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
Koroit has an estimated 2,285 residents, up from 2,184 at the 2021 Census — a change of 101 people, or 4.6%. Growth has averaged 1.2% a year over five years. Density is about 54 people per 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 regional ABS population statistics alongside 74 validated new addresses added following the Census, the suburb of Koroit is estimated to have a population of approximately 2,285 as of Aug 2026. This represents an addition of 101 people (4.6%) compared to the 2,184 residents recorded in the 2021 Census, aligning closely with an ERP-based resident population estimate of 2,282 derived from the ABS release in June 2025. The area offers spacious living conditions, featuring a density of 54 persons per square kilometer. Outpacing both the SA3 district and the broader SA4 region (0.5%), the suburb of Koroit emerged as an area growth leader with its 4.6% expansion since the 2021 census.
While natural increases and interstate migration also contributed positively, overseas migration served as the primary growth catalyst, generating roughly 48.0% of recent population gains. Projections for the suburb of Koroit rely on 2024 ABS/Geoscience Australia data using 2022 as a base year, supplemented where necessary by 2023 VIC State Government Regional/LGA projections converted to SA2 level via weighted population growth aggregation, with age-specific rates applied for 2032 to 2041. Applying this framework, demographic modelling indicates an overall contraction, projecting the population of the suburb of Koroit to fall by 658 persons by 2041. In contrast to the broader downward trend, specific senior demographics are expected to expand, most notably the 85 and over age group, which is projected to increase by 11 people.
Frequently Asked Questions - Population
145 new dwellings have been approved in Koroit over the past five years, an average of 29 a year. That is 8.7 approvals per 1,000 residents. Of the 20 dwellings approved in the latest reporting year, 95% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 16, well below that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.
Detail
Examining ABS building approval statistics across statistical boundaries, AreaSearch notes that Koroit averages roughly 29 approved residential dwellings per year, totaling approximately 145 homes across the past 5 financial years (between FY-21 and FY-25), with 16 approvals recorded to date in FY-25. Demonstrating balanced market fundamentals, an average of 1.4 incoming residents per year has corresponded to each approved dwelling over the past 5 financial years (between FY-21 and FY-25). Furthermore, newly approved residences carry an average estimated construction cost of $695,000, signaling residential building activity concentrated in the higher-end market.
Reinforcing the predominantly residential orientation of the area, commercial development approvals reached $5.1 million this financial year. Residential building volumes in Koroit sit 42.0% above regional average per person over the 5 year period compared to Rest of Vic., providing solid choices for purchasers and supporting local demand despite a recent deceleration in planning activity. Construction trends overwhelmingly favor standalone housing, with detached dwellings representing 95.0% and attached dwellings making up 5.0%, reinforcing the area's spacious, family-focused character. Low-density planning patterns are further highlighted by a ratio of roughly 152 people per dwelling approval. Given that demographic forecasts point toward flat or contracting resident numbers, home seekers in Koroit are likely to experience easing competition and lower housing demand pressures.

1,129 residents of Koroit are employed, from a labour force of 1,139. Unemployment sits at 0.9%, with participation at 60.4%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.0% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 1,783, about 78% 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
Workforce data aggregated across statistical areas highlights a capable local labour pool with solid representation across key public services and an unemployment rate of only 0.9%. Total employed residents stood at 1,129 as of March 2026, with local unemployment sitting 2.8% lower than the 3.7% recorded across Regional Vic., alongside workforce participation tracking near the regional mark of 61.1%. Remote work was relatively uncommon according to Census findings, with just 11.1% of workers based at home, though broader Covid-19 restrictions during that period may have influenced this outcome. Local employment is concentrated predominantly within health care & social assistance, retail trade, and construction.
Retail trade represents a notable strength in the area, engaging 1.3 times the regional proportion of workers. In contrast, professional & technical roles account for a modest 2.9% share of local employment, well below the 4.7% observed across the wider region. An imbalance between local resident workers and the count of jobs captured in Census data indicates that locally situated employment opportunities remain limited. An examination of combined SALM and ABS figures over the past 12-month period reveals that Koroit experienced a 5.6% drop in its labour force and a 5.7% contraction in employment, while the unemployment rate remained virtually unchanged. Over the identical timeframe across Regional Vic., total employment slipped 0.1%, the workforce shrank 0.3%, and unemployment declined by 0.2 percentage points. Looking ahead, national forecasts from Jobs and Skills Australia as of Mar-26 project employment to grow by 6.6% over five years and 13.7% over ten years across Australia, though trajectory varies across specific sectors. Applying these sector-level expectations to the local workforce structure indicates that employment in Koroit could expand by 6.0% over five years and 12.9% over ten years, based purely on proportional industry weighting without local demographic adjustments.

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 — 74 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,184 at the 2021 Census → 2,285 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.
