Senator BRANDIS (Queensland—Deputy Leader of the Opposition in the Senate) (14:19): Mr President, I ask a further supplementary question. Minister, I refer you to your statement on 29 June that: … there’s really only one set of numbers I’m worried about. That’s making sure we get back into surplus by 2012-13 … Minister, do you regard that as a promise? Should the Australian people have as much faith in this promise to return the budget to surplus by 2012-13 as in the Prime Minister's promise that there will be no carbon tax under the government she leads?
