Mallala

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

Based on AreaSearch's analysis, Mallala's population was around 3,583 as of February 2026. This reflected an increase of 248 people, representing a 7.4% rise since the 2021 Census, which reported a population of 3,335 people. The change was inferred from the estimated resident population of 3,523 from the ABS as of June 2024 and an additional 43 validated new addresses since the Census date. This level of population resulted in a density ratio of 4.2 persons per square kilometer. Over the past decade, Mallala demonstrated resilient growth patterns with a compound annual growth rate of 1.0%, outperforming the SA4 region. Population growth for the area was primarily driven by interstate migration, contributing approximately 60.3% of overall population gains during recent periods.

However, all drivers including natural growth and overseas migration were positive factors. AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category were used, released in 2023 and based on 2021 data, with adjustments made using a method of weighted aggregation of population growth from LGA to SA2 levels. Anticipating future population dynamics, an above median population growth of non-metropolitan areas nationally was projected, with the area expected to grow by 629 persons to 2041 based on the latest annual ERP population numbers, reflecting a total increase of 15.9% over the 17 years.

Residential development activity is slightly higher than average within Mallala when compared nationally

Mallala has seen approximately 23 dwellings granted development approval each year. Over the past five financial years, from FY-21 to FY-25, a total of 118 homes were approved, with an additional 9 approved so far in FY-26. On average, about 1.7 people have moved to the area annually for each dwelling built during these five years.

This balance between supply and demand has resulted in stable market conditions. The average expected construction cost value of new dwellings is $190,000, which is below regional levels, indicating more affordable housing options for buyers. In terms of commercial development, Mallala has registered $10.9 million in approvals this financial year, demonstrating moderate levels of activity.

Compared to the rest of South Australia, Mallala has experienced slightly higher development rates, with 14.0% above the regional average per person over the past five years. This has maintained good buyer choice while supporting existing property values. All recent building activity in Mallala consists of standalone homes, preserving the area's traditional low-density character and focusing on family homes that appeal to those seeking space. The location currently has approximately 189 people per dwelling approval, indicating an expanding market. According to the latest AreaSearch quarterly estimate, Mallala is projected to grow by 569 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing favorable conditions for buyers and potentially supporting population growth beyond current projections.
