Seaford (Vic.)

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 is 18,074 as of November 2025. This reflects a growth of 859 people since the 2021 Census, which reported a population of 17,215. The increase is inferred from ABS data showing an estimated resident population of 18,072 in June 2024 and 290 new addresses validated since the Census date. This results in a population density ratio of 1,454 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. Seaford's growth rate of 5.0% since the 2021 census exceeds both the SA4 region (3.1%) and the SA3 area, indicating it as a growth leader in the region. Natural growth contributed approximately 50.3% of 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 by this data, AreaSearch utilises VIC State Government's Regional/LGA projections released in 2023, adjusted using weighted aggregation methods to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. By 2041, Seaford is expected to increase by 1,893 persons based on the latest annual ERP population numbers, reflecting a total increase of 10.5% over the 17-year period.

Seaford has averaged approximately 84 new dwelling approvals annually. Over the past five financial years, from FY21 to FY25420 homes were approved, with an additional 37 approved in FY26 so far.

The new developments consist of 39.0% detached houses and 61.0% attached dwellings, reflecting a shift towards denser development that appeals to downsizers, investors, and entry-level buyers.
