Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (14:21): I thank Senator Waters for her first supplementary question. I support the truth in advertising legislation. I saw it at work in the Black by-election in South Australia. Unfortunately, I know the Greens vote collapsed— Honourable senators interjecting— Senator FARRELL: Yes, it's very sad. I know the Greens vote collapsed in that by-election, and you're obviously very worried about it. I won't get onto what happened to the Liberals— The PRESIDENT: Minister Farrell, please resume your seat. I've got Senator Waters on her feet. Senator Waters: On a point of order—this is why we need truth in political advertising; our vote went up—my question went to why you are delaying those reforms. The PRESIDENT: Senator Waters, if you are on your feet, you need to indicate that you're calling a point of order. You didn't do that. Honourable senators interjecting— The PRESIDENT: I'm going to remind those at the back of the chamber that, when Senator Waters asked her question, she was heard in silence. I'm asking you to stop the interjections so the minister can continue with his answer. Senator FARRELL: You're right, Senator Waters. The real collapse on Saturday was on that side of the chamber. There was a 20 per cent swing to the Labor Party. The truth in advertising provisions were used in that election because these people were making false claims about the Labor Party. I see the benefit, but, as I've said to you on— (Time expired) The PRESIDENT: Senator Waters, second supplementary?
