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.

Detail
According to research conducted by AreaSearch, the resident count in Rockbank - Mount Cottrell stands at approximately 39,743 as of Aug 2026. This represents an expansion of 22,190 people (126.4%) compared to the 2021 Census, when 17,553 people were counted. This figure is derived from the ABS estimated resident population of 37,532 recorded as of June 2025 alongside 7,528 validated new addresses confirmed following the Census. The local population density works out to 316 persons per square kilometer, indicating generous space per resident and substantial scope for additional building. Surpassing both Victoria (9.5%) and nationwide figures, Rockbank - Mount Cottrell's 126.4% surge since the 2021 census positions it at the forefront of regional expansion.
Net interstate migration served as the primary catalyst, delivering around 78.1% of recent population gains, though overseas arrivals and natural increase also provided positive contributions. AreaSearch incorporates ABS/Geoscience Australia projections for SA2 locations published in 2024 (using 2022 as baseline data). For locations not covered by this series, AreaSearch applies the VIC State Government's Regional/LGA projections from 2023, utilizing a weighted aggregation model to translate LGA growth to SA2 boundaries. Age cohort growth rates derived from these models are also applied across every locality for the 2032 to 2041 period. Looking ahead, the locality is forecast to experience remarkable expansion placing it within the top 10 percent of statistical areas across the nation, adding 55,146 persons to 2041 according to the most recent annual ERP statistics, which equates to an overall gain of 129.0% across the 16 years.

14,925 residents of Rockbank - Mount Cottrell are employed, from a labour force of 15,806. Unemployment sits at 5.6%, with participation at 58.1%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.6% 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 45,635, about 115% of the resident population, so the area draws in more workers than it sends out. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.

Over the same timeframe, Greater Melbourne experienced a 2.1% lift in employment, a 2.3% expansion in the labour pool, and a 0.2 percentage points increase in unemployment. Further forward-looking perspectives come from Jobs and Skills Australia's national employment projections from Mar-26, which examine five- and ten-year horizons against the local industry baseline.

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 — 7,528 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (17,553 at the 2021 Census → 39,743 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 (213041359). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
