Hewett

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

As of May 2026, the estimated population of the suburb of Hewett is around 3,072 people. This figure reflects an increase of 111 individuals since the 2021 Census, which reported a population of 2,961 people. The latest estimate by AreaSearch, following examination of the ABS's June 2025 ERP data release and validation of new addresses, is 3,012 residents. This results in a population density ratio of 1,828 persons per square kilometer, exceeding the national average assessed by AreaSearch. The primary driver for this growth was interstate migration, contributing approximately 41.0% of overall population gains during recent periods.

However, all factors including natural growth and overseas migration were positive contributors. AreaSearch employs 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, based on 2021 data and released in 2023, with adjustments made using weighted aggregation methods. Looking ahead, significant population increases are forecast for top quartile statistical areas nationally. By 2041, Hewett is projected to increase by 711 persons, reflecting a total increase of 21.2% over the 16-year period, based on aggregated SA2-level projections.

AreaSearch analysis of residential development drivers sees Hewett recording a relatively average level of approval activity when compared to local markets analysed countrywide

AreaSearch analysis of ABS building approval numbers for Hewett indicates an average of around 7 dwelling approvals annually over the past 5 financial years from FY-21 to FY-25, totalling approximately 37 homes. In FY-26 so far, 23 approvals have been recorded. An estimated 1.9 new residents per year per dwelling constructed was observed between FY-21 and FY-25, suggesting a balanced supply and demand in the market. However, this has moderated to 1 person per dwelling over the past 2 financial years, indicating an improved supply-demand balance.

The average construction value of new homes is $390,000, reflecting a developer focus on the premium segment with upmarket properties. Compared to Greater Adelaide, Hewett shows significantly reduced construction activity, at 83.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established properties, although building activity has accelerated in recent years. Additionally, recent development has been entirely comprised of standalone homes, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. With around 188 people per dwelling approval, Hewett exhibits characteristics of a low density area.

According to AreaSearch's latest quarterly estimate, Hewett is projected to add 651 residents by 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
