Seabrook

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

As of November 2025, Seabrook's population is approximately 4,974, a 0.4% increase from the 2021 Census figure of 4,952 people. This increase is inferred from ABS' estimated resident population of 4,963 in June 2024 and an additional 5 validated new addresses since the Census date. The population density ratio is 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 recently. AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022.

For areas not covered, it utilises VIC State Government's Regional/LGA projections from 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, Seabrook's population is forecasted to increase by 1,569 persons, reflecting a total 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. Between the financial years 2021 (FY-21) and 2025 (FY-25), a total of 15 homes were approved, with no approvals recorded so far in FY-26.

The population has been declining recently, suggesting that new supply has likely met demand, providing good options for buyers. New homes have an average expected construction cost value of $262,000, which is below the regional level, indicating more affordable housing choices. Compared to Greater Melbourne, Seabrook has significantly less development activity, 94.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established properties. Development activity in Seabrook is also lower than the national average, suggesting 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. As of now, there are approximately 3083 people per dwelling approval in Seabrook, indicating an established market. According to the latest AreaSearch quarterly estimate, Seabrook is expected to grow by 1,558 residents by 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
