PM announces $2.4bn for Whyalla steelworks
The prime minister told the workforce he knows “it’s been a difficult time for you.”
What we have done is to combine dollar for dollar on administration, to make sure that while the transition is going to make sure that the steelworks keep operating, you keep being paid, the people who are owed debts – some of those small businesses here in Whyalla – get paid.
In addition, the two governments would invest $2.4bn to “make sure that this transition occurs”, he said.
We regard that as an investment in our nation, we don’t regard it as a cost. Because when you invest in the nation, you get a return.
