What would fix it

There are four reform areas with genuine potential to change the Roads Rort. Each is technically achievable. Each faces political obstacles. Some are already in partial operation.

The most impactful reform is also the most long-term: redesigning the terms under which future toll road concessions are awarded. Existing concessions (WestConnex to 2060, CityLink to 2035, NorthConnex to its current expiry) cannot be reduced without government compensating Transurban. But future concessions can be structured differently.

What it requires is a government that will act on it.

01Reform 1: Toll road concession redesign

Specific reforms that other jurisdictions use:

Revenue sharing: if traffic and toll revenue exceed the forecast on which the concession was based, government takes a share of the upside. Australia’s concessions capture the upside entirely for the private operator.

Mandatory price review: an independent tribunal reviews toll levels every five years and can order reductions if returns exceed an agreed threshold above the cost of capital. In France, toll increases on the historic motorway concessions are capped at 70 per cent of the previous year’s inflation, excluding new works the state requests ⁷.

Shorter concession terms: instead of 50-year concessions, 25-year terms with a mandatory renegotiation at the end. Shorter terms reduce the investor’s certainty of returns but also reduce the lock-in of users.

Competitive tender on lowest tolls: design tenders to reward bidders who commit to the lowest toll levels, not the highest upfront payment to government. The current model rewards maximising the sale price, which is achieved by maximising the net present value of future toll income.

The NSW Independent Toll Review examined some of these options; its final report, released in July 2024, recommended a state-owned entity, NSW Motorways, to take back control of tolls ¹⁰¹⁵. The government said it would consider the report and respond ¹⁰.

Correction, 7 October 2026. This section said the NSW Government review "(2023–25) is examining some of these options" and that implementation "has not yet followed", citing nothing; reference 15, an unspecified academic literature, pointed to The Conversation's home page. The Independent Toll Review released its final report in July 2024 ¹⁰¹⁵; the section now says so and what it recommended, and reference 15 now gives the final report itself.

Correction, 7 October 2026. This section said France's autoroute system "uses state-set annual toll increase limits that can be below CPI if the operator's return has been sufficient", citing the autoroutes.fr home page. The French government's answer to a parliamentary question ⁷ says increases on the historic concessions are capped at 70 per cent of the previous year's inflation, excluding new works; the section and key facts now say that, and reference 7 now gives that answer.

Correction, 8 October 2026. This section said, citing the French government's answer ⁷, that clauses limiting the concessionaires' profitability were added to the contracts. The answer confirms the 70 per cent cap on toll increases for the historic concessionaires but does not say that clauses limiting profitability were added, so those words are cut from this section, the correction above and reference 7. Reference 10 no longer names the Independent Toll Review's report Motorists First or says the release recommended uniform tolls and NSW Motorways: the release lists recommendations including declining distance-based tolls and IPART oversight of toll setting, and the proposal for NSW Motorways is in the final report itself ¹⁵.

02Reform 2: Toll relief: what exists, what’s needed

NSW has toll relief. The current scheme provides a 40 per cent rebate on NSW tolls above A$375 annual spending. It acknowledges the burden. It does not cap the toll or address the structural cause.

A more effective toll relief model would be means-tested, targeting households in the lower income quartiles who face the highest burden relative to income. The current scheme provides the same percentage rebate to a high-income earner using toll roads for convenience as to a low-income outer-suburban commuter with no alternative.

The NSW Government’s commitment to further toll relief is real. It is limited by the concession terms: the government cannot reduce tolls directly; it can only offset them through public funds. Every dollar of toll relief is a dollar the NSW Treasury pays to partly reverse the revenue stream flowing to Transurban.

Correction, 7 October 2026. The fact box said the government "recovered approximately 34 cents per dollar of public investment in WestConnex". The source, The Conversation in 2018 ¹⁸, calculated "a financial return of 34 cents for every dollar spent" for the sale of the first 51 per cent, before the 2021 sale; the box now says so and cites it.

03Reform 3: Fuel price cycle: FuelWatch for the east

Perth has had FuelWatch since 2001. It does not end the price cycle: Perth’s averaged about a week in 2025 ²⁰. What it does is fix each day’s price a day in advance ². Victoria adopted a version of it, a daily price cap set a day ahead, on 10 March 2026 ²¹²².

A FuelWatch mandate for NSW, Queensland and South Australia would require fuel retailers to submit their next-day prices to the government by a set time each day, with prices locked for 24 hours. Published prices would allow consumers to find the cheapest fuel in their area. It would not end the price cycle, which persists in Perth ²⁰, but it would stop prices rising during the day ².

The barrier is political: a FuelWatch rule needs a state government decision. Of the eastern states, Victoria has now legislated a version ²². The ACCC cannot mandate it.

A second fuel reform: fuel tax credit reform. The over A$9.5 billion annual subsidy that reimburses mining and agricultural companies for the excise on off-road fuel use could be reduced for highly profitable extractive industries. The revenue could fund household fuel excise relief. This is a federal policy lever that has not been pulled.

