Senator CORMANN (Western Australia) (15:25): Pursuant to standing order 74(5) I ask Senator Arbib, the Assistant Treasurer, for an explanation as to why 293 questions that were taken on notice by Treasury and its associated agencies more than three months ago during the last Senate estimates remain unanswered 78 days after the answers were due. Given that we are now less than a week away from the next estimates, I am really interested to know what the government's explanation is for that.
