Gilbert Valley

Gilbert Valley is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Gilbert Valley's population was approximately 5,307 as of February 2026. This figure represents an increase of 291 people (5.8%) since the 2021 Census, which recorded a population of 5,016. The change is inferred from the estimated resident population of 5,168 in June 2024 and an additional 144 validated new addresses since the Census date. This results in a population density ratio of 3.2 persons per square kilometer. Gilbert Valley's growth rate exceeded that of the SA3 area (4.5%), indicating it as a growth leader in the region. Overseas migration was the primary driver of population growth during recent periods.

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, State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted using a weighted aggregation method from LGA to SA2 levels. Future demographic trends suggest lower quartile growth for locations outside capital cities. Gilbert Valley is expected to grow by 75 persons to reach approximately 5,382 by 2041, reflecting an overall reduction of 1.2% over the 17-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. In FY-26 so far, 12 approvals have been recorded. Over these five years, from FY-21 to FY-25, an average of only 0.6 people per year moved to the area for each dwelling built. This suggests that new construction is meeting or exceeding demand, providing buyers with more options and enabling population growth that could surpass current expectations.

The average expected construction cost value of these new homes is $265,000. Additionally, $6.7 million in commercial approvals have been registered this financial year, indicating the area's residential character. Compared to the rest of South Australia (SA), Gilbert Valley has seen slightly more development, with 39.0% above the regional average per person over the five-year period.

This preserves reasonable buyer options while sustaining existing property demand. All new construction in the area has been standalone homes, maintaining its traditional low density character and focusing on family homes that appeal to those seeking space. With around 210 people per approval, Gilbert Valley reflects a low-density area. Given that population is expected to remain stable or decline, the valley should see reduced pressure on housing, potentially creating opportunities for buyers.
