Mathias Cormann (WA, Liberal Party, Shadow Assistant Treasurer) Share this | Hansard source

My question is to the Minister representing the Minister for Climate Change and Energy Efficiency, Senator Wong. I refer Senator Wong to answers she gave to questions about the carbon tax on Tuesday and Wednesday this week, where she referred to Treasury modelling to support her various assertions. Will the minister confirm that the models used by Treasury for its carbon tax modelling—ABARES' model, the GTEM; and Monash University's model, the MMRF model—and all other relevant parameters, frameworks and assumptions used by Treasury have not been made public to the extent necessary to enable third parties to independently scrutinise that Treasury modelling?

Is the minister aware that, in contrast, when the former coalition government asked the Productivity Commission to assess the National Reform Agenda it ensured that the MMRF model used by the commission was made fully available so that others could independently scrutinise all the modelling scenarios? Why is this government not doing the same?
