Senator FIFIELD (Victoria—Minister for Communications, Minister for the Arts and Deputy Leader of the Government in the Senate) (14:32): As colleagues would be well aware, the NBN has a mandate from the government to conduct the rollout of the NBN, according to what's referred to as a multi-technology mix. That means that NBN can choose the technology that makes sense in a given area to see the NBN rolled out fastest and at lowest cost. That is the reason why the NBN will be completed by 2020—a good six to eight years sooner than would have been the case under those opposite. The PRESIDENT: Senator O'Neill, on a point of order. Senator O'Neill: Thank you, Mr President. The minister was asked if he could provide an update on what it would cost to replace the unreliable and corroding NBN with 5G. Could I ask you to draw his attention to the detail of the question? The PRESIDENT: I can't instruct a minister how to answer the question. You have kindly reminded him. Senator Fifield. Senator FIFIELD: As I was saying, the multi-technology mix approach is the reason why the NBN will be finished six to eight years sooner than would have been the case under those opposite, and at about $30 billion less cost. Opposition senators interjecting— The PRESIDENT: Order on my left! Senator FIFIELD: I was able to update colleagues yesterday with the half-yearly results of the NBN. I am pleased to report that revenue is up, that we have more than half of the nation available to access the NBN. As a part of announcing the half-yearly results yesterday, Mr Morrow did undertake a number of interviews and in those— The PRESIDENT: Order! Senator Fifield. Senator O'Neill, on a point of order. Senator O'Neill: I just draw your attention, Mr President, to the fact that 5G wireless has not been mentioned at all, at any point, of his answer. There are 41 seconds remaining. The minister needs to address that vital piece of information. The PRESIDENT: I take the opportunity to remind the minister of the question asked. I call the minister. Senator FIFIELD: As I was saying, Mr President, yesterday, as part of the half-yearly results, Mr Morrow did undertake a number of interviews and in those interviews he did canvas a number of issues, one of which was the issue of 5G and the issue of mobile substitutability for some of the services that the National Broadband Network provides. You would expect that those are the sorts of issues that the NBN CEO would canvass. The PRESIDENT: Senator O'Neill, a supplementary question.
