Minister, one of the things we heard during the Senate committee from a number of people, including the Australian Workers Union national secretary, Daniel Walton, who we've heard a lot about during the Committee of the Whole so far, was that there was a need for a carbon border adjustment mechanism. My understanding is that the government has committed to consultation on a CBAM. I'm interested to know what is a realistic time line for the implementation of a CBAM, should the consultation show that this is something that has widespread support.
