Roseworthy

Roseworthy has seen population growth performance typically on par with national averages when looking at short and medium term trends

As of November 2025, the estimated population of Roseworthy is around 1,629. This figure reflects a growth of 588 people since the 2021 Census, which reported a population of 1,041. The increase is inferred from AreaSearch's estimate of the resident population at 1,453 in June 2024, based on ABS ERP data, and an additional 385 validated new addresses since the Census date. This results in a population density ratio of 68 persons per square kilometer. Roseworthy's growth rate of 56.5% since the 2021 census exceeds both the state (7.1%) and metropolitan area averages, making it a notable growth leader. Interstate migration contributed approximately 41.0% to overall population gains in recent periods, with natural growth and overseas migration also being positive factors.

AreaSearch uses 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 are adopted with adjustments made using weighted aggregation from LGA to SA2 levels. By 2041, the suburb is projected to have expanded by 291 persons based on aggregated SA2-level projections, reflecting a reduction of 14.6% in total over the 17 years.

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

The average construction cost value of these new homes is $390,000.

This financial year, $620,000 in commercial approvals have been registered, reflecting the area's residential nature.
