Senator McDONALD (Queensland) (15:01): My question— Honourable senators interjecting— The PRESIDENT: Senator McDonald, please resume your seat. I would expect Senator McDonald to be given the courtesy of all senators in this place and be allowed to ask her question in silence. Senator McDONALD: My question is to the Minister representing the Treasurer, Senator Gallagher. Today's national accounts have shown middle Australia is being crushed due to Labor's failure to manage the economy. Can you confirm today's national account showed that, over the past 18 months, mortgage interest payments have almost tripled, income taxes paid by household have risen by 27.3 per cent and, in the last year, real household disposable income has fallen by 6.6 per cent?
