We think that a modest co-payment— Mr Burke: Madam Speaker, I rise on a point of order. The question is not about the GP tax; it is about diagnostic imaging. The Prime Minister is not at all being directly relevant to diagnostic imaging. The SPEAKER: The question is about bulk-billing. The Prime Minister has the call. Mr ABBOTT: The only change the government is proposing is a $7 co-payment. How can it be unfair to have a $7 co-payment— Mr Champion interjecting— The SPEAKER: The member for Wakefield is warned! Mr ABBOTT: on GP visits when members opposite think that pensioners should face a $6 co-payment when they go to the pharmacist for their PBS drugs? What we are proposing is fair, it was reasonable. It was first introduced by Prime Minister Bob Hawke. Ms Claydon interjecting— The SPEAKER: The member for Newcastle is warned! Mr ABBOTT: As a result of policies, it was supported by the member for Jagajaga and, as we know, by the member for Fraser. It is good policy and it will help to keep our great Medicare system sustainable.