Correction, 7 October 2026. This section called FuelWatch "the fix for the fuel price cycle", said the weekly cycle "could not operate" under it, that the eastern states do not have it and that the ACCC "has noted the FuelWatch model approvingly". The ACCC reports that Perth has a price cycle too, averaging about a week in 2025 ²⁰; Victoria has capped each day's price a day ahead since 10 March 2026 ²¹²²; and no ACCC statement endorsing FuelWatch was found, so that sentence was removed. The section and key facts now say so. Reference 2, which pointed to the FuelWatch home page, now gives the WA regulator's description of the 24-hour rule ². Reference 6, which pointed to a gov.uk organisation page and carried no claim the article makes, is no longer relied on. The section also said fuel retailers "have opposed mandatory price disclosure in eastern states"; no source was found for that, and it was removed.

Correction, 8 October 2026. Reference 21 described Victoria's daily cap as set by retailers between 8:30am and 2pm; the Service Victoria page it points to gives no such window, so the reference now describes only what that page carries.

04Reform 4: Public ownership as the default

The Australian Government chose to build Western Sydney International Airport as a publicly owned facility. This is the logical alternative to privatisation: government builds, government owns, government sets prices with a commercial return target that does not need to include a private equity premium.

The analogy is instructive. Every argument made for privatising WestConnex (private capital, private efficiency, risk transfer) can be made against Western Sydney Airport. The government chose otherwise. The result: an airport that will be owned by taxpayers, whose pricing can be set transparently, whose returns go to public purposes rather than to Transurban security holders.

For toll roads: the key question for future projects is whether they should follow the WestConnex model (private concession, 50-year monopoly, inflation-linked tolls) or the Western Sydney Airport model (government-owned, commercial pricing, public returns). The NSW pipeline (Western Harbour Tunnel, Beaches Link, M6 Stage 1) has not resolved this question.

05What is already happening

Some reform is underway.

NSW toll road review: the Minns government commissioned an independent review. Findings released 2024 ¹⁰. Implementation ongoing.

Enhanced toll relief: NSW has expanded the scheme; further expansion promised.

Concession reform language: state government language around future concession design has shifted toward revenue sharing and shorter terms.

ACCC fuel monitoring extended: direction renewed for 5 years in December 2025. Monitoring continues, though without new enforcement powers.

What has not changed is the structural position: Transurban earned a 75 per cent EBITDA margin in FY25. Existing WestConnex concessions run to 2060 ¹⁷. Western Sydney motorists pay A$10.38 to use a road whose toll the concession lets rise each year by the greater of CPI or 4 per cent to December 2040, then by CPI until the concession ends ¹⁵.

Correction, 7 October 2026. This section said the WestConnex toll was "contractually guaranteed to rise for another 34 years"; the subtitle spoke of "40-year guarantees on rising returns" and the closing pullquote of "tolls rising for 40 more years". The WestConnex concessions run to 2060 ¹⁷, and the M4 concession lets tolls rise each year by the greater of CPI or 4 per cent to December 2040, then by CPI ¹⁵. That is a right to raise tolls, not a guarantee of returns, and 2060 is 34 years from 2026, not 40. All three now say the tolls can rise until 2060.

Update, 7 October 2026. Reference 10, which pointed to the Transport for NSW home page, now gives the NSW Government's announcement of the Independent Toll Review's final report ¹⁰.

Correction, 8 October 2026. This section cited the Linkt toll pricing page (reference 16) for the M4 toll escalation terms. The page as served carries no escalation terms, so the two statements now cite the Independent Toll Review's final report ¹⁵, which lists WestConnex, including the M4, at the greater of CPI or 4 per cent a year until 31 December 2040, then CPI. Reference 16 is no longer relied on.

06The political obstacle: same as every series

The political economy of toll road reform is the same as every other sector The Rort has covered. The benefits of reform are diffuse: millions of Australians paying slightly less for tolls and petrol. The costs of reform are concentrated: Transurban shareholders receiving smaller distributions, fuel retailers facing narrower margins.

Transurban has been described as a donor to both parties ²³; in 2024 it told a Queensland parliamentary committee that it does not make political donations in Australia ¹⁹. The concession model has bipartisan support. The industry that manages the infrastructure investment funds that own Transurban is the same industry that manages the retirement savings of the workers who pay the tolls. The financial system is designed to align their interests over the long term. The problem is the short term: the daily toll, the petrol price cycle, the annual toll rise.

The reform agenda is clear. FuelWatch in the east. Revenue-sharing concessions for future roads. Independent toll price review every five years. Government ownership as the default for new projects. Enhanced and targeted toll relief now, as bridge to structural reform.

What it requires is a government that will act on it.

Correction, 7 October 2026. This section said "Transurban is a political donor to both parties." The Greens reported in 2018 that Transurban made significant donations to both Labor and the Liberals ²³, but in August 2024 Transurban told a Queensland parliamentary committee that it does not make political donations in Australia ¹⁹. The sentence now gives both.

Correction, 8 October 2026. This section cited Green Left ¹³ for Transurban having donated to both the Liberal and Labor parties. The Green Left page does not mention donations, so that sentence is cut from reference 13. The two statements about donations now cite the Greens' release of 2 February 2018 ²³, which says Transurban made significant donations to both Labor and the Liberals.

07The Roads Rort: series complete

8 articles. The same road built with public money. Now a 75% margin private monopoly with tolls set to rise until 2060. The workers who built it pay to use it. Their super funds own it. Their politicians sold it.

If it’s a rort, we cover it.
