Statistical Area (SA2) Boundary Analysis

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.

DemographicsPopulation Growth in Mount Martha

Table Chart PROFILE FAQ

Mount Martha has an estimated 20,161 residents, up from 19,846 at the 2021 Census — a change of 315 people, or 1.6%. 102 new addresses have been validated here since Census night. That puts 667 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 population of Mount Martha stands at approximately 20,161 as of May 2026. This represents an expansion of 315 residents (1.6%) from the 2021 Census, which counted 19,846 people. This shift is calculated from the ABS estimated resident population of 20,161 in June 2025 combined with 102 validated new addresses registered after the Census. Such population numbers translate to a density of 667 persons per square kilometer, indicating low density and room for potential expansion. The 1.6% post-census growth rate of Mount Martha is within 0.4 percentage points of the broader SA3 region (2.0%), showing competitive expansion.

Population gains were primarily fueled by overseas migration, which acted as the main driver of growth in recent times. AreaSearch employs population projections from the ABS and Geoscience Australia published in 2024, using 2022 as the baseline. For SA2 areas excluded from this dataset, projections are derived from the 2023 VIC State Government Regional/LGA releases, adjusted using a weighted aggregation methodology to map growth from LGA down to SA2 boundaries. Age group growth rates from these aggregations are also applied for the period spanning 2032 to 2041. Looking at future demographics, the locality is projected to experience population growth above the national median, increasing by 3,097 residents by 2041 based on recent annual ERP data, which represents an overall rise of 15.4% over the 16 years.

Residential SupplyHousing Development & Building Approvals in Mount Martha

Table Chart PROFILE FAQ

339 new dwellings have been approved in Mount Martha over the past five years, an average of 67 a year. That is 3.4 approvals per 1,000 residents. Of the 55 dwellings approved in the latest reporting year, 73% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 49, well below 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

Mount Martha has recorded approximately 67 residential building approvals each year, summing to 339 dwellings over the preceding 5 financial years. In the current FY-26 period, 45 approvals have been documented so far. With an average of just 0.2 additional residents per year for every new home constructed over the 5 financial years from FY-21 to FY-25, construction activity is keeping pace with or running ahead of demand. This provides purchasers with more choice and creates conditions for population gains that may outpace current forecasts, with new homes averaging a build value of $803,000, showing that developers are targeting the high-end market with premium properties.

Furthermore, commercial approvals have reached $10.1 million this financial year, pointing to steady business investment. Compared to Greater Melbourne, Mount Martha exhibits roughly 65% of the per capita construction volume, placing it in the 49th percentile of areas evaluated nationwide, which suggests limited choice for purchasers and supports demand for existing homes. This level of building is also below the national average, reflecting the mature character of the suburb and pointing to possible planning restrictions. New residential builds comprise 73.0% detached houses and 27.0% semi-detached properties or apartments, maintaining the low-density profile of the suburb and appealing to buyers seeking space. The ratio of 385 people per approved dwelling highlights the quiet, low-scale nature of local development. Looking forward, Mount Martha is projected to add 3,097 inhabitants by 2041 according to the most recent quarterly estimate from AreaSearch. If building activity remains at its current pace, housing supply could fall short of population growth, which is likely to increase buyer competition and support price growth.

Is the Mount Martha SA2 keeping up with housing demand?
With the population expected to increase by 3,097 people by 2041, around 1,549 new dwellings will be necessary.

Application search is not available in Victoria. AreaSearch holds 309 applications for Mount Martha, but they are a record of past activity rather than a current register. Victoria has no state-wide planning portal and its council coverage is uneven, so we have switched the search off here rather than return partial answers. We are currently investigating a solution. No credits are charged for Victorian applications, and building approvals from the ABS and the major projects we track are unaffected.

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 — 102 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (19,846 at the 2021 Census → 20,161 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.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (214021382). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the Mount Martha SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this Mount Martha 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 Mount Martha 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 (Jun 2026), property sales & rents (Aug 2026), infrastructure projects (Jun 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to May 2026), age profile (to May 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.
