Senator WONG: I'll take the interjection from the Acting Leader of the Opposition in the Senate. 'We didn't make the promise,' that's true. You never made that promise because you never saw housing as a priority, so you didn't even bother making a promise or setting an ambitious target. You did not regard housing as a priority. Well, we do, and we are up for the challenge of investing money, investing funds, investing resources and working with the states and territories to deliver more houses for more Australians. The PRESIDENT: Senator Smith, second supplementary?
