It was supposed to cost $2 billion. It now costs $42 billion. The ministers were getting monthly updates. Parliament wasn't told.
Here is the official timeline.
March 2017. Malcolm Turnbull announces Snowy 2.0 — a pumped-hydro expansion of the Snowy Mountains scheme. Cost estimate: $2 billion. Timeline: four years.
February 2019. The cost estimate is revised. The new range: $3.8 to $4.5 billion.
Six weeks later. The major works contract is signed. Value: $5.1 billion.
August 2023. Snowy Hydro undergoes a "reset." New cost: $12 billion — plus a $2.6 billion equity injection from the Commonwealth, plus a $4.5 billion taxpayer loan.
May 2026. The project now costs $42 billion.
That is twenty-one times the original estimate, in nine years.
The transmission lines required to connect Snowy 2.0 to the national grid are not included in that figure. They will cost billions more.
Who's Watching
Snowy Hydro is 100 per cent owned by the Commonwealth Government. This is not a private enterprise where shareholders absorb the blowout. Every dollar is public money.
The shareholder ministers — Energy Minister Chris Bowen and Finance Minister Katy Gallagher — received monthly variance reports. Monthly. That means updates on cost overruns and schedule slippage, regular as clockwork, delivered to the ministers responsible.
Parliament was not told.
You — whose money this is — were not told.
The government spent more than $600,000 in legal fees attempting to stop the release of its own cost reports. That's what it cost to keep the numbers quiet. Six hundred grand to suppress documents that belonged to the public.
The Personnel
The CEO of Snowy Hydro, Dennis Barnes, earns $2 million a year.
David Fredericks was the departmental secretary described in reporting on the project as "truly complicit in the disaster." He now sits on the Snowy Hydro board.
These career paths are worth noting.
What $42 Billion Could Buy
The 2023–24 federal budget allocated $5.7 billion for the National Disability Insurance Scheme. The entire Medicare Benefits Schedule costs roughly $30 billion a year. The federal infrastructure pipeline for roads and rail — across every state — is approximately $120 billion over a decade.
Snowy 2.0 alone, at current cost, is more than an entire year's Medicare, with change.
That's 100 per cent public money. One project.
The Mechanism
How does a $2 billion project become a $42 billion project?
Slowly, and then all at once. The pattern here is not unusual for large public infrastructure — but the scale is. Early estimates are optimistic because optimism gets projects approved. Contracts are signed before independent cost review is complete. Once work starts, stopping is more expensive than continuing. The overruns compound. The ministers keep getting the monthly reports. The press release doesn't follow.
The tunnelling at Snowy has faced significant geological challenges. Costs blew out on the main works contract. Inflation added pressure. The project kept going because the alternative — writing off billions already spent — was politically unthinkable.
So the bill got bigger instead.
The Timing Problem
This is not an ancient rort buried in budget documents. In 2026, this is live and ongoing. The project is not finished. There is no firm completion date that anyone will commit to publicly — the current target is 2028, give or take.
The transmission lines required to actually deliver the power from Snowy to the grid are a separate project, separately uncosted in the $42 billion figure.
If and when those costs become public, add them to the tally.
Who Benefits
Contractors, engineers, tunnelling companies, and consultants billing against what is now a $42 billion public project. The CEO on $2 million. David Fredericks on the board. The firms and individuals who continue to receive public money while the completion date keeps sliding.
Who Pays
Australian taxpayers. Energy users in New South Wales, the ACT, Victoria, South Australia, Queensland, and Tasmania — through both direct taxpayer liability and the downstream effect on electricity prices.
The Observation
There is a version of this story where Snowy 2.0 is just a very hard project that cost more than anyone expected, because big infrastructure projects often do. That version exists.
There is also the version where: - The government knew, monthly, how bad it was - Chose not to tell Parliament - Spent $600K suppressing the evidence - The minister's department head ended up on the board
Both versions can be true simultaneously.
The bill is $42 billion. It's public money. Anyway.
