Senator RUSTON (South Australia—Assistant Minister for Agriculture and Water Resources) (15:02): I seek leave to make a short statement to add some information on a question asked of Senator Birmingham by Senator Hanson in question time yesterday. Senator Wong: The opposition will do the courtesy of granting leave, but it is customary for the minister who was asked the question to answer the question, not to palm it off to someone else. Senator Birmingham: I seek indulgence on the point that Senator Wong has made. I think if Senator Wong reflects on the question she will find that much of the question related to the agriculture portfolio, which I do not handle in the chamber. Indeed, if Senator Wong would prefer, we can wait and I'll come back at another time and provide the information that Senator Ruston is offering to provide to the chamber at this point in time. If Senator Wong wants to be hung up on that process, that is fine. Senator Ruston, who directly handles these matters in a ministerial sense in a number of ways, has brought information as additional information to the chamber. Senator Wong: On the point of order, I'm not being hung up; it's about ministerial accountability. She is not the minister who represents the member of the executive who was asked the question in this chamber. On this occasion, we will grant leave, but I would make it clear that it is the opposition's view that the government decides who represents whom. We will ask the ministers representing the relevant portfolio and we would expect any additions to answers to be given by that minister. The DEPUTY PRESIDENT: Thank you, Senator Wong. There is a question before the Senate. Senator Ruston asked if leave is granted. Is leave granted? There being no objection, leave is granted.
