The Greens will not rubber stamp any proposals from the government's landmark jobs and skills summit, leader Adam Bandt warns.
The minor party, which holds the balance of power in the Senate along with the cross bench, will not pass any legislation that doesn't lift wages.
"The government must lift wages now. Not in three years, not when there have been skills reforms, but now," Mr Bandt said.
"The Greens won't be a rubber stamp for government side-deals with big corporations."
Backing the push by the Australian Council of Trade Unions for industry-wide bargaining, Mr Bandt says the Greens will go even further to amend any legislation in the Senate to include a greater role for government in setting wages across the board.
"If and when any proposals from the jobs summit hit the Senate, the Greens will push to change the law to guarantee wage rises," Mr Bandt said.
"The government should treat low wages, especially in the care economy, as urgently as they're treating skills shortages.
"We need to lift low wages from the bottom up, not just wait for any future skills reform to trickle down."
Mr Bandt will attend the summit with Senator Barbara Pocock and will outline his party's proposal to reform the Fair Work Act.
The Greens have raised concerns any changes would not affect workers covered by enterprise agreements still in force for up to three years.
The party will push to set the minimum wage at 60 per cent of the full time median wage, which would increase the new minimum wage to $23.76 an hour.
It will also push to increase the minimum wage in industries dominated by women faster with an award rate guarantee of at least 0.5 per cent above inflation in these sectors.
