Seaview Downs

Seaview Downs is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Based on ABS population updates and AreaSearch validations, as of Nov 2025, Seaview Downs' estimated population is around 2923. This reflects an increase of 205 people since the 2021 Census, which reported a population of 2718. The change was inferred from AreaSearch's resident population estimate of 2909 following examination of ABS's latest ERP data release (June 2024) and two additional validated new addresses since the Census date. This level of population results in a density ratio of 1282 persons per square kilometer, above national averages assessed by AreaSearch. Seaview Downs' growth rate of 7.5% since the 2021 Census exceeded the SA4 region's average of 7.3%. Overseas migration contributed approximately 65.0% of overall population gains during recent periods.

For projections, AreaSearch adopts ABS/Geoscience Australia figures released in 2024 with a base year of 2022 for each SA2 area. For areas not covered and years post-2032, SA State Government's Regional/LGA projections by age category are used, adjusted employing weighted aggregation methods from LGA to SA2 levels. Future population trends indicate an increase just below the median statistical area across the nation, with Seaview Downs expected to increase by 207 persons to reach a total of 3130 by 2041, reflecting a 3.6% overall increase over the 17-year period.

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

AreaSearch analysis of ABS building approval numbers shows Seaview Downs averaged around 14 new dwelling approvals each year over the past five financial years, totalling an estimated 71 homes. As of FY-26, 20 approvals have been recorded. This averages out to approximately 1.6 new residents per year per dwelling constructed between FY-21 and FY-25. New properties are constructed at an average value of $475,000, indicating a focus on the premium segment with upmarket properties.

In FY-26, $857,000 in commercial approvals have been registered, reflecting the area's residential nature. Compared to Greater Adelaide, Seaview Downs has around three-quarters the rate of new dwelling approvals per person and ranks among the 59th percentile nationally. Recent construction comprises 80.0% detached houses and 20.0% medium and high-density housing, preserving the area's suburban nature while responding to evolving lifestyle preferences and housing affordability needs. The location has approximately 255 people per dwelling approval, indicating room for growth.

According to the latest AreaSearch quarterly estimate, Seaview Downs is expected to grow by 106 residents through to 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Employment conditions in Seaview Downs demonstrate strong performance, ranking among the top 35% of areas assessed nationally

Seaview Downs has a skilled workforce with significant representation in essential services sectors. Its unemployment rate was 3.1% as of September 2025, which is 0.9% lower than Greater Adelaide's rate of 3.9%.

Employment growth over the past year was estimated at 3.1%. Workforce participation stood at 64.4%, slightly higher than Greater Adelaide's 61.7%. Key employment sectors include health care & social assistance, construction, and retail trade. Construction particularly stands out with employment levels at 1.4 times the regional average.

Conversely, manufacturing shows lower representation at 4.9% compared to the regional average of 7.0%. The area's predominantly residential nature suggests limited local employment opportunities, as indicated by the difference between Census working population and resident population numbers. Over a 12-month period ending in September 2025, employment increased by 3.1%, while labour force grew by 3.3%, resulting in a slight rise in unemployment rate of 0.2 percentage points. In comparison, Greater Adelaide saw employment grow by 3.0% and labour force expand by 2.9%, with a decrease in unemployment rate of 0.1 percentage points. State-level data from November 25, 2025 shows South Australia's employment grew by 1.19% year-on-year, adding 10,710 jobs, with an unemployment rate of 4.0%, outperforming the national average of 4.3%. Jobs and Skills Australia's national employment forecasts from May 2025 project overall employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Seaview Downs' employment mix suggests local employment should increase by 6.8% over five years and 14.0% over ten years, though this is a simple extrapolation for illustrative purposes and does not account for localized population projections.
