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 5,329 as of November 2025, according to AreaSearch's analysis. This figure represents an increase of 313 people, a 6.2% rise from the 2021 Census which recorded a population of 5,016. The change was inferred from the estimated resident population of 5,168 in June 2024 and an additional 142 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 (5.7%) during this period, indicating it as a growth leader in the region. Overseas migration was the primary driver of population growth.

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, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted employing weighted aggregation from LGA to SA2 levels. Future demographic trends suggest lower quartile growth for locations outside capital cities. Gilbert Valley is projected to grow by 75 persons to 2041, reflecting a reduction of 1.6% in total over the 17 years based on the latest annual ERP population numbers.

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 annually over the past five financial years, totalling 128 homes. As of FY-26, 12 approvals have been recorded. The average number of people moving to the area per year for each dwelling built over these five financial years (FY-21 to FY-25) is 0.6. New construction has matched or exceeded demand, providing more options for buyers and enabling population growth that may surpass current projections.

The average expected construction cost value of new homes is $265,000. In this financial year, $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 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 during this period comprised standalone homes, maintaining the area's traditional low-density character and focusing on family homes appealing to those seeking space. With around 210 people per approval, Gilbert Valley reflects a developing area. Given that population is expected to remain stable or decline, there should be reduced pressure on housing in Gilbert Valley, potentially creating opportunities for buyers.

The area may have limited local employment opportunities as Census working population vs resident population suggests. Between September 2024 and September 2025, employment levels increased by 0.9%, labour force by 2.1%, leading to a 1.1 percentage point rise in unemployment. In contrast, Rest of SA saw employment rise by 0.3%, labour force grow by 2.3%, and unemployment increase by 1.9 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project overall growth at 6.6% over five years and 13.7% over ten years, but industry-specific projections vary significantly. Applying these to Gilbert Valley's employment mix suggests local employment should increase by 5.0% over five years and 11.4% over ten years.
