Senator BIRMINGHAM (South Australia—Minister for Education and Training and Manager of Government Business in the Senate) (14:45): I am delighted to say that we trust that the economic modelling that I know the South Australian Liberal Party have had done by Frontier Economics—an organisation that, indeed, the Labor Party have been happy to use themselves—is credible. I am sure their modelling is credible, demonstrating that households will save under their policy. I tell you what, households and businesses have been paying a lot more under Jay Weatherill's policy. I know that households and businesses will be happy to save every single dollar possible on their electricity bills. Senator Gallacher might wish to come in here— Senator Gallacher: Mr President, I rise on a point of order going to direct relevance. The question was whether we can expect $60 of meagre savings? The PRESIDENT: I'll call the minister; he's in order. Senator BIRMINGHAM: South Australians will be happy to save every single dollar possible—I am confident of that—and the modelling demonstrates it is $300. The PRESIDENT: Senator Gallacher, a final supplementary question.
