Cheltenham (SA)

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

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since Feb 2026, Cheltenham's population is estimated at around 2,575. This reflects an increase of 339 people (15.2%) since the 2021 Census, which reported a population of 2,236 people. The change is inferred from the resident population of 2,421, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024, and an additional 24 validated new addresses since the Census date. This level of population equates to a density ratio of 2,258 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Cheltenham's growth of 15.2% since the 2021 census exceeded the state (9.0%), along with Greater Adelaide, marking it as a growth leader in the region. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 87.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, released in 2023 based on 2021 data, with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Anticipating future population dynamics, an above median population growth is projected for the suburb, with an increase of 515 persons expected by 2041 based on aggregated SA2-level projections, reflecting an increase of 11.8% in total over the 17 years.

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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Cheltenham has seen around 20 new homes approved annually. Approximately 100 homes have been approved over the past five financial years, from FY-21 to FY-25, with 14 approved so far in FY-26. This results in an average of 1.7 new residents per year per dwelling constructed during this period.

The supply and demand appear well-balanced, creating stable market conditions. New dwellings are developed at an average expected construction cost value of $320,000. In the current financial year, $6.1 million in commercial approvals have been registered, indicating limited commercial development focus compared to residential development. When measured against Greater Adelaide, Cheltenham maintains similar construction rates per person, preserving market equilibrium consistent with surrounding areas. New building activity shows 33.0% detached dwellings and 67.0% medium and high-density housing.

This shift from the area's existing housing composition (currently 81.0% houses) indicates decreasing availability of developable sites and reflects changing lifestyles, as well as the need for more diverse, affordable housing options. The location has approximately 103 people per dwelling approval, indicating an expanding market. Future projections show Cheltenham adding 304 residents by 2041, based on the latest AreaSearch quarterly estimate. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
