Suburb (SAL) Boundary Analysis

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.

Surpassing both the state benchmark of 9.5% and nationwide figures, the suburb of Rockbank's 46.7% expansion establishes it as a regional growth frontrunner. Net interstate migration served as the primary growth catalyst, generating roughly 85.0% of recent population additions, while natural increase and overseas migration also provided positive contributions. For individual SA2 locations, AreaSearch incorporates ABS/Geoscience Australia demographic projections published in 2024 using 2022 as the base year. In locations omitted from that release, AreaSearch applies the 2023 Victorian State Government Regional/LGA dataset, distributing growth from LGA to SA2 divisions via weighted aggregation methods.

Jobs & IndustryEmployment Trends in Rockbank

Table Chart PROFILE FAQ

1,521 residents of Rockbank are employed, from a labour force of 1,615. Unemployment sits at 5.9%, with participation at 73.3%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.5% nationally over five years. That reflects industry composition only and makes no allowance for local population growth, so in an area growing as fast as this one it understates the likely rise in local jobs. The working-day population is estimated at 3,248, about 86% 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

AreaSearch aggregations of local statistical data show that Rockbank maintains an educated workforce active across varied industries, alongside an unemployment rate of 5.9%. Total employed residents stood at 1,521 as of March 2026. The local unemployment rate sits 1.1% higher than the 4.8% recorded for Greater Melbourne, while labour force participation remains steady at 73.3%, compared to 70.1% across Greater Melbourne. Census records indicate that 21.8% of employed locals worked from home, a figure influenced by prevailing Covid-19 restrictions at the time. Resident employment is primarily concentrated across transport, postal & warehousing, health care & social assistance, as well as construction.

In particular, local specialization in transport, postal & warehousing is pronounced, capturing an employment share 2.8 times that of the broader region. Conversely, education & training accounts for only 5.1% of working locals, remaining underrepresented when compared against the 9.2% benchmark in Greater Melbourne. Comparing the Census resident worker total against the local working population highlights that this predominantly residential precinct offers relatively few job opportunities within its own boundaries. AreaSearch examination of ABS and SALM data across aggregated statistical areas shows that in the year to March 2026, Rockbank experienced a 12.0% contraction in its labour force and a 13.2% drop in employed persons, leading to a 1.3 percentage points increase in the jobless rate. In contrast, Greater Melbourne saw employment climb by 2.1%, the labour force rise by 2.3%, and unemployment edge up by 0.2 percentage points. Forward-looking workforce demand can be evaluated using national employment forecasts released by Jobs and Skills Australia as of Mar-26. Projected across five and ten-year horizons, these figures are mapped to the local industry base to model potential outcomes. Nationwide job growth is projected at 6.6% over five years and 13.7% over ten years, with performance varying widely by sector. Applying these sector-specific trajectories to the local industry distribution suggests that employment among Rockbank residents could expand by 6.5% over five years and 13.3% over ten years (note that this illustrative model relies solely on weighted industry extrapolation and excludes localized demographic 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 — 721 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,583 at the 2021 Census → 3,790 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 (SAL22186). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

How do Rockbank suburb boundaries differ from Statistical Areas?
This page uses Suburbs and Localities (SAL) boundaries (suburb-style geography). SAL represents commonly-known suburb names used in addresses, while Statistical Areas (SA2) are designed for census/statistical reporting. Even when sharing the same name, SAL and SA2 boundaries often cover different geographic areas with different populations.
Where does the data on this Rockbank page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Rockbank data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Aug 2026), property sales & rents (Sep 2026), infrastructure projects (Sep 2026) and services & amenities (Sep 2026). Built on a Census baseline but carrying newer measures on top: population (to Aug 2026), age profile (to Aug 2026), employment (to Mar 2026), income (to FY 2023), education (to Sep 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
