Senator WATT (Queensland—Minister for the Environment and Water) (14:42): As I said last week, Senator Hanson-Young, I have one very easy suggestion for any member of the Greens party who doesn't want to see us pass these laws with the support of the coalition. That's that the Green party could actually back Labor to achieve environmental reform not continue the blocking that we saw from you in the last term where you blocked housing, where you blocked environmental reform and where you teamed up with the coalition to do it. How about you stand up for the environment and back environmental reform in the way that we're putting forward? The PRESIDENT: Senator Hanson-Young, first supplementary?
