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
Blackburn South has an estimated 11,087 residents, up from 10,939 at the 2021 Census — a change of 148 people, or 1.4%. That puts 3,080 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 investigations by AreaSearch, the resident count for Blackburn South stands at approximately 11,087 as of May 2026. This represents a growth of 148 individuals (1.4%) relative to the 2021 Census, which recorded 10,939 residents. This shift is calculated using the ABS estimated resident population of 11,072 from June 2025 alongside 42 validated new addresses registered after the Census. This population level yields a density of 3,079 persons per square kilometer, placing the suburb in the highest national quartile of analyzed areas. Recent population gains were almost entirely generated by overseas migration, which served as the exclusive driver of growth.
Projections from ABS and Geoscience Australia released in 2024 with a 2022 baseline are adopted for each SA2. For areas lacking this coverage, figures are derived from the 2023 VIC State Government Regional/LGA projections, adjusted via weighted aggregation of population expansion from LGA to SA2 tiers. Age cohort growth rates from these models are also applied to all locations for the period spanning 2032 to 2041. Future demographic forecasts point to a population rise slightly under the national median, with the locality projected to add 445 residents by 2041 based on the most recent annual ERP data, representing a total expansion of 3.9% over the 16 years.
Frequently Asked Questions - Population
224 new dwellings have been approved in Blackburn South over the past five years, an average of 44 a year. That is 4.0 approvals per 1,000 residents. Of the 37 dwellings approved in the latest reporting year, 73% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 33, broadly in line with that longer-run average. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.
Detail
An average of approximately 44 new residential approvals are registered annually in Blackburn South, totaling 224 approved dwellings over the 5 financial years from FY-21 to FY-25, and 31 during FY-26 so far. As the local population has contracted in recent years, this incoming supply has likely matched demand to provide buyers with ample choices, while new construction projects carry a mean value of $514,000, indicating that builders are targeting affluent buyers with high-end housing. Furthermore, commercial approvals reached $2.2 million this financial year, pointing to a development landscape dominated by residential projects.
Building activity in Blackburn South is constrained, tracking 53.0% below the per-capita average of Greater Melbourne. This limited construction volume typically supports demand and valuations for established properties. The pipeline of new projects consists of 73.0% detached houses and 27.0% medium and high-density options, maintaining the suburban character of the neighborhood through a focus on stand-alone homes that appeal to buyers wanting space. Averaging roughly 305 people for each approved dwelling, the suburb exhibits the hallmarks of a low-density residential community. Looking forward, the population of Blackburn South is projected to expand by 430 residents by 2041, based on the latest quarterly calculations from AreaSearch. Considering current building trends, the supply of new housing is anticipated to easily satisfy demand, providing favorable purchasing conditions and potentially supporting population increases above current forecasts.

5,717 residents of Blackburn South are employed, from a labour force of 6,066. Unemployment sits at 5.8%, with participation at 65.6%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.9% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 8,925, about 81% 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 labor force in Blackburn South is highly qualified, characterized by a substantial concentration of professional services, a jobless rate of 5.8%, and an estimated job growth rate of 1.5% over the past year. In March 2026, employed residents numbered 5,717, while the unemployment rate ran 1.0% higher than the Greater Melbourne benchmark of 4.8%, and the participation rate was slightly subdued at 65.6% compared to the metropolitan average of 70.2%. Census data indicates a high proportion of remote workers at 39.6%, though this figure may reflect the influence of Covid-19 lockdowns.
The primary employment sectors for local workers are health care & social assistance, professional & technical services, and education & training. The neighborhood displays a notable concentration in education & training, which employs residents at 1.3 times the metropolitan rate. On the other hand, construction is underrepresented, accounting for 7.9% of local employment compared to the regional benchmark of 9.7%. This mostly residential community seems to present few local employment options, as shown by comparing the count of Census working residents against the overall resident population. AreaSearch evaluations of SALM and ABS statistics indicate that during the year leading to March 2026, the volume of employed residents rose by 1.5% and the labor force expanded by 2.6%, causing the local unemployment rate to increase by 1.0 percentage points. Across Greater Melbourne, employment grew by 2.1% and the labor force expanded by 2.3%, resulting in a minor unemployment rise of 0.2 percentage points. National employment projections from Jobs and Skills Australia published in May-25 offer additional context on future demand in Blackburn South. These five and ten-year forecasts have been correlated with the local industry profile to estimate future trends. Nationally, employment is projected to grow by 6.6% over five years and 13.7% over ten years, though rates vary by sector. Applying these industry-level trends to the local workforce structure indicates that local employment would grow by 6.9% over five years and 14.0% over ten years, representing a basic weighted calculation for illustration that does not incorporate local population 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 — 42 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (10,939 at the 2021 Census → 11,087 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.
