Seabrook's population was 4,932 as of May 2026, a decrease of 20 people from the 2021 Census figure of 4,952. This change is inferred from ABS estimated resident population data of 4,932 in June 2025 and validation of five new addresses since the Census date.

Overseas migration contributed approximately 68.4% 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 by this data, AreaSearch employs 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. Future trends indicate a significant population increase in Seabrook, with an expected expansion of 1,389 persons by 2041 based on the latest annual ERP population numbers, reflecting a total increase of 28.2% over the 16-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 and 2025, inclusive, a total of fifteen homes were approved.

As of the current financial year 2026, one additional home has been approved. The population decline in recent years suggests that new supply has likely kept pace with demand, providing good options for buyers. The average construction cost value of new homes is $262,000, which is below regional levels, indicating more affordable housing choices for buyers. Compared to Greater Melbourne, Seabrook has significantly less development activity, being 94.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established properties.

The location's development activity is also lower than the national average, reflecting market maturity and possible development constraints. Recent development has been entirely comprised of standalone homes, maintaining Seabrook'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 the area, indicating an established market. According to AreaSearch's latest quarterly estimate, Seabrook is expected to grow by 1,389 residents through to the year 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.
