Mr BOWEN (McMahon) (14:38): My question is to the Treasurer. This morning the Treasurer introduced legislation to implement the government's entire seven-year personal income tax scheme. Already today, at the National Press Club, the Treasurer refused to say what the year-by-year cost of the scheme would be. Treasurer, will you tell the parliament the year-by-year cost of the government's personal income tax scheme over those seven years?
