Mr President, I ask a supplementary question. Given the government's failure to undertake the Treasury modelling of its carbon price at the price of $23 per tonne it is actually proposing, can the minister advise whether the Treasury modelling is based on a 50 per cent cap on the purchase of permits from overseas or does it still assume the unlimited purchase of permits?
