Today the federal treasurer, Scott Morrison, is expected to make an announcement about changes to how the GST take is divided between the states.
The changes are rolled out in stages, with the West Australian government to receive top-ups after the millennial mining boom has dried up, in the first stage of the plan.
The federal government will then commit hundreds of millions of dollars to the GST pool to ensure no state will receive less than seventy-five cents for each dollar they contribute.
Under the Productivity Commission's preferred plan that was originally sent to Morrison, only WA and NSW governments would have benefited from the changes to the formula.
