Klemzig

An assessment of population growth drivers in Klemzig reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of November 2025, the estimated population of Klemzig is around 151,806, reflecting a 9,288 person increase since the 2021 Census. The 2021 Census reported a population of 142,518 in the suburb. This growth represents a 6.5% increase and is inferred from AreaSearch's estimation of the resident population at 6,902 based on the latest ERP data release by the ABS (June 2024), along with an additional 21 validated new addresses since the Census date. This results in a density ratio of 60,480 persons per square kilometer, providing significant space per person and potential room for further development. Klemzig's growth rate of 6.5% since the census is within 0.3 percentage points of the non-metro area (6.8%), indicating competitive growth fundamentals. Overseas migration was the primary driver of population gains in recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted with adjustments made using a method of weighted aggregation of population growth from LGA to SA2 levels. Future population trends suggest an increase just below the median of regional areas nationally, with the suburb expected to increase by 7,848 persons to 2041 based on aggregated SA2-level projections, reflecting an overall increase of 7.8% over the 17 years.

AreaSearch assessment of residential development activity positions Klemzig among the top 25% of areas assessed nationwide

AreaSearch analysis of ABS building approval numbers shows Klemzig had approximately 465 new homes approved annually over the past five financial years, totalling around 2,325 homes. As of FY-26227 approvals have been recorded. On average, each dwelling constructed between FY-21 and FY-25 accommodated about 1.7 new residents per year. This indicates a balanced supply and demand market, supporting stable conditions.

The average construction value for new dwellings is $763,000, suggesting developers focus on the premium market with high-end developments. In FY-26, commercial approvals totalled $1209.7 million, reflecting high local commercial activity. Compared to Rest of SA, Klemzig has roughly two-thirds the rate of new dwelling approvals per person but ranks among the 132nd percentile nationally. New development consists mainly of detached dwellings (95.0%) with a smaller proportion of attached dwellings (5.0%), maintaining the area's low density nature and attracting space-seeking buyers.

This represents a significant shift from the current housing mix, which is predominantly houses (180.0%). The estimated population per dwelling approval is 340 people, reflecting Klemzig's quiet development environment. Population projections indicate stability or decline in Klemzig, potentially reducing housing demand pressures and benefiting potential buyers.

Despite maintaining a low unemployment rate of 3.9%, Klemzig has experienced recent job losses, resulting in a below average employment performance ranking when compared nationally

Klemzig has a skilled workforce with notable representation in essential services sectors. Its unemployment rate was 3.9% as of June 2025, according to AreaSearch's aggregation of statistical area data.

The area had 37,982 residents employed while the unemployment rate was 0.7% lower than Rest of SA's rate of 4.6%. Workforce participation in Klemzig was high at 106.4%, compared to Rest of SA's 54.1%. Employment among residents is concentrated in agriculture, forestry & fishing, health care & social assistance, and retail trade. Agriculture, forestry & fishing employment levels were particularly notable, at 2.7 times the regional average.

Mining employed only 2.2% of local workers, below Rest of SA's 2.9%. The worker-to-resident ratio was substantial, indicating significant employment opportunities. Between June 2024 and June 2025, labour force decreased by 1.9%, employment declined by 2.9%, causing unemployment rate to rise by 1 percentage point. In contrast, Rest of SA saw a 1.2% employment contraction, 0.1% labour force growth, and a 1.2 percentage point increase in unemployment. Jobs and Skills Australia's national employment forecasts from Sep-2022 project overall employment expansion by 6.6% over five years and 13.7% over ten years. Applying these projections to Klemzig's employment mix suggests local employment should increase by 5.2% over five years and 11.7% over ten years, though this is a simple weighting extrapolation for illustrative purposes only.
