There is a quiet revolution in this Budget in the form of a new fiscal strategy. For too long, there has been huge political pressure on an arbitrary debt-to-GDP ratio, but we carried the debt in other ways. We have a housing deficit, we have a transport deficit, we have a deficit of three waters infrastructure, we have an environmental deficit, and we have a social deficit. The new approach that's been announced by the Minister of Finance will now mean that arbitrary debt restrictions will not stop good fiscal infrastructure projects that stack up on all other metrics, such as cutting climate pollution.
