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

Seaford's population, as of August 2025, is approximately 18,083. This figure represents an increase of 868 people since the 2021 Census, which recorded a population of 17,215. The growth is inferred from ABS estimates showing an estimated resident population of 18,072 in June 2024 and an additional 294 validated new addresses since the Census date. This results in a population density of 1,454 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. Seaford's growth rate of 5.0% since the 2021 census exceeds both the SA4 region (3.2%) and the SA3 area, positioning it as a growth leader in the region. Natural growth contributed approximately 50.3% of overall population gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch employs VIC State Government's Regional/LGA projections released in 2023, adjusted using weighted aggregation from LGA to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Future population trends suggest a growth just below the national median, with an expected increase of 1,893 persons to 2041, reflecting a total increase of 10.4% over the 17-year period.

Recent residential development output has been above average within Seaford when compared nationally

Seaford averaged approximately 84 new dwelling approvals annually. Over the past five financial years, from FY21 to FY25420 homes were approved, with a further 23 approved in FY26 as of present. On average, 1.6 people moved to Seaford per year for each dwelling built during these years, suggesting balanced supply and demand conditions.

The average construction cost value of new homes was $500,000. In FY26, $40.0 million in commercial development approvals have been recorded, indicating robust commercial development activity. Compared to Greater Melbourne, Seaford has 54.0% more construction activity per capita, offering greater choice for buyers. New developments consist of 39.0% detached houses and 61.0% attached dwellings, reflecting a trend towards denser development that caters to downsizers, investors, and entry-level buyers. This shift from the area's existing housing composition (currently 74.0% houses) suggests decreasing developable sites and changing lifestyle preferences. Seaford has around 242 people per dwelling approval, indicating characteristics of a low-density area.

Population forecasts project an increase of 1,882 residents by 2041. Given current development patterns, new housing supply should meet demand, providing favorable conditions for buyers and potentially facilitating population growth beyond projections.

Conversely, professional & technical services employ only 6.5% of local workers, below Greater Melbourne's 10.1%. The predominantly residential area appears to offer limited local employment opportunities, as suggested by the difference between Census working population and resident population figures. Between June 2024 and June 2025, employment levels increased by 3.4%, while labour force grew by 4.6%, leading to an unemployment rate rise of 1.0 percentage points. In comparison, Greater Melbourne recorded employment growth of 3.5% and a 0.5 percentage point increase in unemployment during the same period. 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 Seaford's employment mix suggests local growth of approximately 6.4% over five years and 13.3% over ten years, though this is a simple weighted extrapolation for illustrative purposes only and does not account for localized population projections.
