Senator BIRMINGHAM (South Australia—Leader of the Opposition in the Senate) (14:17): As members and senators leave this place today, a household with an average mortgage of $750,000 is paying $24,000 a year more in interest than they were when Labor was elected, with no sign of relief on the horizon. An opposition senator interjecting— Senator BIRMINGHAM: Mr Albanese has broken promise after promise, including his promise to cut electricity prices by $275 and his insistence that he wouldn't touch stage 3 tax cuts. Has the prime minister forgotten his promise of cheaper mortgages and cheaper electricity? Has he? Honourable senators interjecting— The PRESIDENT: Order! Senator Birmingham has the right to ask his question in silence. An honourable senator interjecting— The PRESIDENT: I beg your pardon. They needed to be quietened down anyway! And, Senator O'Sullivan, I think that was you who whistled before. If it wasn't, I apologise, but whistling in the Senate is absolutely inappropriate. Senator O'Sullivan: I can't whistle! The PRESIDENT: If it wasn't you, Senator O'Sullivan, I apologise. Honourable senators interjecting— The PRESIDENT: Order! Someone on my left whistled; It is absolutely inappropriate. I'm not going to stop and call the chamber to order every few minutes. A government senator interjecting— The PRESIDENT: Order on my right as well! I'm waiting to call Senator Wong. Minister Wong.
