Senator PAYNE (New South Wales—Minister for Human Services) (14:22): I thank Senator Whish-Wilson very much for his question. As to the circumstances in the United States, the Minister for Trade and Investment, Minister Robb, has spoken at some length about this and indicated that it is a circumstance of— Honourable senators interjecting— Senator Brandis: Mr President, on a point of order: I understand that this is a robust chamber, and interjections, although disorderly, are not unknown. But there is a difference between interjections and Labor frontbenchers, including the leader, yelling at members of the government while they are trying to answer questions, and I would ask you to enforce the standing orders. Honourable senators interjecting— The PRESIDENT: I ask all senators to come to order. Senator PAYNE: I do thank Senator Brandis for that intervention. But the day I need protection from Senator Carr will be the day I am scared by a limp lettuce leaf! As I was saying in relation to the developments in the United States, which Senator Whish-Wilson referred to in his question, these are always a matter of great cut and thrust in both domestic and international politics. The circumstances in the United States are no exception from that exercise, the highly political exercise, of cut and thrust that is associated with these matters. The trade and investment minister here in Australia, Mr Robb, has gone to great lengths to engage with members of the parliament, including extending an offer to Senator Whish-Wilson—an offer which was taken up by other senators and other members of the parliament in this chamber—to view the material that is available in relation to the Trans-Pacific Partnership. Others in the parliament have taken that up. I understand Senator Whish-Wilson chose not to. That is, of course, his choice and a matter for him and a matter for the Greens. It is not a matter for the government. The government made the offer. It was not taken up by Senator Whish-Wilson. There are other members who did avail themselves of the opportunity. We of course remain hopeful that the relevant legislation will ultimately pass, which will provide the momentum we need to conclude the negotiations. The trade minister has made that quite clear—and I reiterate his remarks.
