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 Feb 2026, Seabrook's population is estimated at around 4,977 people. This reflects an increase of 25 people since the 2021 Census, which reported a population of 4,952 people. The change was inferred from AreaSearch's resident population estimate of 4,963 in Jun 2024 and validation of five new addresses since the Census date. This results in a density ratio of 3,072 persons per square kilometer, placing Seabrook in the upper quartile relative to national locations assessed by AreaSearch. Overseas migration contributed approximately 64.0% of overall population gains during recent periods.

AreaSearch uses 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 from 2023 for areas not covered by the ABS data. Applying growth rates by age group across all areas for years 2032 to 2041, Seabrook is forecasted to have a significant population increase in the top quartile of Australian statistical areas, with an expected expansion of 1,569 persons by 2041, reflecting a gain of 31.2% over the 17 years.

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 allocated from statistical area data shows Seabrook has experienced around 3 dwellings receiving development approval each year. Approximately 15 homes were approved over the past 5 financial years, between FY21 and FY25, with none approved so far in FY26.

The average construction cost value of new dwellings is $389,000. Compared to Greater Melbourne, Seabrook records markedly lower building activity, at 94.0% below the regional average per person. Recent development has been entirely comprised of detached dwellings, sustaining the area's suburban identity with a concentration of family homes suited for buyers seeking space. The location has approximately 1978 people per dwelling approval, indicating an established market. Population forecasts estimate Seabrook will gain 1555 residents by 2041.

At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
