Senator WATT (Queensland—Minister for Agriculture, Fisheries and Forestry and Minister for Emergency Management) (14:36): Thank you, Senator Chandler. The minister has repeatedly made clear throughout this entire debate that her actions were only ever based on one factor, and that was the national interest of Australia. Throughout this debate, the opposition has repeatedly asserted that Mr Alan Joyce—as opposed to Mr Barnaby Joyce; another Joyce with an interest in aviation—has exerted some sort of influence over this decision. But I also note that the opposition has never been able to provide one skerrick of evidence to back up that assertion. I saw through the referendum campaign that, at one point, Mr Dutton was claiming that Mr Joyce had influenced the Prime Minister's decision about the Voice—again, no evidence; just going around making assertions. I would invite the opposition to provide just one skerrick of evidence to back up the assertions that it has been making now for weeks. I think it is quite telling that in a debate that has been going on for probably the best part of three months, the opposition has not been able to provide any evidence to back up that assertion. The PRESIDENT: Minister Watt, please resume your seat. Senator Birmingham? Senator Birmingham: To respond to the minister's invitation, did Minister King speak with Mr Joyce— The PRESIDENT: Senator Birmingham, that is not a point of order. Minister Watt, please continue. Senator WATT: It's nice to hear from the Leader of the Opposition in the Senate for a change. We don't really hear a lot from him these days. As I say, the opposition has never been able to provide a skerrick of evidence to back up the assertion that it makes. It has been engaged in a campaign of smear against Minister King for the best part of three months without any evidence to back up its claims. I stand behind what Minister King has said, which is that the government's actions were at all times based on our decision as to the national interest, just as previous decisions made by former coalition transport ministers, such as Michael McCormack, to stop Qatar from having extra flights. I don't remember the opposition having any concerns about that; it is only when it's a Labor decision. The PRESIDENT: Senator Chandler, a first supplementary?
