The map of a monopoly
"Competition" is meant to be the thing that makes privatisation work. There is none. In Sydney, one company controls the lot — and the concessions don't expire until today's toddlers are middle-aged.
| Sydney toll road | Transurban stake | Can keep tolling until |
|---|---|---|
| Hills M2 | 100% | 2048 |
| WestConnex (M4 & M5) | 50% | 2060 |
| Eastern Distributor | 75.1% | 2048 |
| Cross City Tunnel | 100% | 2035 |
| Lane Cove Tunnel | 100% | 2048 |
| Westlink M7 | 50% | 2048 |
| NorthConnex | 50% | 2048 |
In Melbourne, Transurban's CityLink concession was extended to 2045. In Brisbane, after a string of private operators went bankrupt (see below), Transurban ended up as the sole toll operator too. verified This is not a market. It is a private tax on movement, granted by governments, over the roads you already paid to build.

The price is rigged to rise — by contract
You might tolerate a toll that tracked inflation. These don't. The escalation is a one-way ratchet baked into the deed, and it's set at the greater of two numbers so it can never fall behind.
When inflation is low, the toll still climbs ~4%. When inflation is high, the toll climbs with it. You lose both ways. Transurban has told investors that more than 90% of its toll revenue escalates automatically like this — a business model engineered so the price to you only ever goes up, no negotiation required. verified per-road floors: company figures
Why "greater of CPI or 4%" is the tell A price that merely tracked costs would just use CPI. Choosing "CPI or 4%, whichever is higher" only makes sense if the goal is to guarantee real, above-inflation increases forever. That is a design decision, written into a contract you weren't allowed to read, that runs until 2060.
Sources: Transurban corporate overview (investor materials); Michael West Media — Transurban toll escalation. The mechanism (greater of CPI or ~4%) is well established; exact per-asset floors come from company investor materials rather than the confidential deeds, so treat the precise numbers as company-sourced.
$123 billion — the government's own number
How much does a private tax on movement add up to? NSW Treasury and Transport for NSW did the sum themselves, and the figure is staggering.
The number was so alarming that the government introduced a $60-a-week toll cap from 1 January 2024 for the roughly 720,000 drivers paying the most — a tacit admission that the tolling had become unbearable. Meanwhile Transurban's Australian toll revenue ran to about $3.28 billion in 2023-24 alone. verified $123bn is a projection to 2060
Sources: NSW Government — Sydney toll bill modelling & $60 weekly cap (13 Nov 2023); Transurban FY2023-24 results (Australian toll revenue ~$3.283bn). The $123bn / $64bn figures are official projections to 2060 (assuming ~2.5% long-run inflation and population growth), not a present-day cost — read them as modelling.
Who really owns the road you're paying for?
Here is the twist that makes the toll road the perfect emblem of this whole site. WestConnex isn't just owned by Transurban. When NSW sold 51% of it in 2018 for $9.3 billion, the buyers were Transurban (50%), Canada's pension giant CPPIB (20.5%), Abu Dhabi's Tawreed (9%) — and AustralianSuper, with 20.5%. verified
So a Sydney worker with AustralianSuper pays a toll — rising at the greater of CPI or 4% — into a road that their own compulsory retirement savings part-own, and hands Transurban an operating margin on the way past. You paid tax to build it, you pay a toll to drive it, and you pay a fund fee to own it. That loop gets its own page →

The bit that isn't a road at all
Toll roads are sold as transport. But once you notice the escalation clause, the concession length and the ownership, a toll road looks less like infrastructure and more like a 50-year, inflation-protected, government-guaranteed income stream — a bond that happens to have asphalt attached. That's exactly why pension funds and sovereign wealth funds queue up for them: not for the driving, for the rent. The public built the bond and then sold it.
