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

Seabrook's population was approximately 4,974 as of November 2025. This figure represents an increase of 22 people from the 2021 Census count of 4,952, reflecting a growth rate of 0.4%. The increase is inferred from the estimated resident population of 4,963 in June 2024 and five new validated addresses since the Census date. This results in a population density ratio of 3,070 persons per square kilometer, placing Seabrook in the upper quartile relative to national locations assessed by AreaSearch. Overseas migration contributed approximately 64.4% of overall population gains during recent periods.

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, AreaSearch utilises the VIC State Government's Regional/LGA projections from 2023, adjusted using a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Future population trends forecast a significant increase in the top quartile of national statistical areas. Seabrook is expected to expand by 1,569 persons to 2041 based on the latest population numbers, reflecting an overall increase of 31.3% over the 17-year period.

The level of residential development activity in Seabrook is very low in comparison to the average area assessed nationally by AreaSearch

Seabrook has averaged approximately three new dwelling approvals per year. Over the past five financial years, from FY21 to FY25, 15 homes were approved, with none so far in FY26.

The population decline in recent years suggests that new supply has been keeping up with demand, providing good choices for buyers. The average construction cost value of new homes is $262,000, which is below regional levels, indicating more affordable housing options for buyers. Compared to Greater Melbourne, Seabrook has significantly less development activity, 94.0% below the regional average per person. This limited supply generally supports stronger demand and values for established properties. Development activity in Seabrook is also lower than national levels, reflecting market maturity and possible development constraints.

Recent development has consisted entirely of standalone homes, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. There are approximately 3083 people per dwelling approval, indicating an established market. By 2041, Seabrook is expected to grow by 1558 residents. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.

In comparison, Greater Melbourne saw employment growth of 3.5% and a 0.5 percentage point rise in unemployment. National employment forecasts from May 2025 project national growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Seabrook's employment mix suggests local growth of approximately 6.4% over five years and 13.1% over ten years, though these are illustrative extrapolations not accounting for local population changes.
