Former Liberal treasurer Peter Costello has launched a broadside against both the Labor Party and the Coalition, accusing each of bad economic decisions in recent years.
Costello, the country's longest-serving federal treasurer, slammed Australia's current level of debt and questioned why governments had not done more to "rein in spending" and balance the budget.
"The fastest growing area of government expenditure now is interest on debt. If you can believe it, the interest payments that we have to make on our debt are growing faster than the NDIS," he told ABC RN's Between the Lines.
