Sales Detail
Tyabb has an estimated 3,503 residents, up from 3,449 at the 2021 Census — a change of 54 people, or 1.6%. That puts 148 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
Tyabb's population is estimated at roughly 3,503 as of May 2026, according to AreaSearch's evaluation of ABS population updates for the wider region and recently validated addresses. Compared to the 3,449 residents recorded in the 2021 Census, this represents an addition of 54 people (1.6%). This adjustment is based on the resident count of 3,503, which AreaSearch calculated by analyzing the ABS Estimated Resident Population release from June 2025 alongside 39 new addresses verified since the census. The population density stands at 148 persons per square kilometer, indicating low density and potential for future expansion.
The post-census expansion rate of 1.6% trailing the SA3 region (2.0%) by 0.4 percentage points points to stable growth dynamics. Natural increase was the primary contributor to growth, accounting for approximately 52.0% of the total population gains in recent times. Projections from ABS and Geoscience Australia, issued in 2024 with a 2022 baseline, are utilized for each SA2 region. In instances where these projections are unavailable, calculations rely on the 2023 Victorian State Government Regional/LGA projections, adjusted by aggregating growth patterns from LGA to SA2 levels. Growth velocities across different age brackets derived from these calculations are also projected forward for the period from 2032 to 2041. Future demographic estimates suggest expansion above the median for Australian statistical areas, with projections indicating the region will add 383 residents by 2041, representing a overall increase of 10.9% over the 16 years.
Frequently Asked Questions - Population
54 new dwellings have been approved in Tyabb over the past five years, an average of 10 a year. That is 3.1 approvals per 1,000 residents. Approvals are currently running at an annualised 4, well below 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
Analysis of building approvals from the ABS indicates that Tyabb has averaged approximately 10 new residential approvals annually, amounting to 54 dwellings over the last 5 financial years. Thus far in FY-26, 4 approvals have been logged. In the context of a declining population in recent years, the incoming supply has likely matched demand, presenting buyers with reasonable options. The average value of these approved dwellings is $502,000, pointing to developer activity concentrated in the higher-end market. Additionally, commercial projects valued at $4.5 million were approved during this financial year, emphasizing that the locality remains predominantly residential.
Compared with Greater Melbourne, building activity per capita in Tyabb is about 60% of the metropolitan rate, placing it in the 8th percentile of all analyzed locations in Australia, which restricts buyer choice and bolsters demand for established homes. This level of activity is also below the national average, pointing to a mature market or constraints on new building projects. Standalone houses make up 67.0% of the new builds, while attached properties account for 33.0%, with townhouses and units expanding the available pricing options. This represents a significant shift from the current housing stock, which is 90.0% detached houses, reflecting a scarcity of development sites and changing buyer preferences. The ratio of 2332 people per dwelling approval highlights a quiet development landscape. Based on the most recent quarterly projections from AreaSearch, Tyabb is set to add 383 residents by 2041. Residential construction is currently keeping pace with this projected influx, although the growing population may lead to increased competition among buyers.

Frequently Asked Questions - Infrastructure
Martha Cove Marina Development
A $650 million premier waterfront residential master-planned estate and marina on the Mornington Peninsula. The development features approximately 1,150 residential dwellings, including luxury apartments like The Moorings and The Wheelhouse, alongside 600 marina berths and a 200-boat dry storage facility. Key infrastructure includes the $25 million Marine Drive underpass, a retail village centre, and the Martha's Table hospitality venue. While the core infrastructure and initial residential stages are complete, limited final apartment releases and secondary precinct upgrades, such as the Marine Enterprise Precinct, continue to be integrated into the established community.
Lifestyle Communities Tyabb - Residential Village (Refused)
Proposal by Lifestyle Communities for an over 50s land lease residential village (about 240-242 dwellings) at 59 Stuart Road, Tyabb. Mornington Peninsula Shire Council refused the permit in 2020; in 2021 VCAT upheld Council's refusal. The proponent has indicated it does not plan to appeal further. As of 2025 there is no approved permit and the project is not proceeding.
Somerville Townhouse Development
Boutique development of 9 properties consisting of 3 four-bedroom townhouses and 6 three-bedroom single storey units. All properties feature double garages with internal access and private low maintenance fully landscaped backyards. Located 350m from town centre and 100m from Somerville Primary School.

