The scale of this ETS revenue that we're talking about is in the hundreds of millions of dollars. It's not chunk change; this is a lot of money that we're talking about. If you change the ETS to make it look more like a tax that is involving such a massive amount of revenue, then it is our view that there must be more checks and balances on those pricing tools—in this case, the formula that the Minister uses to, effectively, set the price at auction. So we'll introduce a tabled amendment to flesh this out and to have a look at this, and we will debate it later on.
