Balhannah

Population growth drivers in Balhannah are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

As of Nov 2025, Balhannah's population is estimated around 1,629, a decrease of 127 people (7.2%) since the 2021 Census which reported 1,756 people. This decline reflects AreaSearch's estimation of 1,607 residents based on ABS ERP data release in June 2024 and validation of three new addresses post-Census date. The population density is approximately 51 persons per square kilometer. Interstate migration contributed about 54% to recent population gains. For projections, AreaSearch uses ABS/Geoscience Australia figures released in 2024 with a base year of 2022 for each SA2 area; for other areas and years post-2032, South Australian Government's Regional/LGA projections based on 2021 data are adopted.

By 2041, Balhannah is projected to increase by 266 persons, reflecting a total growth of 28.2% over the 17-year period.

AreaSearch assessment of residential development drivers sees a low level of activity in Balhannah, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers indicates Balhannah averaged approximately 4 new dwelling approvals annually. Between financial years FY21 to FY25, around 21 homes were approved, with none recorded so far in FY26. This averages out to about 3.6 people moving to the area per year for each dwelling built over these five years.

Demand has significantly outpaced supply, which usually puts upward pressure on prices and increases competition among buyers. In FY26, there have been $2.5 million worth of commercial approvals, indicating the area's primarily residential nature. Compared to Greater Adelaide, Balhannah has seen significantly less development activity, 78.0% below the regional average per person. This scarcity typically strengthens demand and prices for existing properties. Nationally, this activity is also below average, suggesting possible planning constraints.

Recent development has been entirely standalone homes, preserving the area's low density nature and attracting space-seeking buyers. As of now, there are estimated to be 3624 people in the area per dwelling approval. By 2041, Balhannah is forecasted to gain approximately 460 residents. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.

AreaSearch assessment positions Balhannah ahead of most Australian regions for employment performance

Balhannah has a well-educated workforce with prominent representation in essential services sectors. The unemployment rate is 3.0% and there has been an estimated employment growth of 1.5% over the past year, according to AreaSearch's aggregation of statistical area data.

As of June 2025969 residents are employed while the unemployment rate is 1.0% lower than Greater Adelaide's rate of 4.0%. Workforce participation in Balhannah is similar to Greater Adelaide's 61.7%. The dominant employment sectors among residents include health care & social assistance, education & training, and retail trade. Notably, agriculture, forestry & fishing employs a share that is 3.5 times the regional level.

However, health care & social assistance employs only 14.7% of local workers, which is lower than Greater Adelaide's 17.7%. The area may offer limited local employment opportunities, as indicated by the count of Census working population versus resident population. Over a 12-month period ending in June 2025, employment increased by 1.5% while labour force grew by 1.6%, resulting in an unemployment rate rise of 0.2 percentage points. In comparison, Greater Adelaide recorded employment growth of 2.1%. Jobs and Skills Australia's national employment forecasts from Sep-22 suggest potential future demand within Balhannah. These projections estimate national employment to expand by 6.6% over five years and 13.7% over ten years. Applying these industry-specific projections to Balhannah's employment mix suggests local employment should increase by 6.4% over five years and 13.4% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not consider localised population projections.