Mornington Battery Energy Storage System (MBESS)
A 240MW/650MWh utility-scale battery energy storage system (BESS) located in Tyabb, Victoria's Mornington Peninsula, scheduled for completion in 2025. The battery system will store enough electricity to power more than 40,000 homes. The project is developed by Valent Energy, with AusNet Services constructing the transmission infrastructure to connect to their Tyabb Terminal Station.
Stony Point Line Service Improvements
Planning and incremental upgrade program for the Stony Point rail corridor focused on improving reliability, level crossing renewals, accessibility, maintenance and future service improvements. While the wider Regional Rail Revival program has now been completed across Victoria, no standalone major capital upgrade for the Stony Point Line has entered construction. Recent works have primarily comprised maintenance, level crossing renewals and operational improvements supporting safer and more reliable services.
Tyabb-Somerville Recycled Water Scheme
The Tyabb-Somerville Recycled Water Scheme is a proposed recycled water network for agriculture, nurseries and public open space in the Tyabb, Somerville and Pearcedale region. South East Water investigated the scheme with Mornington Peninsula Shire Council and National Water Grid Authority support. The scheme would use Class A recycled water from the South Eastern Outfall near Baxter and deliver about 1,150 ML per year through a pump station, 10.9 km transfer main and 4.8 km of reticulation networks.The business case and feasibility work are complete, but the project is currently on hold and requires significant external funding plus updated planning, design and viability work before delivery.
Victorian Renewable Energy Terminal (VRET)
A dedicated assembly port at the Port of Hastings designed to support the import, storage, and assembly of offshore wind components for Victoria's 2GW offshore wind target. The project features a land-backed quay wall and significant reclamation at the Old Tyabb site. As of May 2026, the Victorian Government has committed AUD 124.5 million in the 2026/27 budget to advance the Environment Effects Statement (EES) process. The project is undergoing rigorous environmental assessment to protect Ramsar-listed wetlands, with public exhibition of the EES expected in 2026 following the finalization of scoping requirements.
1,893 residents of Tyabb are employed, from a labour force of 1,980. Unemployment sits at 4.4%, with participation at 67.0%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.2% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. 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 workforce is evenly distributed between professional and trade occupations, with construction employment showing particularly strong representation. The unemployment rate stands at 4.4%, and employment levels have remained stable over the past year. In March 2026, 1,893 residents were employed, and the local unemployment rate was 0.4% lower than the Greater Melbourne average of 4.8%. Workforce participation is slightly low at 67.0%, compared to 70.2% in Greater Melbourne. Census records show that 20.0% of the working population worked from home, though this figure was likely influenced by pandemic restrictions.
The primary sectors employing local residents are construction, health care & social assistance, and retail trade. Construction jobs are highly concentrated here, registering at 1.9 times the regional average. Conversely, professional & technical roles account for only 4.4% of employment, which is lower than the Greater Melbourne level of 10.1%. A comparison between local employment figures and Census population statistics suggests that a significant portion of residents travel outside the suburb for work. An analysis of SALM and ABS data shows that for the 12 months ending March 2026, employment grew by 0.2% while the labor force shrank by 0.3%, resulting in a 0.5 percentage point drop in the unemployment rate. This contrasted with Greater Melbourne, which recorded employment growth of 2.1%, labor force expansion of 2.3%, and a 0.2 percentage point increase in unemployment. National employment forecasts from May-25 by Jobs and Skills Australia provide context for future trends in Tyabb. These five and ten-year projections have been applied to the local workforce structure. While national employment is expected to grow by 6.6% over five years and 13.7% over ten years, the rates vary by industry. Extrapolating these patterns to the local employment structure suggests Tyabb could see employment growth of 6.2% over five years and 12.9% over ten years.

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 — 39 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (3,449 at the 2021 Census → 3,503 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 (SAL22594). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
