Senator NASH (New South Wales—Deputy Leader of The Nationals in the Senate and Assistant Minister for Health) (14:16): I can advise the chamber that at the time of Senator Wong's question yesterday I did not have every detail of information at hand. Opposition senators interjecting— The PRESIDENT: Order! The minister is entitled to be heard in silence. Senator NASH: Thank you. In relation to the timing question that the senator asked me, having made further checks after question time yesterday, I advise the Senate at the first opportunity that my chief of staff was a shareholder of the company APA. Opposition senators interjecting— The PRESIDENT: Order! Order, senators on my left. When there is silence on my left I will ask the minister to continue. Senator NASH: I advised the Senate at the first opportunity that my chief of staff is a shareholder of the company APA. As the Leader of the Opposition would know, I also did the opposition the courtesy of advising them of the matter that I was going to raise during the adjournment period. I can also indicate to the Senate that my chief of staff receives no income from that shareholding.
