The New South Wales and federal governments have agreed to spend $2.5 billion over 10 years to secure the future of Tomago Aluminium, Australia’s largest aluminium smelter. The bill gets split down the middle, with taxpayers in both jurisdictions carrying the weight while Rio Tinto keeps the plant running.
The prime minister and NSW premier are expected to visit the smelter in the NSW Hunter region on Thursday morning to sell the deal. That’s the choreography. The money comes first, the photo op follows.
Who Pays, Who Decides
Late last year, Rio Tinto warned the Tomago Aluminium plant could be forced to close when its energy supply contract ran out in 2028 because of the rising cost of renewable and coal-fired power. The company’s warning set the terms. Governments moved to meet them.
The smelter is currently Australia’s largest electricity user, consuming about 10 per cent of NSW’s total electricity supply annually. That scale matters because the public grid and public money are being bent around one industrial operation, with ordinary people left to absorb the costs and consequences of keeping it alive.
A joint statement from the NSW and federal governments said the funding package would "secure the future of aluminium smelting in the region". A spokesperson said the joint investment would deliver "a long-term renewable energy solution for the Tomago Aluminium smelter that supports commercially sustainable operations beyond 2028 and accelerates decarbonisation of more than 10 per cent of NSW's electricity grid".
That language does a lot of work. It dresses up a bailout as transition, and a subsidy as sustainability. The machinery of state and capital stays intact.
The spokesperson said the NSW government’s contribution is capped at $1.225 billion over 10 years from 2029. Rio Tinto will invest a minimum of $1.1 billion on top of the taxpayer funding to reduce its energy usage and gear the smelter toward renewables. That includes $100 million to drive further decarbonisation activities at the smelter and undertake an innovative demand-response program to support the NSW grid. The spokesperson said the demand-response program aims to position Tomago as the international leader in electricity demand response and flexibility services.
Workers Wait, Executives and Ministers Move
The smelter employs about 1,000 workers and has been operational 24 hours a day since 1983. Those workers spent months on edge, waiting for a decision made far above them. The Electrical Trades Union said workers had been on edge for months as they eagerly waited for an announcement about their future.
Union organiser Brad McDougall said a deal could not come fast enough. "It's been very difficult for all employees on the site," he said. "We get comments made like, 'I wake up every day not knowing if today is going to be the day', positive or negative ... so this news will be fantastic."
That’s the human cost buried inside the corporate rescue. People who keep the place running every day are left to live with uncertainty while governments and Rio Tinto haggle over the terms of survival.
Prime Minister Anthony Albanese and NSW Premier Chris Minns will visit the smelter on Thursday to tout the deal. During a previous visit to the Hunter site, the prime minister told Tomago workers he suspected a deal could be reached quickly. Plans later stalled when a clear-cut funding agreement could not be reached with NSW. It is understood the federal government wanted an even 50:50 funding split, similar to a deal inked with the Queensland government for the Boyne Aluminium Smelter near Gladstone. At the time, Mr Minns pushed back on the even-funding proposal, saying the deal was being led by the federal government and any contribution from the state must work in the interests of NSW taxpayers.
That argument over who pays doesn’t change who benefits. It only changes which branch of government gets to claim it protected the public purse while handing over billions to a giant industrial operator.
Bailouts as Routine
The rescue package follows a string of similar bailouts offered by the Albanese government to struggling heavy industries, including Glencore's Mount Isa Copper smelter and the struggling Nyrstar smelters in Tasmania and South Australia. One bailout becomes precedent for the next. The apparatus keeps finding public money for private industry.
Rio Tinto’s latest annual report showed it had recorded a $10 billion profit after tax across 2025, attributable to its owners. Its total aluminium and lithium projects were valued at $4.6 billion, up from $3.6 billion in 2024.
So while governments promise to "secure the future" of the smelter, the company behind it reports billions in profit and billions more in project value. The public pays to stabilize the operation. The owners keep the upside. That’s the arrangement, plain as day.
