Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (14:15): I thank Senator Duniam for his first supplementary question. The opposition have only got themselves to blame for the position that they now find themselves in. They purport to be a party of government. They went to the last election with a policy of net zero by 2050. We are progressing that because we also took that policy to the people. We're progressing that, and at every point in the process the opposition is opposed to trying to deal with this issue of decarbonising our economy. We haven't heard a single word from the opposition about how they intend to decarbonise the economy. (Time expired) The PRESIDENT: Senator Duniam, second supplementary?
