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
Kadina has an estimated 3,246 residents, up from 2,944 at the 2021 Census — a change of 302 people, or 10.3%. Growth has averaged 1.3% a year over five years. Interstate and internal migration accounts for 72.0% of that increase. Density is about 32 people per 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
As of Aug 2026, the population of the suburb of Kadina stands at approximately 3,246, according to AreaSearch evaluations combining regional ABS updates and address validations conducted since the Census. In comparison to the 2,944 people recorded at the 2021 Census, this represents an addition of 302 people (10.3%). This adjustment stems from an ERP resident figure of 3,201 derived from ABS releases in June 2025, alongside 51 validated new addresses registered since the Census. The suburb of Kadina features an open environment with a density of 31 persons per square kilometer.
With a 10.3% expansion since the 2021 census, the locality outpaced both the SA4 region and Rest of SA (6.2%), positioning it at the forefront of regional growth. Inbound interstate migration served as the primary catalyst, delivering approximately 72.0% of net increases in recent times, supplemented by positive contributions from overseas migration and natural growth. Long-term demographic forecasts utilize the 2024 ABS/Geoscience Australia SA2 modeling with a 2022 base year, complemented for unlisted SA2 areas and periods post-2032 by the SA State Government's 2023 Regional/LGA age-cohort releases based on 2021 figures, integrated through weighted LGA to SA2 growth aggregation. Future outlooks indicate the suburb of Kadina will track above the non-capital median, adding 362 persons by 2041 according to aggregated SA2 modeling, which translates to a cumulative rise of 9.8% across the 16 years.
Frequently Asked Questions - Population
81 new dwellings have been approved in Kadina over the past five years, an average of 16 a year. That is 3.9 approvals per 1,000 residents. Approvals are currently running at an annualised 9, well below 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
Residential building approval metrics compiled by AreaSearch from ABS data indicate an annual pipeline of around 16 new dwellings in Kadina, totaling an estimated 81 homes across the past 5 financial years (between FY-21 and FY-25), with 9 approved to date in FY-25. Across the past 5 financial years (between FY-21 and FY-25), the locality absorbed an average of 2.9 new residents per year for every constructed home, highlighting strong underlying demand. The expected construction cost for new dwellings averages $476,000, reflecting developer emphasis on higher-end residential stock. Concurrently, commercial approvals totaling $1.8 million this financial year underline the predominantly residential focus of local development.
Per capita residential construction in Kadina remains subdued, tracking 64.0% below the regional standard seen across Rest of SA. Such limited supply additions tend to underpin values across the existing housing stock. All recent approvals have consisted exclusively of detached houses, reinforcing a low-density urban footprint oriented toward spacious family living. With approximately 301 people per dwelling approval, the township retains capacity for ongoing expansion. Demographic projections based on the latest AreaSearch quarterly estimate suggest Kadina will add 317 residents through to 2041. Ongoing building activity is positioned to satisfy this projected requirement, sustaining accommodating conditions for purchasers while offering headroom to support growth beyond current projections.

Daddow Court and Abbott Drive Residential Development
Rezoning of 28 hectares of land to accommodate at least 227 new low-density residential allotments. This privately-led rezoning aims to support the growing population and demand for housing in the Yorke Peninsula.
1,300 residents of Kadina are employed, from a labour force of 1,400. Unemployment sits at 7.1%, with participation at 51.2%. 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 2,938, about 91% 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 labor market presents a mix of blue and white-collar roles with substantial representation in essential services, showing an estimated 4.4% employment growth over the past year and an unemployment rate of 7.1%, according to AreaSearch data. As of March 2026, employed residents total 1,300, while joblessness sits 1.6% higher than the 5.5% recorded in Regional SA. Labor force participation is also notably lower at 51.2% versus 58.3% across Regional SA. Remote working uptake was modest at 7.1% at the Census, an outcome potentially influenced by Covid-19 restrictions. Resident workforce distribution is centered primarily around health care & social assistance, retail trade, and education & training.
The township displays a pronounced concentration in health care & social assistance, where employment concentration is 1.3 times the regional standard. In contrast, agriculture, forestry & fishing accounts for 7.9% of local workers compared to 14.5% regionally. Comparing resident workers against the local working population at the Census suggests an economy reliant on external job markets. AreaSearch evaluation of ABS and SALM figures over the 12-month period shows local employment rising by 4.4% alongside a 3.9% expansion in the labour force, delivering a 0.6 percentage points reduction in unemployment. Over the same timeline, Regional SA saw employment grow by 1.2% and the labour force lift by 2.6%, resulting in a 1.4 percentage point rise in unemployment. Long-term outlooks from Jobs and Skills Australia as of Mar-26 project nationwide employment gains of 6.6% over five years and 13.7% over ten years. Weighting these sectoral trajectories against Kadina's industrial profile indicates potential local job expansion of 6.2% over five years and 13.1% over ten years (representing an illustrative weighted calculation that excludes specific local demographic projections).

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 — 51 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,944 at the 2021 Census → 3,246 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 Aug 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.
