AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. 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 a method of weighted aggregation of population growth from LGA to SA2 levels. Looking ahead, significant population increases in top quartile statistical areas across the nation are forecast, with Hewett expected to increase by 807 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 20.9% over the 17 years.

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

AreaSearch analysis of ABS building approval numbers indicates Hewett has received approximately 7 dwelling approvals annually over the past five financial years, totalling an estimated 35 homes. As of FY-26, 18 approvals have been recorded. On average, about 4.3 people have moved to the area per year for each dwelling built between FY-21 and FY-25.

This demand significantly exceeds new supply, typically leading to price growth and increased buyer competition. The average construction value of new properties is $390,000, indicating a focus on premium segment development with upmarket properties. Compared to Greater Adelaide, Hewett has shown substantially reduced construction activity, 85.0% below the regional average per person. This limited supply generally supports stronger demand and values for established properties, although building activity has accelerated in recent years. Nationally, Hewett's level of new supply is also lower, reflecting market maturity and possible development constraints.

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 206 people per dwelling approval, Hewett exhibits characteristics of a growth area. According to AreaSearch's latest quarterly estimate, Hewett is projected to add 679 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.
