AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 using 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 employing weighted aggregation methods. By 2041, the Hewett area is forecast to increase by 803 persons, reflecting a total increase of 21.7% over the 17-year period.

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

AreaSearch analysis of ABS building approval numbers in Hewett shows an average of around 7 dwelling approvals annually over the past five financial years, totalling approximately 35 homes. In FY26 to date, 18 approvals have been recorded. This results in about 4.3 people moving to the area per year for each dwelling built between FY21 and FY25, indicating significant demand exceeding new supply.

New properties are constructed at an average expected cost of $390,000, suggesting a focus on the premium segment with upmarket dwellings. Compared to Greater Adelaide, Hewett has substantially reduced construction activity, with 85.0% 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. Recent development has been entirely comprised of standalone homes, preserving the area's suburban nature and attracting space-seeking buyers. With around 206 people per dwelling approval, Hewett exhibits characteristics of a growth area.

According to AreaSearch's latest quarterly estimate, Hewett is projected to add approximately 699 residents by 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing buyer competition and supporting stronger price growth.
