Holden will talk with state and federal governments before revealing how much it will kick in to an assistance package despite calls from South Australia for it to do more than the suggested $20 million.
The federal government has announced a $100 million package to help boost jobs in Victoria and SA.
The Commonwealth will contribute $60 million and wants Holden to contribute about $20 million, with the rest to come from the two state governments.
Details of how the funding will be distributed are yet to be revealed.
Holden spokesman George Svigos said the company welcomed Wednesday's announcement which followed the company's decision to stop local car production by the end of 2017.

"We look forward to working with all levels of government to support our employees through transition," he said.
"We will be in discussions with all governments in coming months over our involvement in this package and our contribution to it."
South Australian Premier Jay Weatherill said Holden should make a substantial contribution.
"Holden need to be accountable," he said.
"I want Holden to be part of this agreement and we'll be advancing propositions to Holden that go well beyond the contribution of $20 million."
