The Australian Workers' Union is pushing NSW and federal Labor to finalise Tomago smelter funding before the party's state conference, as the governments argue over cost, timing and energy terms beyond 2028.

The Australian Workers' Union is stepping up pressure on the Albanese and Minns governments to lock in a funding deal for Tomago before the NSW Labor conference on July 4-5, arguing the smelter's future should not be left waiting behind other budget priorities.

The dispute has become a test of Labor's handling of a major industrial rescue, with union leaders, NSW ministers and federal officials all signalling different views on who should pay, how much should be committed and what sort of power arrangement Tomago needs after 2028.

The Tomago aluminium smelter is one of the Hunter region's biggest industrial employers and a major power user. Its long-term viability is tied to access to affordable electricity, and the current bargaining is centred on whether governments can put a commercial energy pathway in place for the next decade.

Union pressure before conference

The AWU is backing a motion to the NSW Labor conference that says further delay to a joint funding deal is not acceptable. The union is arguing that the governments should move on Tomago before spending on other politically sensitive items.

Tony Callinan, the AWU's NSW secretary, has indicated the union is prepared to use its political leverage if the talks drag on. The union's message is that the plant's future should come ahead of commitments such as a gun buyback and shark mitigation spending.

The push is aimed squarely at Labor figures who will gather at the conference in early July, where the issue is expected to carry weight because of its implications for jobs in the Hunter and for the party's industrial credentials.

How the funding fight got here

In December 2025, the Commonwealth and NSW announced a plan to keep Tomago open beyond 2028 with subsidised clean power, but key details were left to later negotiations. Since then, the question of who carries the larger share of the rescue has remained unresolved.

In April, federal Industry Minister Tim Ayres pushed NSW to share the cost, saying the plant was strategically important and needed a durable plan. That set up a familiar split: NSW has suggested Canberra bears primary responsibility because of its earlier commitment, while the Commonwealth has continued to press for shared funding.

The issue returned to prominence again after NSW's budget on June 23, which included a $1.1 billion contingency fund that could be used for Tomago and other commitments. Treasurer Daniel Mookhey has said the fund is not reserved for Tomago alone.

The budget squeeze

That contingency pool has sharpened the politics around the deal. The union wants Tomago prioritised, but NSW has placed the possible funding inside a broader bucket that also covers other government priorities.

The size of any Tomago support package has not been publicly settled, and neither has the final ratio between state and federal contributions. Those unresolved questions are at the centre of the current standoff.

Federal officials are also pressing for a longer-term energy arrangement. Ayres' office says Tomago needs a power deal running from 2029 to 2039 if it is to remain viable beyond its current planning horizon.

What happens next

The next clear checkpoint is the NSW Labor conference, where the AWU motion could be adopted or amended. That would not by itself settle the funding dispute, but it would increase pressure on the governments to close the gap.

Watchpoints now include whether NSW and the Commonwealth announce a joint funding package, whether the $1.1 billion contingency fund is partly committed to Tomago, and whether Tomago, Rio Tinto or government ministers provide clearer guidance on the subsidy size and timing.

For workers in the Hunter, the stakes are immediate: the smelter supports thousands of jobs directly and indirectly, and its future affects the wider regional economy. For Labor, the issue is also political, landing just as the party tries to manage competing claims about jobs, industry support and budget discipline before the March 2027 state election.
