Mr TURNBULL (Wentworth—Prime Minister) (14:11): I thank the honourable member for his question. I can understand the anxiety that his constituents have when they consider the recklessness of the Labor Party in its proposals. There is no more important issue for the economic security of Australian families than the investment in their home. Ms Plibersek interjecting— The SPEAKER: The member for Sydney will cease interjecting Mr TURNBULL: Over 65 per cent of Australians' net worth is in residential real estate—and principally the family home. Ms Plibersek interjecting— The SPEAKER: The member for Sydney is warned. Mr TURNBULL: I will take that interjection. The member for Sydney is complaining that housing prices are too high and that people cannot afford to buy a house. What she wants to do is crash housing prices. She thinks that, by their measure, of a wrecking ball swung into an already vulnerable property market, they will knock down property prices and make it easier for people to buy homes. So the 70 per cent of Australians who own houses will see the value of their single most important asset smashed to fulfil an ideological crusade by the Labor Party designed, so she claims, to make it easier for people to buy a house. Ms Macklin interjecting— Mr Bowen interjecting— The SPEAKER: The member for Jagajaga and the member for McMahon will resume their seats. Mr TURNBULL: Let me tell you, even that leftist analysis of economics is wrong. If you get into a situation where property prices— Ms King interjecting— Ms Rowland interjecting— The SPEAKER: The member for Ballarat and the member for Greenway will cease interjecting. Mr TURNBULL: are declining, if you are in an environment—which the Labor Party will create—where property prices are on the slide, then people will not want to buy new houses. Homebuyers will hang off. When young couples buy a new house, do you think they buy it on the basis that it is going to go down? I do not think so. They buy it because they hope it will appreciate. Mr Dreyfus interjecting— The SPEAKER: The member for Isaacs will cease interjecting. Mr TURNBULL: They know that they have an alternative government across the table whose policy is not simply calculated to lower property prices and undermine the security of Australian families but, the Deputy Leader of the Labor Party is boasting across the chamber, that it is all designed to lower property prices. That is their goal. Mr Champion: What garbage! The SPEAKER: The member for Wakefield is warned. Mr TURNBULL: If they have their way, they will ask this parliament to legislate to smash property prices. Nothing could be more calculated to undermine the security of this country's economy. Every decision that individuals make is based on a perception of their own net asset position, and central to that is the value of their home. Ms Ryan interjecting— The SPEAKER: The member for Lalor will cease interjecting. Before I call the Leader of the Opposition, I remind the members for Moreton, Wakefield, Chifley and Sydney that they have been warned. The Leader of the Opposition has the call.
