The manufacturing union wants the Abbott government to abandon its inquiry into the country's car manufacturing sector and provide an immediate injection of funds.
Australian Manufacturing Workers Union vehicle division secretary Dave Smith says the automotive industry is in crisis and urgent action is needed.
"I'd be calling on the government today to forget about a Productivity Commission (inquiry), think about jobs, think about Australian workers and just get in there and support the industry at a time when it most needs it," he told reporters in Melbourne on Friday.
The government has asked the commission to inquire into the sector with a report due by the end of March 2014.
Mr Smith urged the government to match the previous Labor government's package that gave assistance until 2022.
He says the industry won't survive without co-investment.
"Every car on Australian roads - imported vehicles, locally made vehicles - are subsidised in one form or another," he said.
"If the government can't get its head around that, the industry will just simply go to a country that will support it.
"You can't just look at it as money, it's an investment in Australia's future."
Toyota Australia has told union officials it wants to vary the terms and conditions of its workplace agreement with staff to improve productivity and competitiveness.
Mr Smith said the company would provide a list of issues it wanted to discuss with the union on Friday afternoon.
He said Toyota was being squeezed by the high Australian dollar, but it was important to ride out the situation so the industry could capitalise when the dollar eventually fell.
