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 4,932 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
Following an examination of ABS demographic data updates for the wider region and address updates verified by AreaSearch since the Census, the suburb of Seabrook had an estimated 4,932 residents as of May 2026. This represents a contraction of 20 people (0.4%) from the 4,952 individuals recorded in the 2021 Census. AreaSearch calculated this current resident figure of 4,932 by analyzing the ABS June 2025 release of ERP data alongside 5 validated new addresses added after the Census date. With this resident count, the density stands at 3,044 persons per square kilometer, placing the locality in the top quartile of Australian areas analyzed by AreaSearch.
In recent times, population expansion was chiefly supported by overseas arrivals, who accounted for approximately 64.0% of the overall demographic increase. For individual SA2 tracts, AreaSearch incorporates the 2024 projections from the ABS and Geoscience Australia, which use 2022 as their starting point. Where these are unavailable, projections released by the VIC State Government in 2023 are used, adjusting them via a weighted aggregation of population growth from local government areas to the SA2 level. Growth trajectories by age cohort derived from these aggregations are also projected forward for all districts from 2032 to 2041. Based on these combined SA2 projections, future demographic trends point to a substantial population rise within the top quartile of Australian regions, with the suburb of Seabrook projected to gain 1,392 residents by 2041, representing a total increase of 28.2% over the 16-year timeframe.
Frequently Asked Questions - Population
Detail
According to AreaSearch's evaluation of ABS building approval records mapped to statistical areas, the suburb of Seabrook has averaged about 3 residential approvals annually. This totals an estimated 15 residential approvals during the 5 financial years from FY-21 to FY-25, with an additional 2 recorded during FY-26 so far. Because the local population has contracted in recent years, the residential supply has remained sufficient for local demand, resulting in a balanced property market with ample choices for buyers, while newly approved homes show a mean construction value of $389,000. Compared to the broader Melbourne metropolitan region, the suburb of Seabrook shows very quiet building volumes, running 94.0% below the per-capita regional average.
Such restricted construction volumes typically help maintain demand and values for established housing stock. This pace is also lower than the national benchmark, indicating a mature residential market and potential zoning or land limits. Meanwhile, recent building approvals are made up entirely of single-family detached homes, preserving the established low-density feel of the area which caters to households wanting extra room. The suburb has approximately 1979 people for every single residential approval, highlighting a highly developed housing market. Long-term forecasts indicate the suburb of Seabrook will add 1,392 residents by 2041, based on the latest quarterly calculations by AreaSearch. If the building rate does not accelerate, new residential supply might fall short of the incoming population, which could intensify competition among property buyers and bolster home values.

2,851 residents of Seabrook are employed, from a labour force of 2,961. Unemployment sits at 3.7%, with participation at 75.8%. 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 3,645, 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 suburb of Seabrook possesses a highly qualified workforce with significant employment in professional services, an unemployment rate of just 3.7%, and an annual job growth estimate of 2.0%, according to AreaSearch's statistical area summaries. In March 2026, working residents numbered 2,851, and the local unemployment rate was 1.1% lower than the Melbourne metropolitan average of 4.8%. The labor participation rate is elevated at 75.8% compared to 70.2% across the wider Melbourne area. Census statistics show that 32.9% of local workers operated from home, though these figures were likely influenced by pandemic containment measures.
Resident jobs are heavily represented in retail trade, health care & social assistance, alongside professional & technical services. Transport, postal & warehousing shows a major concentration locally, with its share of the workforce reaching 1.6 times the regional average. Conversely, health care & social assistance is underrepresented, making up 10.3% of local employment compared to 14.2% across the metropolitan area. The highly residential character of the suburb of Seabrook means local employment options are limited, as shown by comparing the count of local jobs to working residents during the Census. An analysis of SALM and ABS statistics for the broader region shows that during the 12 months leading up to March 2026, local employment expanded by 2.0% and the labor force grew by 1.9%, leaving the unemployment rate virtually unchanged. In comparison, the Melbourne metropolitan area saw employment rise by 2.1%, the labor force expand by 2.3%, and the unemployment rate tick up by 0.2 percentage points. To understand future workforce demands in the suburb of Seabrook, national forecasts published by Jobs and Skills Australia in May-25 can be referenced. These five and ten-year national growth projections have been compared to the local industry mix to model future trends. While national employment is projected to grow by 6.6% over five years and 13.7% over ten years, the rates vary widely by industry. Applying these trends to the local industry distribution suggests employment for residents of the suburb of Seabrook would rise by 6.4% over five years and 13.1% over ten years, assuming a simple weighting profile without local population 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 — 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 (SAL22247). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
