Chart Color Schemes
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 4,934 residents. The population has thinned by an average 1.2% a year over five years, slower than 93% of areas nationally. That puts 3,046 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
Demographic analysis by AreaSearch places the population of Seabrook at roughly 4,934 as of Aug 2026. This indicates a contraction of 18 people (0.4%) compared to the 4,952 people recorded at the 2021 Census. This adjustment stems from ABS estimated resident population figures showing 4,932 as of June 2025 alongside 7 validated new addresses identified following the Census. The suburb's density stands at 3,045 persons per square kilometer, positioning it within the upper quartile among assessed Australian regions. The primary catalyst for local demographic expansion has been overseas migration, accounting for roughly 68.4% of total population additions over recent intervals.
Population projections for each SA2 district are sourced from ABS/Geoscience Australia models published in 2024 using 2022 as a base year. Where SA2 coverage is absent, AreaSearch draws upon 2023 VIC State Government Regional/LGA projections, converting LGA data to SA2 levels via a weighted aggregation methodology. Age-specific growth distributions derived through this approach are likewise applied across 2032 to 2041. Long-term demographic modelling indicates upper-quartile national expansion for the locality, with projections indicating a gain of 1,388 persons by 2041 relative to latest annual ERP statistics, representing cumulative growth of 28.1% across the 16 years.
Frequently Asked Questions - Population
Detail
Over the preceding 5 financial years, residential building approvals in Seabrook totaled 12 homes, reflecting an annual average of about 2 new dwelling approvals. While recent demographic contraction has occurred, construction levels remain balanced relative to local demand, benefiting prospective purchasers, with typical new residential builds showing an average value of $471,000. Per capita building approvals in Seabrook sit substantially below regional activity, lagging Greater Melbourne by 94.0%. Such constrained residential addition generally bolsters pricing and competition across established housing stock, even with recent improvements in approval volumes. Volumes also trail national figures, underscoring an established urban footprint and possible planning restrictions.
Detached dwellings constitute all recent residential building activity, preserving the suburb's low-density profile focused on family residences. Showing roughly 1853 people per dwelling approval, the local real estate environment exhibits pronounced maturity. According to the most recent quarterly estimate from AreaSearch, Seabrook is projected to gain 1,386 residents by 2041. Should current construction volumes persist, housing supply could fall short of demographic expansion, likely driving upward pressure on property values and intensifying buyer competition.

2,851 residents of Seabrook are employed, from a labour force of 2,961. Unemployment sits at 3.7%, with participation at 75.2%. 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 3,648, 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
The local labour market is characterized by strong educational attainment, high participation within professional services, an unemployment rate of merely 3.7%, and an estimated employment growth rate of 2.0% over the past year. Employed locals numbered 2,851 as of March 2026, while the jobless rate sits 1.1% beneath the Greater Melbourne figure of 4.8%. Furthermore, the local participation rate reaches 75.2%, outpacing the metropolitan benchmark of 70.1%. At the Census, remote work was recorded by 32.9% of residents, a metric potentially shaped by prevailing Covid-19 pandemic restrictions. Key employment sectors among residents include retail trade, professional & technical, and health care & social assistance.
Transport, postal & warehousing exhibits marked local concentration, with worker representation tracking at 1.6 times the metropolitan average. Conversely, health care & social assistance engages only 10.3% of the resident workforce, trailing the Greater Melbourne mark of 14.2%. Comparing resident workers to the local working population at the Census indicates that this largely residential enclave provides relatively few internal employment positions. AreaSearch assessment of ABS and SALM figures indicates that during the year to March 2026, local employment rose by 2.0% alongside a 1.9% increase in the labour force, keeping joblessness relatively unchanged. Across Greater Melbourne over the same timeframe, employment expanded by 2.1% and the labour force grew by 2.3%, accompanied by a 0.2 percentage point rise in unemployment. Looking ahead, Jobs and Skills Australia national forecasts from Mar-26 provide indicative insight into future employment demand. When these five-year (6.6% nationally) and ten-year (13.7% nationally) industry projections are weighted against the local occupational distribution, Seabrook is estimated to achieve employment growth of 6.4% across five years and 13.1% across ten years, noting that this simple industry extrapolation serves illustrative purposes and excludes local demographic 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 — 7 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (4,952 at the 2021 Census → 4,934 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 Aug 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.
