Senator FIFIELD (Victoria—Manager of Government Business in the Senate, Minister for Communications and Minister for the Arts) (14:11): As I have said— Senator Cameron: Point of order. Senator FIFIELD: I haven't said a word! The PRESIDENT: A point of order, Senator Cameron? Senator Cameron: Senator Macdonald continually interjects and is continually calling Senator Wong 'Penny'. You must have heard it. He must stop that. Honourable senators interjecting— The PRESIDENT: Order! On the point of order, Senator Macdonald? Senator Ian Macdonald: Senator Wong has been so good in the last few weeks, but she is breaking out as it gets close to Christmas! The PRESIDENT: There is no point of order. Senator Ian Macdonald: I was just trying to help you keep her quiet, not shouting through all of question time. The PRESIDENT: Thank you, Senator Macdonald! Thank you, Senator Cameron; that is a timely reminder for all senators not to interject during question time. One can only hope that you will not. Minister, you have the call. Senator FIFIELD: NBN's business case is strong. NBN received strong indicative credit ratings. The government has taken an entirely prudent and appropriate approach. Can I remind colleagues, again, where the NBN is today compared to where the NBN was in 2013. Opposition senators interjecting— The PRESIDENT: Order, on my left! Senator FIFIELD: The NBN, under those opposite, was a failed project—$6½ billion spent by those opposite and only 51,000 paying customers. Today, the NBN is available to in excess of three million Australians. We will complete this six to eight years ahead of you.
