This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or 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
According to AreaSearch's evaluation of broader ABS population revisions and post-Census verified addresses, the suburb of Seabrook has an estimated resident count of roughly 4,934 as of Aug 2026. Relative to the 2021 Census tally of 4,952 people, this represents a reduction of 18 people (0.4%). The figure stems from an AreaSearch resident estimate of 4,932 following the ABS June 2025 ERP release, combined with 7 validated new addresses added following the Census. With a resulting density of 3,045 persons per square kilometer, the suburb places in the upper quartile across nationally evaluated areas.
Overseas arrivals served as the primary driver of demographic gains, generating roughly 64.0% of recent population increases. Population projections utilized by AreaSearch draw on 2024 ABS/Geoscience Australia datasets for each SA2 using 2022 as a base, supplemented where needed by 2023 Victorian State Government Regional/LGA figures adjusted through weighted aggregation to the SA2 level, with age-cohort rates applied across 2032 to 2041. Projections indicate the suburb of Seabrook is positioned within the top quartile of Australian statistical territories for forward expansion, with aggregated SA2 modelling pointing to an addition of 1,390 persons to 2041, representing a cumulative increase of 28.1% across the 16 years.
Frequently Asked Questions - Population
Detail
Examining ABS residential approval figures aggregated across statistical zones, AreaSearch identifies an annual average of roughly 3 new residential approvals in Seabrook, accumulating to approximately 15 homes over the previous 5 financial years, with 2 approvals logged to date in FY-25. Given the local population contraction, construction volumes have remained proportionally balanced, which offers favorable conditions for purchasers, while an average expected construction cost of $858,000 indicates developers are directing capital toward upper-tier, high-specification residential products. Residential building volumes in Seabrook track 94.0% below regional average per person compared against Greater Melbourne.
Although construction pace has picked up recently, such restricted new supply typically underpins demand and pricing across the existing dwelling stock. This subdued volume sits below the national benchmark as well, highlighting market maturation alongside prospective development limitations. Furthermore, recent building activity has consisted entirely of standalone houses, reinforcing the neighbourhood's established suburban character and supplying family-oriented dwellings for space-conscious buyers, with roughly 1649 people per dwelling approval reflecting an established residential environment. Demographic projections anticipate an influx of 1,388 residents into Seabrook through to 2041 relative to the latest quarterly estimate from AreaSearch. If prevailing construction rates persist, the addition of new housing may find it challenging to absorb population increases, potentially intensifying buyer competition and reinforcing upward movement in property values.

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 3,647, 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
Seabrook features a skilled local workforce marked by solid representation in professional services, an unemployment rate of merely 3.7%, and an annual employment increase estimated at 2.0% based on AreaSearch statistical aggregations. Employed residents numbered 2,851 as of March 2026, while the jobless rate sat 1.1% below Greater Melbourne's 4.8%, and participation reached an elevated 75.2% against Greater Melbourne's 70.1%. Census records indicated that 32.9% of workers operated from home, an outcome potentially influenced by Covid-19 restrictions. The primary employment sectors among local workers include retail trade, health care & social assistance, and professional & technical fields.
Transport, postal & warehousing shows pronounced local specialization, capturing an employment share 1.6 times the regional level. Conversely, health care & social assistance exhibits lower local representation, engaging only 10.3% of the resident workforce compared to 14.2% across Greater Melbourne. Comparing resident numbers against working counts from the Census suggests the largely residential suburb generates modest workplace opportunities within its own boundaries. AreaSearch's synthesis of SALM and ABS figures indicates that over the year to March 2026, local employment grew by 2.0% alongside a 1.9% expansion in the labour force, preserving relative stability in the unemployment rate; meanwhile, Greater Melbourne posted employment gains of 2.1%, workforce expansion of 2.3%, and an uptick in unemployment of 0.2 percentage points. Forward-looking insights from Jobs and Skills Australia's Mar-26 projections outline national employment increases of 6.6% over five years and 13.7% over ten years, though industry trajectories vary widely. Aligning these sectoral projections with Seabrook's workforce composition indicates projected local employment growth of 6.4% over five years and 13.1% over ten years (calculated as an illustrative weighted extrapolation that excludes localized demographic projections).

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.
