Gilberton (SA)

Gilberton has seen population growth performance typically on par with national averages when looking at short and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since May 2026, the suburb of Gilberton's estimated population is around 1,566. This reflects an increase of 38 people (2.5%) since the 2021 Census, which reported a population of 1,528 people. The change is inferred from the resident population of 1,563, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and address validation since the Census date. This level of population equates to a density ratio of 2,485 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Population growth for the area was primarily driven by overseas migration that contributed approximately 83.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with a base year of 2022. For any SA2 areas not covered by this data, and for years post-2032, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Considering the projected demographic shifts, a population increase just below the median of statistical areas analysed by AreaSearch is expected for Gilberton (SA), with the area expected to grow by 154 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 9.6% in total over the 16 years.

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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Gilberton has experienced around 3 dwellings receiving development approval each year over the past 5 financial years ending FY-25. This totals an estimated 17 homes. So far in FY-26, recorded approvals stand at 1.

Over the past 5 financial years (FY-21 to FY-25), an average of approximately 0.8 new residents per year per dwelling constructed has been observed. This indicates that supply is meeting or surpassing demand, offering greater buyer choice and supporting potential population growth above projections. The average construction value of new homes over this period was $844,000, suggesting developers are targeting the premium market segment with higher-end properties. Relative to Greater Adelaide, Gilberton has significantly less development activity, 69.0% below the regional average per person as of FY-25. This scarcity typically strengthens demand and prices for existing properties. However, construction activity has intensified recently. Nationally, this level is also lower, reflecting market maturity and possible development constraints.

Recent construction in Gilberton comprises approximately 33.0% detached dwellings and 67.0% medium to high-density housing. This focus on higher-density living creates more affordable entry points, suiting downsizers, investors, and first-home buyers. This marks a significant departure from existing housing patterns, which currently consist of 55.0% houses, suggesting diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. With around 220 people per dwelling approval, Gilberton shows characteristics of a low-density area. Looking ahead, AreaSearch's latest quarterly estimate projects Gilberton to grow by approximately 151 residents through to 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.

Gilberton has a highly educated workforce with strong representation in professional services. The unemployment rate was 4.7% as of December 2025. Employment growth over the past year was estimated at 2.7%.

However, manufacturing is under-represented at 4.2% compared to Greater Adelaide's 7.0%.

In contrast, Greater Adelaide saw employment grow by 4.2% and unemployment fall by 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project national employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Gilberton's employment mix suggests local employment should increase by 7.6% over five years and 15.4% over ten years, though this is a simple weighting extrapolation for illustrative purposes only.
