This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.
SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Sales Detail
Seabrook has an estimated 4,932 residents. The population has thinned by an average 1.2% a year over five years, slower than 93% of areas nationally. That puts 3,044 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
According to investigations by AreaSearch, the resident count of Seabrook stands at approximately 4,932 in May 2026. This represents a contraction of 20 individuals (0.4%) relative to the 2021 Census, when the population was recorded at 4,952 people. This shift is calculated using the June 2025 ABS estimated resident population of 4,932 alongside 5 validated new addresses identified since the Census. With these figures, the population density reaches 3,044 persons per square kilometer, placing the suburb in the highest quartile among nationwide areas analyzed by AreaSearch. Growth in the local population was mainly supported by incoming overseas migration, which accounted for roughly 68.4% of total population increases in recent times.
Projections from the ABS and Geoscience Australia, published in 2024 with a 2022 baseline, are adopted by AreaSearch for each SA2 unit. For SA2 territories where this dataset is unavailable, calculations utilize the 2023 Regional/LGA projections from the VIC State Government, adjusting the figures via a weighted combination of population increases from the LGA scale down to SA2 zones. The resulting age bracket growth rates are extended across all sectors for the period spanning 2032 to 2041. Future demographic trends indicate a major population surge in the highest quartile of national geographic regions, with expectations that the area will grow by 1,389 persons by 2041 based on the most recent annual ERP statistics, representing a 28.2% expansion overall across the 16 years.
Frequently Asked Questions - Population
Detail
Approvals for residential builds in Seabrook run at approximately 3 dwellings annually, yielding 15 homes approved over the preceding 5 financial years (from FY-21 to FY-25) and 2 during FY-26 to date. Given the shrinking population in recent times, this rate of building has been relatively sufficient, creating favorable conditions for buyers, with newly built structures averaging a value of $262,000—a figure below regional benchmarks—pointing to more economical housing alternatives for home buyers. Seabrook exhibits a significantly lower rate of residential construction compared to Greater Melbourne, sitting 94.0% below regional average per person.
This restricted flow of new housing typically supports demand and reinforces pricing for pre-existing properties. The level of building is also below the national average, reflecting a developed market and indicating potential regulatory or planning limits. Furthermore, all recent construction has consisted of standalone homes, preserving a suburban landscape centered on detached houses that appeal to buyers seeking extra space. The ratio of roughly 3098 people per dwelling approval indicates that Seabrook represents a highly established housing market. Projections indicate that Seabrook is set to add 1,389 residents by 2041, based on the latest quarterly calculations from AreaSearch. Should current construction volumes persist, the supply of homes might not satisfy population demands, which could heighten competition among buyers and underpin stronger increases in property prices.

2,851 residents of Seabrook are employed, from a labour force of 2,961. Unemployment sits at 3.7%, with participation at 75.7%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.4% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 3,646, about 74% of the resident population, so more people leave the area for work than travel in. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
A highly qualified labor force characterizes Seabrook, with a strong presence of professional services, a low unemployment rate of 3.7%, and an estimated 2.0% expansion in employment over the past year. In March 2026, there are 2,851 working residents, with the unemployment rate tracking at 1.1% below the 4.8% recorded for Greater Melbourne, while workforce participation is exceptionally high at 75.7% compared to Greater Melbourne's 70.2%. Census data reveals that a substantial 32.9% of the workforce operated from home, though this figure may have been influenced by COVID-19 lock restrictions.
The primary sectors employing local residents are retail trade, health care & social assistance, and professional & technical. The locality displays a clear specialization in transport, postal & warehousing, where the employment concentration is 1.6 times the regional rate. In contrast, health care & social assistance is underrepresented at 10.3% compared to the regional benchmark of 14.2%. Because the suburb is mostly residential, it appears to provide few local employment opportunities, as shown by the comparison of the Census working population against the resident population. An analysis of SALM and ABS statistics by AreaSearch shows that the 12-month timeframe saw a 2.0% increase in employment alongside a 1.9% rise in the labor force, which helped keep the unemployment rate steady. By comparison, Greater Melbourne recorded employment growth of 2.1% and labor force growth of 2.3%, resulting in a 0.2 percentage point increase. The national employment projections from Jobs and Skills Australia published in May-25 offer additional context on future demand trends in Seabrook. These five and ten-year projections have been applied to the local workforce structure to model potential growth. Nationally, employment is projected to grow by 6.6% over five years and 13.7% over ten years, though these rates vary widely by industry. Weighting these national sector projections against Seabrook's workforce mix indicates that local employment would expand by 6.4% over five years and 13.1% over ten years, representing a basic weighted projection for illustration that does not incorporate local population forecasts.

How the numbers are built
Population
The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 5 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (4,952 at the 2021 Census → 4,932 now). Annual growth rates are compound (CAGR), not simple averages.
Age profile
Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to May 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".
Property sales
Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.
Rents
Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.
Development & infrastructure
Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.
Employment & income
Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.
Education, transport & amenities
School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.
Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.
Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.
Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (213021345). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
