Mr BOWEN (McMahon) (14:29): My question is to the Treasurer and refers to his previous answer. Why did the Treasurer fail to mention another Paul Keating quote from this morning: The GST is just a flat, bang you over the head, tax. It changes nothing; no behaviour, other than to put the tax weight onto the wrong people. The SPEAKER: The member for McMahon will not use props in questions. Mr Dutton interjecting— The SPEAKER: The minister for immigration will cease interjecting. The Treasurer has the call.
