated 71.8% compared to 66.6% in Greater Adelaide. Census statistics show that a moderate 16.9% of local workers operated from home, though this data should be interpreted with caution due to COVID-19 pandemic restrictions.
The primary employment fields for residents are health care & social assistance, professional & technical, and education & training. The community shows an especially heavy concentration in professional & technical fields, with employment levels reaching 1.8 times the metropolitan average. Conversely, builders and construction workers comprise a smaller share at 4.3% compared to the regional average of 8.7%. The presence of 0.7 jobs for every resident at the Census indicates a higher-than-average volume of local employment opportunities. Based on AreaSearch compiler research of SALM and ABS statistics for the broader area, the year ending March 2026 saw employment climb by 4.9% and the labor force rise by 4.7%, which reduced the unemployment rate by 0.2 percentage points. Over the same timeframe, Greater Adelaide saw employment grow by 4.2% and its labor force expand by 4.0%, leading to a 0.2 percentage point reduction in unemployment. Employment projections issued by Jobs and Skills Australia in May-25 offer additional perspectives on prospective local demand in Netherby. These forecasts, spanning five and ten-year intervals, are combined with local industry percentages to model growth. Nationally, employment is predicted to grow by 6.6% over five years and 13.7% over ten years, though industry rates differ. Applying these trends to the local occupation structure suggests Netherby's jobs should rise by 7.3% over five years and 14.9% over ten years, representing a basic weighted extrapolation that does not incorporate localized population 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. The headline figure is therefore a current estimate for May 2026, not a 2021 count (1,510 at the 2021 Census → 1,502 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.
