Mr TURNBULL (Wentworth—Prime Minister) (14:24): I thank the honourable member for his question. The honourable member doesn't want any Australian to have their say unless they're a member of the federal parliament. He doesn't want Australians to be consulted. He said 20 per cent of his constituents are not on the electoral roll. Then they wouldn't have got a say in a compulsory plebiscite either, and they don't get a say in an election. Mr Snowdon interjecting— The SPEAKER: The member for Lingiari is warned. Mr TURNBULL: So it's far from a tribute to the energies of the honourable member that he hasn't got all those constituents onto the electoral roll. So I would encourage him, as an enthusiast for democracy, to get those constituents onto the electoral roll so that they will be able to participate in this plebiscite, which will ensure that every Australian has their say on this issue. The only reason it isn't a compulsory attendance ballot is the Labor Party's opposition. If I may add to an earlier answer, Mr Speaker: when the Leader of the Opposition opened up by mingling same-sex marriage and energy, I responded by saying the two issues did not have anything in common. Ms Husar interjecting— The SPEAKER: The member for Lindsay is warned. Mr TURNBULL: They do have one thing in common: over six years of Labor government, the Labor Party did nothing about either.
