Senator BILYK (Tasmania—Deputy Opposition Whip in the Senate) (14:18): My question is to the Minister for Communications, Senator Fifield. On 12 December 2013 Mr Turnbull said that his strategic review of the NBN was a 'thorough and objective analysis'. I refer to leaked nbn documents— Senator Ian Macdonald interjecting— Senator BILYK: which show that the cost of fixing up the old copper network that Mr Turnbull bought back from Telstra has blown out by up to 900 per cent. Did this government direct nbn to roll out a second-rate network on the basis of advice that was hopelessly wrong? Senator Wong: Mr President, on a point of order: Senator Macdonald interjects on every opposition question every single time. I am asking you, as President, to get him to desist. Government senators interjecting— A government senator: Are you serious? Senator Wong: Yes, I am serious. He does it every single time on every single opposition question. Frankly, I know that you hear it, and, with respect, Mr President, something ought to be done about it. Senator Cormann: Mr President, on the point of order: Senator Wong may well be right that, on occasion, Senator Macdonald interjects on opposition questions. But the Leader of the Opposition in the Senate interjects on every government answer. On the point of order: there should be one rule for all. If there is a rule that the Leader of the Opposition in the Senate wants to impose on this side of the chamber, she should comply with it herself. The PRESIDENT: On the points of order: both points of order are absolutely correct, and I remind all senators, as I have done on numerous occasions this week, that interjections are disorderly during a question or an answer, or at any other time. If I had to pull up every senator for every interjection, we would not get to question 1, possibly. Every senator has a responsibility not to interject. Senator Sterle: Good one, Macca. Now we are all in trouble! The PRESIDENT: Yes, Senator Sterle; you all are in trouble.
