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 as of August 2025 is approximately 4,974, representing an increase of 22 people since the 2021 Census which reported a population of 4,952. This change is inferred from the 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 during recent periods. AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and VIC State Government's Regional/LGA projections released in 2023 adjusted using weighted aggregation for areas not covered by ABS data.

Future population trends forecast a significant increase in the top quartile of national statistical areas, with Seabrook expected to expand by 1,569 persons to 2041 based on latest 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. Development approval data is produced by the Australian Bureau of Statistics on a financial year basis, showing 15 homes over the past five financial years from FY2021 to FY2025, with zero so far in FY2026. The population has been declining recently, suggesting that new supply has likely kept pace with demand, providing good choices for buyers.

New properties are constructed at an average expected cost of $389,000, 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 new supply generally supports stronger demand and values for established properties. Development activity in Seabrook is also lower than nationally, 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.

The location has approximately 3083 people per dwelling approval, demonstrating an established market. Looking ahead, Seabrook is expected to grow by 1558 residents through to 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.
