Senator BIRMINGHAM (South Australia—Minister for Finance, Leader of the Government in the Senate and Vice-President of the Executive Council) (15:30): I thank Senator Patrick for his question. The processes around finalising that answer have not been able to be finalised at this point in time. It has been a very busy period for all involved, as I've indicated to the Senate before. Through the life of this parliament, there have been record numbers of questions asked across questions on notice to the Senate chamber and across parliamentary estimates proceedings. Indeed, I think the questions total something close to that experienced in the previous two parliaments combined. The government has worked hard to provide answers and has delivered answers to record numbers of questions. I apologise to Senator Patrick in relation this one, but I don't have a further update for him.
