Whyalla

Whyalla has shown very soft population growth performance across periods assessed by AreaSearch

Based on AreaSearch's analysis, Whyalla's population is around 21,821 as of Feb 2026. This reflects an increase of 667 people (3.2%) since the 2021 Census, which reported a population of 21,154 people. The change is inferred from the estimated resident population of 21,764 from the ABS as of June 2024 and an additional 72 validated new addresses since the Census date. This population level equates to a density ratio of 533 persons per square kilometer, providing significant space per person and potential room for further development. Whyalla's 3.2% growth since the census positions it within 2.5 percentage points of the SA4 region (5.7%), demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by overseas migration, which contributed approximately 90.8% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and for years post-2032, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Considering the projected demographic shifts, lower quartile growth of Australia's non-metropolitan areas is anticipated, with the area expected to increase by 764 persons by 2041 based on the latest annual ERP population numbers, reflecting a gain of 3.2% in total over the 17 years.

The level of residential development activity in Whyalla is very low in comparison to the average area assessed nationally by AreaSearch

Whyalla has seen around 24 new homes approved annually, with 120 homes approved over the past 5 financial years (between FY-21 and FY-25) and 9 so far in FY-26. As the area has experienced population decline, new supply has likely been keeping up with demand, offering good choice to buyers, while new homes are being built at an average value of $296,000. There have also been $126.2 million in commercial approvals this financial year, demonstrating high levels of local commercial activity.

Compared to the rest of SA, Whyalla has significantly less development activity (66.0% below regional average per person). This limited new supply generally supports stronger demand and values for established properties, though building activity has accelerated in recent years. This level is similarly under the national average, indicating the area's established nature and suggesting potential planning limitations. New building activity shows 90.0% detached dwellings and 10.0% medium and high-density housing, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. Notably, developers are constructing more detached housing than the existing pattern implies (56.0% at Census), reflecting persistent strong demand for family homes amid densification trends. The estimated count of 715 people in the area per dwelling approval reflects its quiet, low activity development environment.

Future projections show Whyalla adding 707 residents by 2041 (from the latest AreaSearch quarterly estimate). Present construction rates appear balanced with future demand, fostering steady market conditions without excessive price pressure.

Whyalla has limited levels of nearby infrastructure activity, ranking in the 15thth percentile nationally

Employment conditions in Whyalla face significant challenges, ranking among the bottom 10% of areas assessed nationally

Whyalla possesses a balanced workforce spanning white and blue collar employment, with manufacturing and industrial sectors strongly represented, and an unemployment rate of 13.7%. As of December 2025, 9,186 residents are in work while the unemployment rate is 8.0% above Regional SA's rate of 5.7%, showing room for improvement, and workforce participation is on par with Regional SA's 58.8%. Based on Census responses, a low 2.2% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Employment among residents is concentrated in manufacturing, health care and social assistance, and retail trade. The area demonstrates a particularly notable concentration in manufacturing, with employment levels at 1.8 times the regional average. In contrast, agriculture, forestry and fishing employs just 0.4% of local workers, below Regional SA's 14.5%. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, the 12-month period saw the labour force increasing by 1.7% while employment declined by 7.0%, causing the unemployment rate to rise by 8.0 percentage points. In contrast, Regional SA experienced employment growth of 0.7% and labour force growth of 3.1%, with a 2.2 percentage point rise. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Whyalla. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Whyalla's employment mix suggests local employment should increase by 5.4% over five years and 12.3% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).

Income levels sit below national averages according to AreaSearch assessment

As per AreaSearch's latest postcode level ATO data released for FY-23, the Whyalla SA2's median income among taxpayers is $57,826, with an average of $68,414.

Based on Wage Price Index growth of 8.8% since FY-23, current estimates would be approximately $62,915 (median) and $74,434 (average) as of September 2025. According to 2021 Census figures, household, family and personal incomes in Whyalla all fall between the 12th and 17th percentiles nationally.

While housing costs are modest with 87.1% of income retained, the total disposable income ranks at just the 16th percentile nationally.
