Mr President, I ask a further supplementary question. Given the minister's failure to give straight answers to very straight questions, why should Australians believe this government over independent modelling that indicates Labor's imposition of the world's highest carbon tax would lead to a multibillion-dollar budget blow-out? Why is the government afraid of updating the Treasury modelling to reflect the real-world scenario where world carbon prices are around one-third of those assumed in the modelling on which the government so greatly depends and relies?
