South Arm

Population growth drivers in South Arm are slightly above average based on AreaSearch's ranking of recent, and medium term trends

South Arm's population, as of February 2026, is approximately 4,680. This figure represents an increase of 64 people since the 2021 Census, which reported a population of 4,616. The growth was inferred from the estimated resident population of 4,657 in June 2024 and an additional 46 validated new addresses post-Census. This results in a population density of 63 persons per square kilometer. Overseas migration accounted for approximately 61.4% of overall population gains recently.

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 post-2032 growth by age group, Tasmania State Government's Regional/LGA projections from 2022 with a base year of 2021 are adopted, adjusted using weighted aggregation. Based on projected demographic shifts, South Arm is expected to have population growth just below the national median by 2041. The latest annual ERP population numbers project an increase of 363 persons, reflecting a total increase of approximately 7.3% over the 17-year period.

Residential development activity is lower than average in South Arm according to AreaSearch's national comparison of local real estate markets

South Arm averaged approximately 20 new dwelling approvals annually over the past five financial years, totalling 103 homes. As of FY-26, 6 approvals have been recorded. The area has seen an average of 0.9 people moving in per year for each dwelling built between FY-21 and FY-25. This indicates that new supply is keeping pace with or exceeding demand, offering ample buyer choice and creating capacity for population growth beyond current forecasts.

New properties are constructed at an average expected cost of $389,000, suggesting developers focus on the premium market with high-end developments. In FY-26, $672,000 in commercial approvals have been registered, indicating minimal commercial development activity compared to residential. When measured against Greater Hobart, South Arm shows approximately 75% of the construction activity per person and places among the 60th percentile of areas assessed nationally.

Recent building activity consists entirely of detached houses, preserving the area's low density nature with an emphasis on detached housing attracting space-seeking buyers. With around 246 people per dwelling approval, South Arm shows characteristics of a low density area. According to AreaSearch's latest quarterly estimate, South Arm is forecasted to gain 340 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.

Greater Hobart recorded a similar employment decline of 0.7% but had a slight labour force decline of 0.9%. Unemployment fell by 0.2 percentage points in Greater Hobart during this period. National employment forecasts from Jobs and Skills Australia, published in May-25, project national employment growth of 6.6% over five years and 13.7% over ten years.
