Senator BIRMINGHAM (South Australia—Leader of the Opposition in the Senate) (14:56): My question is to the Leader of the Government in the Senate, Senator Wong. I refer to the proposed parliamentary sitting schedule for 2023 that has been widely distributed by the government and which shows that the government wants to scrap additional budget estimates for early next year, a departure from practice in place since the 1990s. Minister, when Labor was elected, the Prime Minister said: The Australian people deserve accountability and transparency … Why, then, is this government scrapping additional estimates and reducing Senate estimates scrutiny from the conventional four weeks in a normal year to just three weeks? Honourable senators interjecting— The PRESIDENT: We are fortunate that Senator Birmingham has a loud and clear voice, because it was very hard to hear the question from the interjections. Senator McKenzie interjecting— The PRESIDENT: Senator McKenzie, I've just brought the chamber to order.
