Klemzig

Population growth drivers in Klemzig are above average based on AreaSearch's ranking of recent, and medium to long-term trends

Based on ABS population updates and AreaSearch validation, Klemzig's population was estimated at 7,474 as of Feb 2026. This reflected an increase of 761 people since the 2021 Census, which reported a population of 6,713. The change was inferred from AreaSearch's resident population estimate of 6,982 following examination of ABS' June 2024 ERP data release and additional validated new addresses since the Census date. This resulted in a density ratio of 2,977 persons per square kilometer, placing Klemzig in the upper quartile nationally according to AreaSearch assessments. Klemzig's 11.3% growth since the 2021 census exceeded both state (9.0%) and Greater Adelaide figures, marking it as a regional growth leader. Overseas migration contributed approximately 74.0% of overall population gains during recent periods in the suburb.

AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, SA State Government's Regional/LGA projections by age category were used, based on 2021 data and released in 2023, with adjustments made employing a method of weighted aggregation from LGA to SA2 levels. Considering projected demographic shifts, Klemzig is expected to grow by 959 persons to 2041, reflecting a gain of 7.1% over the 17 years according to aggregated SA2-level projections.

Recent residential development output has been above average within Klemzig when compared nationally

AreaSearch analysis of ABS building approval numbers allocated from statistical area data shows Klemzig had approximately 39 new homes approved annually. Over the past five financial years, from FY21 to FY25, around 197 homes were approved, with an additional 25 approved so far in FY26. This indicates a healthy demand for housing, supporting property values, with an average of 2.2 people moving to the area per new home constructed over these years.

The average expected construction cost value of new homes is $379,000, suggesting developers are targeting the premium market segment. In FY26, $7.3 million in commercial approvals have been registered, reflecting the area's primarily residential nature. Compared to Greater Adelaide, Klemzig has around two-thirds the rate of new dwelling approvals per person and places among the 69th percentile nationally when assessed against other areas.

Recent construction comprises 90% detached dwellings and 10% townhouses or apartments, maintaining the area's suburban character with an emphasis on detached housing attracting space-seeking buyers. Interestingly, developers are building more traditional houses than the current mix suggests (68% at Census), indicating continued strong demand for family homes despite density pressures. The location has approximately 192 people per dwelling approval, suggesting an expanding market. Population forecasts indicate Klemzig will gain 532 residents by 2041, based on the latest AreaSearch quarterly estimate. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
