I'd like to ask a question in regards to category 2 light vehicle importers. And this is where vehicles are imported vehicle by vehicle and where charges are placed upon those vehicles dependent upon their carbon dioxide emissions. My understanding of this is, effectively, that each of those cars gets treated as an individual car rather than the type category A light vehicle importers, which, effectively, are looking more of a fleet level in terms of what are the charges and the overs and unders. And the question I've got in regards to the charges, it says in the new section 182(2), in clause 7, that "The charges are,—from 1 January 2023,—(i) $18.00 dollars per gram of carbon dioxide by which a used vehicle exceeds its target; and (ii) $36.00 per gram of carbon dioxide, by which a new imported vehicle exceeds its target;". My understanding of the difference there is that a used vehicle will come in later in its life, and therefore it has a shorter period of time. But the question I've got in relation to these charges—is there going to be a cap on the maximum amount that can be charged based upon these particular charges? And so if I was to import a used vehicle and it exceeded the target and I had to pay $18 per gram of carbon dioxide, what would be the maximum fee, if possible—is there a maximum fee? It doesn't seem to be that there is any sense of maximums set out in the primary legislation, so I assume that is something which may be considered as part of the regulations. If it is part of the regulations, is that something that the Minister has determined, that it will be a maximum fee? Will that maximum fee therefore also be different between the two different types of vehicles? So if I have imported a used vehicle I would assume, therefore, that the maximum fee for a used vehicle would be about half that of what the maximum fee of an imported vehicle would be.
