Senator NASH (New South Wales—Deputy Leader of The Nationals in the Senate) (14:39): My question is to the Minister representing the Minister for School Education, Early Childhood and Youth, Senator Kim Carr. Is the minister aware of New South Wales Treasury modelling, based on the federal government's own carbon modelling, which shows that the Labor-Greens carbon tax will cost New South Wales public schools $77 million over the next four years, or $9,000 per school per year? Honourable senators interjecting— The PRESIDENT: Order! On both sides. Senator Nash is entitled to be heard in silence. Senator NASH: What compensation does the government intend to provide for this heavy burden on New South Wales schools, particularly those in regional areas? How is this consistent with Labor's so-called education revolution?
