Victorian Labor is facing fresh scrutiny over taxation after documents revealed more than $600,000 is being spent on consultancy work examining alternative ways to raise money for infrastructure needed to support new housing.
The work has become politically explosive because it emerged only days after the state’s auditor-general revealed a previously undisclosed levy had been built into public transport fares to help finance major transport projects including the Suburban Rail Loop.
Opposition Leader Jess Wilson says the consultancy contracts show the Carroll Labor government is considering further taxes and charges on property owners and developers ahead of the November state election.
The government strongly disputes that interpretation and says it has no plans to introduce a new property tax.
What the contracts do establish is that Infrastructure Victoria is examining how Victoria might change the mix of revenue used to pay for roads, schools, parks, public transport and other infrastructure required when thousands of additional homes are built.
One contract describes its purpose as assisting with research to estimate the amount of revenue needed to fund additional infrastructure generated by residents of new housing.
Another calls for analysis of alternative revenue mixes for Victorian state and local governments and comparison with the existing system of property-related taxes and charges.
The consultants are also expected to model how much different options could raise, examine their effects across different locations and development types and consider how Victoria could transition from existing mechanisms to an alternative system.
The project is expected to continue for about 12 months and be completed by March 2027.
Those terms leave open a broad range of potential options, but they do not mean a new tax has already been selected, approved or legislated.
Deputy Premier Gabrielle Williams was explicit when questioned about the reports at the weekend.
“There are no plans to introduce new property tax,” she said.
Pressed on whether the government could make wider changes to the tax system, Williams did not announce any new policy and said specialist expertise was sometimes required as governments investigated complex areas of policy.
A government spokesperson went further, dismissing opposition claims that Labor was plotting new taxes.
The distinction matters because the political argument surrounding the consultancy work is moving faster than the underlying policy process.
Victoria already uses a complicated network of developer charges, land-based taxes and infrastructure contributions. Governments and councils routinely require developers to contribute towards the facilities needed when development creates additional demand.
These mechanisms include Development Contributions Plans, Infrastructure Contributions Plans, public open-space contributions and the Growth Areas Infrastructure Contribution, known as GAIC.
GAIC applies to large parcels of land in Melbourne’s growth corridors, including parts of Casey, Cardinia, Hume, Melton, Mitchell, Whittlesea and Wyndham.
For 2026–27, GAIC rates range from about $122,000 to $145,000 per hectare depending on the category of land.
The money is used for infrastructure including public transport, schools, health facilities, emergency services, parks and community projects in rapidly expanding suburbs.
There are also Infrastructure Contributions Plans that can require developers to provide money, land or infrastructure directly.
For residential development in metropolitan greenfield growth areas, the standard infrastructure levy in 2026–27 totals about $275,000 per net developable hectare across community, recreation and transport components.
The government has already begun extending a more standardised contribution system into established Melbourne suburbs targeted for additional housing.
Under reforms announced for train and tram activity centres, developers are expected to contribute $11,350 for each new home, along with separate square-metre charges for commercial and industrial development.
Two-thirds of the money collected by councils under that model is intended to remain with local government for infrastructure, with one-third flowing to the state for state-level facilities.
The first activity centres are expected to begin applying the contribution system from 2027.
That public reform process provides important context to the latest consultancy controversy.
The idea of changing how new housing infrastructure is funded has not appeared suddenly or entirely behind closed doors.
Infrastructure Victoria’s long-term strategy, published in 2025, specifically recommended that the state simplify its infrastructure contribution schemes, expand them to cover different forms of housing development and better reflect differences in infrastructure cost between locations.
Its analysis found providing infrastructure for an additional home in a new outer suburb can cost up to $59,000 more than providing for an additional dwelling in an established suburb.
The Victorian government has separately stated that it intends to develop a statewide developer-contributions model.
The politically sensitive question is therefore not whether infrastructure contributions are being reviewed. That is already public.
The question raised by the new contracts is how wide the government’s search for alternative revenue will become and whether the final model could shift more of the cost onto homeowners, landowners, developers or other taxpayers.
Wilson says Victorians should be suspicious after the controversy surrounding the public transport levy.
