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 Nov 2025, the population of Seabrook is estimated at around 4,974 people. This figure reflects an increase of 22 individuals since the 2021 Census, which recorded a population of 4,952. The current estimate is inferred from AreaSearch's validation of new addresses and examination of the latest ERP data release by the ABS in June 2024, indicating a resident population of 4,963 with an additional 5 validated new addresses since the Census date. This results in a population density ratio of approximately 3,070 persons per square kilometer, placing Seabrook in the upper quartile relative to other locations assessed by AreaSearch. Overseas migration contributed around 64.0% of overall population gains during recent periods for the suburb.

AreaSearch is adopting 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 from 2023, adjusted using weighted aggregation methods to population growth from LGA to SA2 levels. Growth rates by age group are applied across all areas for the years 2032 to 2041. Based on these demographic trends and projections, Seabrook is forecasted to experience significant population growth in the top quartile of Australian statistical areas. By 2041, the suburb's population is expected to increase by 1,569 persons, reflecting a total gain of approximately 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

AreaSearch analysis of ABS building approval numbers indicates that Seabrook has experienced around 3 dwellings receiving development approval each year. Approximately 15 homes have been approved over the past 5 financial years, from FY-21 to FY-25, with none approved so far in FY-26.

The population decline in recent years suggests that new supply has likely kept up with demand, offering good choice to buyers. New dwellings are developed at an average value of $389,000, which is below regional norms, reflecting more affordable housing options for purchasers. Compared to Greater Melbourne, Seabrook records markedly lower building activity, 94.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing homes. This trend is also lower than nationally, suggesting market maturity and possible development constraints.

Recent building activity consists entirely of detached houses, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. The location has approximately 1978 people per dwelling approval, demonstrating an established market. Future projections show Seabrook adding 1,558 residents by 2041, according to the latest AreaSearch quarterly estimate. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.

AreaSearch assessment positions Seabrook ahead of most Australian regions for employment performance

Seabrook's workforce is highly educated with significant representation in professional services. The unemployment rate was 3.6% as of June 2025, below the Greater Melbourne average of 4.6%.

Employment growth over the past year was estimated at 5.2%. Resident employment stood at 2,937 with a participation rate of 66.6%, slightly above Greater Melbourne's 64.1%. Key industries include retail trade, health care & social assistance, and professional & technical services. Transport, postal & warehousing is particularly strong, with an employment share 1.6 times the regional level.

However, health care & social assistance has a lower presence at 10.3% compared to the regional average of 14.2%. Employment opportunities locally appear limited based on Census data. Between June 2024 and June 2025, employment increased by 5.2%, labour force by 5.8%, leading to an unemployment rise of 0.6 percentage points. Greater Melbourne recorded similar trends with employment growth of 3.5% and unemployment rising by 0.5 percentage points. National employment forecasts from Jobs and Skills Australia, published in Sep-22, project national employment growth at 6.6% over five years and 13.7% over ten years. Applying these projections to Seabrook's employment mix suggests local employment should increase by 6.4% over five years and 13.1% over ten years, though this is a simplified extrapolation for illustrative purposes only and does not account for local population projections.
