Statistical Area - sa2

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

Mannum's population, as of November 2025, is approximately 7,001, indicating a rise of 407 individuals (6.2%) since the 2021 Census which reported a population of 6,594. This increase is inferred from the estimated resident population of 6,932 in June 2024 and an additional 105 validated new addresses post-Census. This results in a density ratio of 2.1 persons per square kilometer. Over the past decade, Mannum has shown growth with a compound annual growth rate of 1.2%, outperforming its SA3 area. Interstate migration contributed approximately 82% to overall population gains recently. 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, SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted using weighted aggregation from LGA to SA2 levels. Future trends suggest lower quartile growth for Australia's non-metropolitan areas, with Mannum expected to increase by 79 persons to 2041, recording a total gain of 0.1% over the 17 years.

AreaSearch assessment of residential development activity positions Mannum among the top 25% of areas assessed nationwide

Mannum has received approximately 91 dwelling approvals per year over the past five financial years, totalling 459 homes. As of FY26, 42 approvals have been recorded. On average, 0.8 new residents settle annually for each dwelling constructed between FY21 and FY25. This rate suggests that new construction is meeting or exceeding demand, providing more options for buyers and potentially facilitating population growth beyond current projections.

The average expected construction cost of new properties is $308,000. In the current financial year, Mannum has registered $1.9 million in commercial approvals, reflecting its residential nature. Compared to the rest of South Australia, Mannum records 133% more development activity per capita, indicating ample choice for buyers and strong developer confidence in the area. Ninety-seven percent of new building activity involves standalone homes, with only 3% comprising medium or high-density housing, preserving the area's low-density character while attracting space-seeking buyers. With approximately 56 people per dwelling approval, Mannum indicates an expanding market.

Looking ahead, Mannum is projected to grow by nine residents by 2041, with current development patterns suggesting that new housing supply should readily meet demand and facilitate potential population growth beyond current projections.
