Hindmarsh Island

Hindmarsh Island lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

As per ABS population updates for the broader area and validated new addresses by AreaSearch, the suburb of Hindmarsh Island's estimated population was around 2,280 as of Feb 2026. This reflected an increase of 434 people since the 2021 Census, which reported a population of 1,846 people. The change was inferred from the resident population of 2,169 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 257 validated new addresses since the Census date. This level of population equated to a density ratio of 34 persons per square kilometer. Hindmarsh Island's growth of 23.5% since the 2021 census exceeded the Rest of SA (7.6%) and the SA4 region, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration contributing approximately 83.0% of overall population gains during recent periods.

AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and for areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category were adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Based on aggregated SA2-level projections, the suburb is expected to expand by 160 persons to 2041, reflecting a reduction of 7.7% in total over the 17 years.

AreaSearch assessment of residential approval activity sees Hindmarsh Island among the top 30% of areas assessed nationwide

Based on AreaSearch analysis using ABS building approval numbers from statistical area data, Hindmarsh Island has experienced around 64 dwellings receiving development approval per year. Over the past 5 financial years, between FY21 and FY25, approximately 324 homes were approved, with an additional 35 approved so far in FY26. On average, over these years, only 0.6 new residents per year were associated with each dwelling constructed.

This suggests that new supply is keeping pace with or exceeding demand, offering ample buyer choice and creating capacity for population growth beyond current forecasts. The average expected construction cost value of new dwellings was $401,000, indicating a focus on the premium market segment with higher-end properties. In FY26, there have been $6.8 million in commercial approvals, suggesting limited commercial development focus compared to residential. When comparing Hindmarsh Island's development activity per person to Rest of SA, it records 166.0% more activity, which is substantially higher than the national level, indicating strong developer confidence in the location. New building activity shows 97.0% standalone homes and 3.0% townhouses or apartments, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space.

With around 23 people per approval, Hindmarsh Island reflects a developing area. Given population projections showing stability or decline, it is expected that Hindmarsh Island should see reduced housing demand pressures in the future, benefiting potential buyers.
