The federal government repeated its 2025 call for a pay bump above the inflation rate in its submission to the Fair Work Commission's annual wage review.
Such an increase should be "consistent with underlying inflation returning to the Reserve Bank of Australia's (two to three per cent) target band in 2026/27", Treasurer Jim Chalmers and Employment Minister Amanda Rishworth said on Thursday.
Each year, the industrial umpire determines how much extra the more than 2.6 million Australians on minimum and award wages will get paid.
The commission decided in 2025, as inflation was on the way down, that workers deserved an above-inflation 3.5 per cent pay bump to help "catch up" with the fall in real incomes during the post-COVID-19 pandemic price spike.
But the return of inflationary pressures and war in the Middle East has complicated the commission's decision for 2026.
Unions argue low-paid workers are still behind from the previous inflation spike and will fall even further behind as fuel costs surge and flow through to prices across the economy.
The Australian Council of Trade Unions has called for a five per cent increase, which would raise the hourly minimum wage to $26.19.
Business groups warn a pay rise above inflation, which came in at 3.7 per cent in the 12 months to February, would exacerbate price increases fuelled by soaring oil costs.
That, in turn, could force the Reserve Bank to raise interest rates further.
Australian Chamber of Commerce and Industry chief executive Andrew McKellar called for a 3.5 per cent increase, arguing low productivity growth had reduced the rate at which wages could grow without lifting consumer prices.
"Any cost increase pushing above existing inflation at the moment, if it's not fully offset by productivity gains, is going to be unhelpful," he told AAP.
"If we continue to chase our tail with ever-higher wage claims, ever-higher cost pressures, it's only going to add fuel to the inflation fire."
The government does not nominate a specific wage increase figure, but its recommendation for a real wage rise points to a lift above inflation, which is tipped to climb as high as five per cent in the second quarter.
"Workers are doing it tough right now and that's why we think they should get a sustainable real wage increase," Dr Chalmers said.
Ms Rishworth pushed back at the suggestion a real wage rise would add to inflation, claiming wages were not a key driver of recent inflation pressures.
Lower-paid workers were more exposed to unexpected financial shocks and experienced greater financial hardship, she said.
Treasury has modelled two scenarios for the impact of the Middle East war on Australia's economy, including a pessimistic scenario that forecasts inflation to peak at five per cent in 2026.
Ms Rishworth would not say whether the government would support a wage increase above that figure if Treasury's modelling came to pass.
The Fair Work Commission will conduct hearings in May before handing down its annual wage review decision in June.
The pay rise will kick in from July 1.
