Senator IAN MACDONALD (Queensland) (14:26): My question is also to Senator Sinodinos, the cabinet secretary, in his role representing the Minister for Trade and Investment, Mr Andrew Robb. It relates to the Northern Australia Investment Forum, which Mr Robb has been hosting along with, I might say, Senator Colbeck and the northern Australia minister— Opposition senators interjecting— The DEPUTY PRESIDENT: Just a moment, Senator Macdonald. Order! Senator Cameron: You like to dish it out but you can't take it! The PRESIDENT: Order, Senator Cameron! Senator Macdonald, apart from who the question is addressed to, could you commence your question again. Senator IAN MACDONALD: In case people did not hear it, I am saying the question relates to the Northern Australia Investment Forum, which Mr Robb and, indeed, Senator Colbeck— Opposition senators interjecting— The PRESIDENT: Order, on my left! Senator Brandis: Mr President, on a point of order: as you have often observed and ruled, interjection is disorderly but this is more than interjection. This is like a football crowd! This question is inaudible to me, sitting as close as I am to Senator Macdonald, because of the football-crowd barracking coming from the other side. The PRESIDENT: Thank you, Senator Brandis. Senator Wong, on the point of order. Senator Wong: Mr President, I have another point of order. First, obviously, perhaps the attorney should stop defaming footy supporters. But, more importantly— The PRESIDENT: That is not a point of order. Senator Wong: Sorry, Mr President. The clock was reset. Was that at your direction? The PRESIDENT: I asked the senator to start the question again. Not only could Senator Brandis not hear Senator Macdonald but also I could not hear Senator Macdonald. I remind all senators—on both sides—that interjections are disorderly and just remind you that you are televised and the people of Australia listen to us through radio. Senator Macdonald, could you start the question again. Senator IAN MACDONALD: I indicate the question relates to the Northern Australia Investment Forum, which Mr Robb along with Senator Colbeck and the northern Australia minister, recently, hosted in Darwin. I asked the minister if he could explain to senators—particularly those on the other side who, clearly, have no idea and no interest in northern Australia—what the Northern Australia Investment Forum was all about. In doing so, he will be able to assist the members of the Australian public in understanding what an important event the Northern Australia Investment Forum was. Senator Cameron: You like to dish it out, but you can't take it! The PRESIDENT: Senator Cameron! Senator Jacinta Collins: Was it a good event, after all that? Senator Cameron: You've got a big glass jaw! The PRESIDENT: On my left!
