Somerton Park

An assessment of population growth drivers in Somerton Park reveals an overall ranking slightly below national averages considering recent, and medium term trends

The population of the Somerton Park statistical area (Lv2), as estimated by AreaSearch, was around 6,254 as of November 2025. This figure reflects a growth of 443 people since the Census in 2021, which reported a population of 5,811. The increase is inferred from an estimated resident population of 6,069 by AreaSearch following examination of the latest ERP data release by the ABS (June 2024), along with four validated new addresses since the Census date. This results in a population density ratio of 2,792 persons per square kilometer, placing Somerton Park in the upper quartile relative to national locations assessed by AreaSearch. The area's growth rate of 7.6% since the 2021 census exceeded the SA4 region's growth rate of 7.3%. Overseas migration was the primary driver behind this population increase.

AreaSearch employs 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, SA State Government's Regional/LGA projections by age category are used, adjusted through a method of weighted aggregation from LGA to SA2 levels. According to these projections, the Somerton Park (SA2) is expected to grow by 899 persons to reach an estimated population of 7,153 by 2041, reflecting a total gain of 11.7% over the 17-year period.

AreaSearch analysis of residential development drivers sees Somerton Park recording a relatively average level of approval activity when compared to local markets analysed countrywide

Somerton Park averaged approximately 32 new dwelling approvals annually based on AreaSearch analysis of ABS building approval numbers. Between FY-21 and FY-25, around 160 homes were approved, with an additional 10 approved in FY-26 to date. Each year, about 1.4 new residents are estimated per dwelling constructed over the past five financial years.

This suggests a balance between supply and demand, maintaining stable market conditions. Developers target the premium market segment as new dwellings average $631,000 in construction cost value. In FY-26, commercial approvals totalled $5.7 million, indicating Somerton Park's residential character. Compared to Greater Adelaide, Somerton Park has 13.0% less new development per person but ranks among the 68th percentile nationally. New development consists of 41.0% detached houses and 59.0% attached dwellings, marking a shift from existing housing patterns (currently 63.0% houses).

This trend towards denser development offers accessible entry options for downsizers, investors, and first-time buyers, potentially responding to diminishing developable land availability and evolving lifestyle preferences. Somerton Park has approximately 198 people per dwelling approval, indicating an expanding market. Future projections estimate Somerton Park will add 729 residents by 2041 based on the latest AreaSearch quarterly estimate. With current construction levels, housing supply should meet demand adequately, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
