AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted using weighted aggregation from LGA to SA2 levels. Future demographic trends suggest lower quartile growth for non-capital city locations. Gilbert Valley is projected to grow by 81 persons to 2041, reflecting an overall gain of 1.1% over the 16-year period.

Residential development activity is lower than average in Gilbert Valley according to AreaSearch's national comparison of local real estate markets

Gilbert Valley has averaged approximately 25 new dwelling approvals each year over the past five financial years, totalling 128 homes. As of FY-26, 15 approvals have been recorded. The average number of people moving to the area per dwelling built over this period is 0.6. This suggests that new construction is meeting or exceeding demand, providing more options for buyers and potentially enabling population growth beyond current expectations.

The average expected construction cost value of these homes is $265,000. In FY-26, $6.7 million in commercial approvals have been registered, indicating the area's residential character. Compared to the rest of South Australia, Gilbert Valley has seen slightly more development, with 38.0% above the regional average per person over the past five years.

This preserves reasonable buyer options while sustaining existing property demand. All recent development has consisted of standalone homes, maintaining the area's traditional low density character and focusing on family homes that appeal to those seeking space. The location currently has approximately 210 people per dwelling approval, indicating a low density market. According to the latest AreaSearch quarterly estimate, Gilbert Valley is expected to grow by 58 residents through to 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers and potentially enabling growth that exceeds current forecasts.
