Seabrook

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

Based on AreaSearch's analysis, Seabrook's population is around 4,977 as of Feb 2026. This reflects an increase of 25 people (0.5%) since the 2021 Census, which reported a population of 4,952 people. The change is inferred from the estimated resident population of 4,963 from the ABS as of June 2024 and an additional 5 validated new addresses since the Census date. This population level equates to a density ratio of 3,072 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Population growth for the area was primarily driven by overseas migration, which contributed approximately 64.4% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the VIC State Government's Regional/LGA projections released in 2023 with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group from these aggregations are also applied across all areas for years 2032 to 2041. As we examine future population trends, a significant population increase in the top quartile of national statistical areas is forecast, with the area expected to expand by 1,569 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 31.2% in total 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

Seabrook has averaged around 3 new dwelling approvals per year, with 15 homes approved over the past 5 financial years (between FY-21 and FY-25) and 1 so far in FY-26. With population declining over recent years, new supply has likely been keeping up with demand, offering good choice to buyers, while new homes are being built at an average value of $262,000—under regional levels—indicating more accessible housing choices for buyers.

Relative to Greater Melbourne, Seabrook has significantly less development activity (94.0% below regional average per person). This limited new supply generally supports stronger demand and values for established properties. This activity is likewise lower than nationally, reflecting market maturity and pointing to possible development constraints. Meanwhile, recent development has been entirely comprised 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 1,555 residents through to 2041 (from 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.

The employment environment in Seabrook shows above-average strength when compared nationally

Seabrook possesses a well-educated workforce, with professional services showing strong representation, an unemployment rate of only 3.8%, and 3.8% in estimated employment growth over the past year. As of December 2025, 2,867 residents are in work while the unemployment rate is 1.0% below Greater Melbourne's rate of 4.8%, and workforce participation is fairly standard (75.7% compared to Greater Melbourne's 71.3%). Based on Census responses, a high 32.9% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Leading employment industries among residents comprise retail trade, health care & social assistance, and professional & technical. The area demonstrates a particularly notable concentration in transport, postal & warehousing, with employment levels at 1.6 times the regional average. In contrast, health care & social assistance employs just 10.3% of local workers, below Greater Melbourne's 14.2%. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of Census working population vs resident population.

Based on AreaSearch analysis of SALM and ABS data, the 12-month period saw employment increasing by 3.8% alongside labour force increasing by 4.3%, causing the unemployment rate to rise by 0.5 percentage points. By comparison, Greater Melbourne recorded employment growth of 2.4%, labour force growth of 2.8%, with unemployment rising 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Seabrook. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Seabrook's employment mix suggests local employment should increase by 6.4% over five years and 13.1% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
