The Whyalla steelworks in South Australia has begun cutting hundreds of jobs following its blast furnace did not restart.
Reports place the number of positions at risk at 500 or more, and some say over 600. The full scale of the cuts is not yet clear.
At least 146 workers are confirmed as losing their jobs permanently.
The furnace shutdown pushed the company into making the cuts. The steelworks has yet to make an official announcement about the job losses, but one was expected soon.
The job cuts come after the failed restart of the blast furnace on site.