That levy was exposed in an August report by the Victorian Auditor-General’s Office examining the funding and delivery of the Suburban Rail Loop.
The auditor found the government had approved an additional 1 per cent annual increase on public transport fares, above normal CPI increases, as part of a broader package of measures intended to help finance major transport infrastructure.
The charge began operating in January 2025.
Crucially, VAGO found that the government and transport authorities did not transparently disclose the levy to commuters when announcing fare increases in 2025 and 2026.
The auditor described the funding strategy as lacking transparency.
Treasury modelling estimated the rail improvement charge could generate about $8 billion in net present value terms through to 2062.
About 60 per cent of that amount, or roughly $4.8 billion, had been earmarked for the Suburban Rail Loop East project.
The charge was intended to compound year after year, meaning its impact on fares would become substantially larger over several decades.
VAGO also warned that higher public transport costs could encourage some commuters to switch to cars, potentially undermining part of the congestion-reduction benefit claimed for the rail project.
Ben Carroll, who became Premier this year and had previously served as public transport minister, announced that his government would abolish the levy after the auditor-general’s findings became public.
The decision removed one politically damaging revenue source but also revived questions about how Victoria will finance its enormous infrastructure program.
SRL East alone has a publicly reported cost of up to $34.5 billion.
VAGO said in June the state still faced a $5.5 billion gap in approved funding for the project and warned that further borrowing or new revenue measures could ultimately be necessary if existing funding sources failed to deliver as planned.
That backdrop explains why the newly revealed housing-infrastructure work has attracted immediate attention.
Victoria’s finances are already under considerable pressure, while residents face a heavier state and local tax burden than people elsewhere in Australia.
Australian Bureau of Statistics figures for 2024–25 show Victoria collected the equivalent of $6,605 per person in state and local government taxes, the highest rate among the states and territories.
New South Wales was next at $6,383 per person, while the national state-and-local average was $6,023.
Victoria’s state government alone collected about $39.6 billion in taxation revenue during that financial year, up 5.8 per cent from the previous year.
That makes any suggestion of another property-related charge politically difficult, particularly during an election campaign dominated by cost-of-living pressure, mortgage stress and housing affordability.
The opposition is attempting to turn that vulnerability into a question of trust.
Wilson argues the undisclosed transport charge means voters cannot be confident Labor will reveal the full extent of its tax plans before polling day.
She has promised a markedly different tax agenda if the Coalition wins government, including changes to land tax and stamp duty and the repeal of several Labor charges.
Labor says those promises would blow a multibillion-dollar hole in the state budget and force severe cuts elsewhere.
The government’s challenge is that housing infrastructure must still be paid for regardless of which party wins.
Victoria is attempting to build hundreds of thousands of additional homes while many local communities are already demanding more schools, roads, train services, hospitals, parks and community facilities.
If developers are charged too little, taxpayers may carry more of the cost.
If developers are charged too much, some projects can become financially unviable or the costs can ultimately be reflected in higher prices for new homes.
If existing homeowners are asked to contribute more through land or property taxes, governments risk worsening affordability for households already under pressure.
That trade-off is precisely why Infrastructure Victoria has argued for a simpler and more consistent system.
The current arrangement varies significantly depending on where development occurs and which contribution mechanism applies.
A statewide model could make the system easier to understand and give councils a more predictable source of money for infrastructure.
But the political consequences depend entirely on the design.
An alternative revenue mix could involve reforming existing contributions rather than introducing a wholly new tax. It could change who pays, when they pay and how revenue is shared between the state and councils.
It could also ultimately recommend no major change at all.
Until the consultancy work is completed and the government publishes a policy, claims that Victorians definitely face a new property tax go further than the available evidence.
What can be said with confidence is that the state is actively analysing alternatives to its existing property-related revenue system as it searches for a sustainable way to fund infrastructure around new housing.
Coming immediately after the hidden public transport levy controversy, that alone guarantees intense scrutiny.
For Carroll, the issue has become another test of his promise to put greater emphasis on transparency and responsible spending.
For the opposition, it offers an opportunity to make taxation and trust central themes of the November election.
And for Victorian homeowners and prospective buyers, the key question will not be whether consultants are studying the system, but what — if anything — the government ultimately asks them to pay.
