Mr TED O'BRIEN (Fairfax—Deputy Leader of the Opposition) (14:08): My question goes to the Prime Minister. Given the RBA's decision to keep interest rates on hold, millions of Australian mortgage holders will start wondering whether interest rates are as low as they'll ever go under this government. The Treasurer's spending spree is at the heart of the problem. Government spending is running four times faster than the economy. Given that the Treasurer repeatedly refuses to take responsibility for this, Prime Minister, will you take responsibility? Honourable members interjecting— Mr Ted O'Brien interjecting— The SPEAKER: Order! No, we're not having this. The Leader of the House? Mr Burke: Mr Speaker, there are lots of things in the standing orders that are described as disorderly. Continuing to interject when you're out of your seat, as the member was, is described as highly disorderly, and I just draw your attention to behaviour that he was warned about yesterday. The SPEAKER: I'm not particularly enamoured with people asking a question—and you know the primacy of the question that I believe it's important for every member to be heard in silence—and then having another go when they're sitting down. I don't think that's fair, and if we go down that path all the time it's going to lead to a pretty bad question time. That means the member for Fairfax is now on a warning, because of that behaviour. Everyone, we want to do things respectfully, follow the rules and follow the proper processes for everyone, so there will be no more of that behaviour. I thank the Leader of the House for raising it, but I'm not particularly enamoured when people don't follow the rules.
