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
Osborne (SA) has an estimated 1,981 residents, up from 1,951 at the 2021 Census — a change of 30 people, or 1.5%. That puts 1,395 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
Osborne (SA) has an estimated population of 1,981 as of May 2026, according to analysis of ABS population revisions for the surrounding region combined with new address validations by AreaSearch since the Census. This represents an addition of 30 people (1.5%) compared to the 2021 Census, which registered 1,951 individuals. The adjustment is derived from a resident count of 1,980, calculated by AreaSearch using the ABS ERP release from June 2025 alongside 5 validated new addresses since the Census. This population level results in a density of 1,395 persons per square kilometer, exceeding the typical figure for locations analyzed nationally by AreaSearch.
Growth locally was mostly fueled by overseas arrivals, accounting for roughly 47.0% of the net gains, though all factors, including interstate arrivals and natural growth, registered positive results. AreaSearch utilizes ABS/Geoscience Australia projections for each SA2, which were published in 2024 using 2022 as the baseline. For SA2 territories lacking this coverage, and for years after 2032, regional/LGA projections by age group from the SA State Government (released in 2023 utilizing 2021 data) are applied, modified via a weighted aggregation of expansion from LGA to SA2 scale. Looking at future trends for the suburb of Osborne (SA), the population is projected to expand at a rate slightly below the national median for statistical regions, adding 188 residents by 2041 under aggregated SA2 projections, which represents a total increase of 9.4% over the 16 years.
Frequently Asked Questions - Population
Detail
Osborne has averaged roughly 2 new residential approvals annually based on building approval statistics from the ABS allocated from broader statistical areas, with a total of 10 homes approved over the 5 financial years from FY-21 to FY-25, and 4 approvals recorded during FY-26. Because only 1 person per year moved to the area for every new dwelling constructed over the 5 financial years from FY-21 to FY-25, supply is keeping pace with or outstripping demand, which increases options for buyers and allows for population gains beyond projections; new builds average $479,000 in value, pointing to a developer focus on higher-end residential offerings.
Commercial approvals reached $7.5 million this financial year, emphasizing that the locality remains predominantly residential. Osborne exhibits significantly lower construction activity compared to Greater Adelaide, sitting 88.0% below the metropolitan average on a per-capita basis. This restricted level of building typically supports demand and valuations for established housing. It is also lower than the national average, indicating the established nature of the suburb and suggesting possible planning constraints. Recent activity has consisted entirely of detached houses, maintaining a suburban profile dominated by family residences for buyers desiring space. The preference for detached housing in new approvals exceeds the existing mix (85.0% at the Census), highlighting persistent demand for family properties even as density pressures grow. With approximately 989 residents for every approval, the area shows its mature, established character. Forecasts indicate that the population will increase by 187 residents up to 2041, based on the latest quarterly estimate from AreaSearch. If building activity continues at its current pace, the housing supply might fall short of population growth, which could increase competition among purchasers and support stronger appreciation in prices.

955 residents of Osborne (SA) are employed, from a labour force of 1,027. Unemployment sits at 7.0%, with participation at 61.6%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.2% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 1,645, about 83% 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
The local workforce is evenly divided between white-collar and blue-collar roles, with a strong presence in essential services, a jobless rate of 7.0%, and a 7.5% estimated rise in employment over the last year, compiled from statistical area data by AreaSearch. In March 2026, employed residents numbered 955, while the unemployment rate was 3.2% higher than the Greater Adelaide level of 3.8%, showing room for improvement; workforce participation was also lower (61.6% compared to 66.6% in Greater Adelaide). Census data indicates that a low 8.3% of workers worked from home, though this may have been influenced by COVID-19 lock-downs.
The top industries employing local residents are health care & social assistance, manufacturing, and retail trade. The suburb displays a strong concentration in transport, postal & warehousing, where the employment proportion is 2.0 times the metropolitan average. Conversely, professional & technical roles account for only 5.1% of workers, below the 7.3% seen across Greater Adelaide. The count of Census workers versus resident workers suggests the area is mostly residential with limited local jobs. Based on SALM and ABS statistics aggregated by AreaSearch, the 12-month period saw employment rise by 7.5% while the labour force expanded by 4.7%, leading to a 2.5 percentage point drop in the unemployment rate. This outpaced Greater Adelaide, where employment increased by 4.2%, the labor force expanded by 4.0%, and unemployment decreased by 0.2 percentage points. Forecasts from Jobs and Skills Australia from May-25 provide further context for future labour demand. These five and ten-year projections have been applied to the local workforce mix to model future growth. Nationally, employment is projected to grow by 6.6% over five years and 13.7% over ten years, though rates vary by industry. Weighting these projections to the local industry mix suggests employment among residents should grow by 6.2% over five years and 13.1% over ten years, using a simple weighting extrapolation that does not account for local population changes.

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 — 5 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (1,951 at the 2021 Census → 1,981 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.
