Holden has confirmed October 20 as the end of production in Australia.
Workers at the Elizabeth plant were today told of the deadline to give them "certainty" going forward, more than three years after it first announced plans to end Australian production.
Holden Executive Director of Manufacturing, Richard Phillips said the end of manufacturing at the plant would "bring to a close more than 60 years" of history.
"We have tens of thousands of world-class cars to build in coming months and I know we all want to see Holden have great success in Australia for many years to come," he said.
The plant has been in use since 1963.
The company said more than 30,000 vehicles would be made before the cut-off date, and added of the nearly 700 people that were forced to leave the plant since 2015, 80 percent have "successfully transitioned" into new jobs or training.
Employees will have access to transition services and up to $3000 in approved training and $500 for financial advice.
More to come.
