Ms BUTLER (Griffith) (15:01): My question is to the Treasurer. This morning, Liberal Senator Amanda Stoker said about Labor's request for more information on the cost of the government's income tax scheme: If it means they need more information to do that, I believe that's being organised. Can the Treasurer tell us when the government is going to release the year-by-year cost of each stage of his seven-year personal income tax scheme?
