Mr TURNBULL (Wentworth—Prime Minister) (14:37): I thank the honourable member for his question. As I say, it does make me feel as though I have not been away; it is just the same questions they asked a week ago. It is good; it is very touching. Ms Macklin interjecting— The SPEAKER: The member for Jagajaga! Mr TURNBULL: The honourable member's rather feeble attempt to get a rise out of me will not be gratified, I am afraid. Let me simply say that the object of a full discussion on tax is not to salami slice the debate and rule out one thing after another. That is where the former, Labor, government got into trouble with the Henry tax review. That was a fundamental mistake. The honourable member knows that there should be a broad discussion. Ms Macklin interjecting— The SPEAKER: The member for Jagajaga is warned. Mr TURNBULL: Some of the proposals that they have put up are utterly fanciful. Nonetheless, we are not going to go down the road of ruling things in or out, because that defies the need for a full discussion. I will invite the shadow Treasurer's opposite number to add to this answer.
