Seabrook

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

By May 2026, the population of the suburb of Seabrook is estimated at around 4,932, reflecting a decrease of 20 people since the 2021 Census which reported a population of 4,952. This estimate by AreaSearch follows examination of the latest ERP data release by the ABS in June 2025 and validation of five new addresses since the Census date. The population density is calculated at 3,044 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's projections for Seabrook are based on ABS/Geoscience Australia projections released in 2024 with a base year of 2022, and VIC State Government's Regional/LGA projections released in 2023 adjusted using weighted aggregation methods for areas not covered by the former data.

Growth rates by age group from these aggregations are applied across all areas for years 2032 to 2041. By 2041, a significant population increase is forecasted for Seabrook, with an expected expansion of 1,392 persons, reflecting a gain of 28.2% in total 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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Seabrook has experienced around 3 dwellings receiving development approval each year. An estimated 15 homes were approved over the past five financial years, between FY-21 and FY-25, with one more approved in FY-26 so far.

The population has been declining recently, suggesting that new supply has likely kept up with demand, providing good choice for buyers. New dwellings are developed at an average expected construction cost value of $389,000. 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 dwellings. Nationally, this is also below average, reflecting the area's maturity and possible planning constraints.

Recent development has been entirely comprised of detached dwellings, sustaining Seabrook's suburban identity with a concentration of family homes suited to buyers seeking space. The location has approximately 1977 people per dwelling approval, indicating an established market. Population forecasts suggest Seabrook will gain 1,392 residents by 2041 (from the latest AreaSearch quarterly estimate). At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.

By comparison, Greater Melbourne recorded employment growth of 2.4% and unemployment rise of 0.3 percentage points. National employment forecasts from Jobs and Skills Australia (May-25) project a 6.6% increase over five years and 13.7% over ten years. Applying these projections to Seabrook's industry 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.
