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

As of November 2025, the estimated population of Seaview Downs is around 2,801, reflecting an increase of 83 people since the 2021 Census which reported a population of 2,718. This growth, equivalent to a 3.1% increase, is inferred from AreaSearch's resident population estimate of 2,797 based on the latest ERP data release by ABS in June 2024 and two additional validated new addresses since the Census date. This results in a population density ratio of 1,228 persons per square kilometer, above the national average assessed by AreaSearch. Seaview Downs' growth rate of 3.1% positions it within 2.3 percentage points of its SA4 region's growth rate of 5.4%, indicating competitive growth fundamentals. Overseas migration contributed approximately 65.0% of overall population gains during recent periods, driving primary growth in the suburb. AreaSearch adopts 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, AreaSearch uses the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, adjusted using a method of weighted aggregation of population growth from LGA to SA2 levels. Future demographic trends indicate that Seaview Downs is expected to increase its population by approximately 203 persons to reach a total of around 3,004 by 2041. This projected increase reflects an 8.0% growth 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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Seaview Downs averaged around 9 new dwelling approvals each year over the past five financial years, totalling an estimated 45 homes. So far in FY-26, 3 approvals have been recorded. Over these five years, there has been an average of 2.6 new residents per year for each dwelling, reflecting robust demand that underpins property values. New homes are being built at an average expected construction cost value of $475,000, somewhat higher than regional norms, indicating quality-focused development.

In FY-26, $17.2 million in commercial approvals have been registered, demonstrating moderate levels of commercial development. Relative to Greater Adelaide, Seaview Downs has significantly less development activity, 54.0% below the regional average per person. This scarcity typically strengthens demand and prices for existing properties, also under the national average, indicating the area's established nature and suggesting potential planning limitations. New construction has been completely comprised of standalone homes, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. With around 400 people per dwelling approval, Seaview Downs shows a developed market.

Future projections show Seaview Downs adding 224 residents by 2041, from the latest AreaSearch quarterly estimate. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

AreaSearch assessment positions Seaview Downs ahead of most Australian regions for employment performance

Seaview Downs has a skilled workforce with prominent representation in essential services sectors. The unemployment rate was 3.2% as of an unspecified past year, with estimated employment growth at 1.9%.

As of June 2025, 1,481 residents were employed, and the unemployment rate was 0.8% lower than Greater Adelaide's rate of 4.0%. Workforce participation in Seaview Downs was 64.4%, compared to Greater Adelaide's 61.7%. Employment is concentrated in health care & social assistance, construction, and retail trade, with notably high levels in construction at 1.4 times the regional average. Manufacturing, however, shows lower representation at 4.9% versus the regional average of 7.0%.

The area may offer limited local employment opportunities, as indicated by Census data comparing working population to resident population. In the year ending Sep-22, employment increased by 1.9%, while labour force grew by 2.4%, leading to a rise in unemployment rate of 0.5 percentage points. National employment forecasts from Jobs and Skills Australia project growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Seaview Downs's 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.
