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 years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, released in 2023 and based on 2021 data, with adjustments made using weighted aggregation methods from LGA to SA2 levels.

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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates Gilberton has experienced around 6 dwellings receiving development approval each year over the past five financial years. This totals an estimated 34 homes. So far in FY-26, 3 approvals have been recorded.

Over these five years (FY-21 to FY-25), there has been an average of 2.7 new residents per year for each dwelling. The average construction cost value of new homes is $844,000, suggesting developers are targeting the premium market segment with higher-end properties. Compared to Greater Adelaide, Gilberton has around two-thirds the rate of new dwelling approvals per person while it ranks among the 87th percentile nationally in terms of assessed areas. Recent construction activity has intensified. New development consists of 33.0% detached houses and 67.0% attached dwellings, offering affordable entry pathways and attracting downsizers, investors, and first-time purchasers.

This marks a significant change from the current housing mix (currently 55.0% houses), reflecting reduced availability of development sites and shifting lifestyle demands and affordability requirements. With around 101 people per dwelling approval, Gilberton exhibits characteristics of a growth area. Future projections show Gilberton adding 255 residents by 2041, based on the latest AreaSearch quarterly estimate. At current development rates, housing supply may struggle to match population growth, potentially increasing buyer competition and supporting price increases.
