Hon MICHAEL WOOD (Minister of Transport): Addressing the questions from Messrs Watts and Court, I believe, in respect of the question about how assessments might be carried out—for Mr Watts—I have addressed that now on several occasions to other members. In respect of the question about cost benefit, it doesn't necessarily fit into clause 4, nor do the questions about what forecast we might have about fuel prices going into the future. I think the best that I can say there is that the advice from officials is that there is still considerable uncertainty, given the international situation, as to how fuel prices will track, and so we believe, as a Government, it's best to be decisive and provide a good discount at this stage to assist people with those cost issues.
