Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (14:48): I thank Senator Bilyk for her first supplementary question, and to quote the Financial Review: Researchers cited by the Greens to push for a rent freeze concluded that cities that experimented with the controversial controls experienced no improvement in affordability— Opposition senators interjecting— Senator FARRELL: No! Listen to this: 'and ended up with poorer quality housing'. It's something the federal government cannot force upon the states, it's something many states have already ruled out and it's something the expert advice says won't work. The Greens need to decide which is more important—their campaigning or the people who need homes, because the way to help people in housing stress is to vote for the Housing Australia Future Fund and use social and affordable rentals. It would help. The delays have to stop. Australians in need can't afford it anymore. (Time expired) The PRESIDENT: Senator Bilyk, a second supplementary.
