Seabrook

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 February 2026, is approximately 4,977, indicating a rise of 25 individuals since the 2021 Census which reported 4,952 inhabitants. This increase was inferred from ABS' estimated resident population of 4,963 in June 2024 and five additional validated addresses post-Census. The population density is 3,072 persons per square kilometer, placing Seabrook in the upper quartile nationally according to AreaSearch's assessments. Overseas migration accounted for roughly 64.4% of recent population growth. AreaSearch uses ABS/Geoscience Australia projections released in 2024 with a base year of 2022 for each SA2 area, and VIC State Government's Regional/LGA projections from 2023 adjusted to SA2 levels for areas without ABS data.

Future trends indicate significant growth by 2041, with Seabrook expected to expand by 1,569 persons, a 31.2% increase 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. Between financial years 2021 (FY-21) and 2025 (FY-25), 15 homes were approved, with no approvals recorded so far in FY-26.

The population decline in recent years suggests that the new supply has likely kept pace with demand, providing good choices for buyers. The average construction cost value of new homes is $262,000, 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 supply generally supports stronger demand and values for established properties. Development activity is also lower than national averages, reflecting market maturity and potential development constraints.

Recent development has consisted entirely 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 location, indicating an established market. According to the latest AreaSearch quarterly estimate, Seabrook is expected to grow by 1,555 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.

In comparison, Greater Melbourne recorded employment growth of 3.0% and unemployment rising by 0.3 percentage points over the same period. Jobs and Skills Australia's national employment forecasts from May-25 project national employment growth of 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 simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
