Senator PARER (Minister for Resources and Energy)(11.44 a.m.) —I am happy to hear Senator Brown's response but before doing so I would just like to make the comment that we have before us a bill that is to do with the tightening of the eligibility for the diesel fuel rebate. Senator Cook mentioned—and I agree with him—that this is probably not the appropriate place to consider this sort of amendment. If there is to be further work done on it, it should be done outside this bill. I think one of the recommendations of Senator Cook was for Senator Brown to pursue it and, if necessary, bring in a private member's bill so it can be studied by everyone. What I would not like to see, in view of the delays we have had so far, is this bill which tightens the eligibility for the diesel fuel rebate being held up for another period of time.
