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.

DemographicsPopulation Growth in Marmion

Table Chart PROFILE FAQ

Marmion has an estimated 2,634 residents, up from 2,390 at the 2021 Census — a change of 244 people, or 10.2%. Growth has averaged 1.4% a year over five years. Overseas migration accounts for 85.0% of that increase. That puts 2,290 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 AreaSearch evaluations combining broader ABS demographic updates with new addresses validated post-Census, the suburb of Marmion recorded an estimated population of approximately 2,634 as of Aug 2026. Compared to the 2,390 residents documented during the 2021 Census, this denotes an expansion of 244 people (10.2%). Such figures are derived from an AreaSearch resident count of 2,631 following the ABS ERP release in June 2025 alongside 6 validated new addresses identified after the Census. Consequently, population density stands at 2,290 persons per square kilometer, outpacing the national benchmark across AreaSearch study locations.

Moreover, the 10.2% rate of expansion since the 2021 census outstripped the 9.5% national figure, positioning the suburb of Marmion as a standout local growth area. Inflows from overseas migration served as the principal demographic catalyst, generating roughly 85.0% of recent population additions. Long-term modelling by AreaSearch incorporates 2024 ABS and Geoscience Australia SA2 projections calibrated against a 2022 base year. For locations lacking this coverage, as well as forward estimates beyond 2032, models draw upon age-cohort trajectories from the 2023 ABS Greater Capital Region release (utilising 2022 data). Demographic forecasts indicate that the suburb of Marmion will outpace median population growth across AreaSearch analytical areas, climbing by 337 persons to 2041 under aggregated SA2 projections and securing an overall expansion of 12.7% across the 16 years.

Residential SupplyHousing Development & Building Approvals in Marmion

Table Chart PROFILE FAQ

38 new dwellings have been approved in Marmion over the past five years, an average of 7 a year. That places the area in the 60th percentile for residential development activity nationally, about 3 approvals per 1,000 residents a year. Approvals are currently running at an annualised 6, broadly in line with 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

An evaluation of ABS building statistics by AreaSearch reveals that residential construction approvals in the area have averaged roughly 7 per annum, accumulating to 38 new residences across the preceding 5 financial years. Within FY-25 to date, 6 residential approvals have been granted. Between FY-21 and FY-25, new additions averaged 4.3 residents annually per completed dwelling, creating a supply-demand imbalance that heightens purchasing competition and exerts upward pressure on real estate values. At the same time, newly approved homes carry an average construction cost of $1,069,000, illustrating an emphasis by builders on upmarket residential developments.

In the non-residential sector, commercial project approvals reached $3.4 million during the ongoing financial year, reflecting modest commercial construction activity. Per capita residential development exceeded the Greater Perth benchmark by 19.0% over the 5 year period, offering incoming purchasers viable opportunities while maintaining healthy real estate demand. Nonetheless, this volume remains below wider nationwide averages, pointing to potential planning boundaries within an established suburb. Detached dwellings represented 57.0% of recent approvals while medium-to-high-density apartments and townhouses accounted for 43.0%, delivering varied dwelling formats ranging from traditional houses to cost-effective compact homes. This represents a noticeable shift from the existing built form of 83.0% detached houses, signaling tighter land constraints alongside changing buyer needs. The current ratio of approximately 192 people per dwelling approval demonstrates ongoing building capacity. Over the period ending in 2041, latest quarterly figures from AreaSearch anticipate an increase of 334 local inhabitants. If building volumes remain at their current pace, additions to residential stock could trail behind population increases, intensifying buyer rivalry and supporting continued capital value growth.

Across Greater Perth over the equivalent interval, employment widened by 2.0%, labour supply grew by 2.5%, and unemployment climbed 0.4 percentage points.

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 — 6 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,390 at the 2021 Census → 2,634 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 (SAL50905). 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 Marmion 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 Marmion 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 Marmion 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 (Aug 2026), infrastructure projects (May 2026) and services & amenities (Jul 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 Aug 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.
