Senator WONG (South Australia—Minister for Finance and Deregulation) (14:05): As I have previously gone through on many occasions in this place, other countries are acting to mitigate climate change, other countries are acting to deal with the continued growth of emissions. There was a time when there were people on the other side, John Howard, Malcolm Turnbull— Honourable senators interjecting— The PRESIDENT: Senator Wong, resume your seat. If people are wishing to have a chat across the chamber, which is disorderly, I am entitled to hear the answer. Senator WONG: There was a time when there were sensible people on the other side of parliament—Malcolm Turnbull, and even former Prime Minister Howard—who understood the importance of a sensible approach to tackling climate change. There was a time when the senator who in high dudgeon is questioning me came into this chamber and argued to support the Carbon Pollution Reduction Scheme. So anybody listening would know that the reason those opposite are continuing on this campaign is that all they want to deal with when it comes to climate change is a fear campaign.
