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.

Bacchus Marsh has an estimated 27,453 residents, up from 24,717 at the 2021 Census — a change of 2,736 people, or 11.1%. Growth has averaged 2.3% a year over five years. 1,329 new addresses have been validated here since Census night. Interstate and internal migration accounts for 41.5% of that increase. That puts 140 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 research conducted by AreaSearch, the resident count of Bacchus Marsh stands at approximately 27,453 as of Aug 2026. This represents an expansion of 2,736 residents (11.1%) relative to the 2021 Census tally of 24,717 people. Such growth is deduced by combining the ABS estimated resident population figure of 27,183 recorded as of June 2025 with 1,329 validated new addresses added following the Census count. With a population density of 139 persons per square kilometer, the locality offers generous living space per capita alongside considerable capacity for future expansion.
Outperforming both Victoria's 9.5% expansion and the nationwide benchmark, Bacchus Marsh's 11.1% post-2021 census surge positions it at the forefront of regional growth. Net interstate arrivals served as the primary growth catalyst, generating roughly 41.5% of recent population additions, complemented by positive contributions from natural increase and overseas migration. Projections published in 2024 by the ABS and Geoscience Australia using 2022 baseline figures form the foundation of AreaSearch's SA2 demographic modeling. For SA2 territories omitted from that release, AreaSearch incorporates 2023 VIC State Government Regional/LGA projections, applying a weighted aggregation methodology to scale LGA trajectories down to the SA2 tier. From 2032 to 2041, age-specific growth rates derived from these aggregations are utilized universally across districts. Looking forward, demographic forecasts indicate that the area will outperform the Australian statistical area median, gaining 5,195 persons through to 2041 relative to current annual ERP benchmarks, which translates to a cumulative 16-year expansion of 17.9%.
Frequently Asked Questions - Population
1,236 new dwellings have been approved in Bacchus Marsh over the past five years, an average of 247 a year. That places the area in the 93rd percentile for residential development activity nationally, about 9 approvals per 1,000 residents a year. Of the 247 dwellings approved in the latest reporting year, 84% were detached houses and the rest townhouses or apartments. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.
Detail
Residential planning approvals in Bacchus Marsh have averaged roughly 247 dwellings annually, totaling 1,236 building consents across the preceding 5 financial years (between FY-22 and FY-26). Net population gains have tracked at 2.4 new residents per year for every completed residence across the past 5 financial years (between FY-22 and FY-26), signaling solid underlying demand favorable to local real estate values. New dwelling construction costs average $389,000, aligning with wider regional averages. Furthermore, the current financial year has recorded $17.4 million in commercial building approvals, demonstrating consistent non-residential investment. Per capita building activity in Bacchus Marsh remains substantially subdued relative to Greater Melbourne, tracking 58.0% below regional average per person.
This constrained pace of additions tends to bolster property values and demand across the established dwelling stock. Low-density detached houses comprise 84.0% of approved residential construction while medium and high-density housing accounts for 16.0%, reinforcing the suburb's historical open-character lifestyle tailored to families desiring spacious living. Registering roughly 108 people per approval, Bacchus Marsh exhibits the traits of an expanding community. Projections indicate that Bacchus Marsh will absorb 4,924 additional inhabitants through to 2041 according to the most recent AreaSearch quarterly estimate. Current construction trajectories suggest that residential development will comfortably accommodate this expanding population base, maintaining supportive market conditions for purchasers and creating capacity for demographic growth to potentially surpass projected levels.

14,735 residents of Bacchus Marsh are employed, from a labour force of 15,407. Unemployment sits at 4.4%, with participation at 71.1%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.2% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 23,465, about 85% 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
Supported by a capable talent pool and strong representation across essential services sectors, Bacchus Marsh maintains an unemployment rate of 4.4% alongside an estimated 2.0% annual expansion in employment. Total employed residents numbered 14,735 as of March 2026, with local unemployment sitting 0.4% below Greater Melbourne's rate of 4.8% and labor force engagement closely aligning with Greater Melbourne's 70.1%. Census records show that 21.2% of workers carried out their duties from home, though pandemic-related movement restrictions during that period must be factored into interpretation. The primary employment sectors for local workers are construction, health care & social assistance, and education & training.
Construction represents a distinct area of workforce specialization, employing residents at 1.6 times the regional average. Conversely, professional & technical roles account for only 5.4% of resident jobs, well under the regional proportion of 10.1%. Comparison between resident employee totals and locally available positions indicates an undersupply of local employment opportunities within the immediate boundary. According to AreaSearch evaluations of ABS and SALM figures, local employment expanded by 2.0% over the 12 months to March 2026 while the labor pool grew by 1.9%, sustaining steady joblessness levels. Across the broader Greater Melbourne area over the same timeframe, employment climbed 2.1% and the labor force grew 2.3%, pushing the unemployment rate up by 0.2 percentage points. Longer-term employment trajectories can be gauged via the Mar-26 national industry forecasts released by Jobs and Skills Australia. Projecting across five-year and ten-year horizons against the local industry profile, these models outline upcoming workforce shifts. Nationwide employment is projected to expand by 6.6% over five years and 13.7% over ten years, with performance varying widely across different sectors. Calibrating these national industry trends to Bacchus Marsh's specific labor distribution suggests local employment growth of 6.2% over five years and 12.8% over ten years (note that this weighting exercise is purely illustrative and does not incorporate local 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 — 1,329 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (24,717 at the 2021 Census → 27,453 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.
Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (213041353). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
