Senator HILL (Minister for the Environment and Heritage) (11:53 AM) —I rise briefly to say that we oppose the motion. We are a government that is strongly committed to reducing air pollution. It is interesting that surveys indicate that to Australians air quality in the major cities is still the number one environment issue. I will not take the time of the Senate today to remind honourable senators of the whole range of initiatives we have taken to improve air quality in this country, but those initiatives exist and they are being implemented. One of them concerned the importation of second-hand engines. We have, nevertheless, listened to representations of the industry in terms of where they have made a case that the engines being imported can in fact contribute to a better environmental outcome by replacing current engines that are more polluting. We have listened to those representations constructively and are looking for a resolution that can be of benefit to their industryin other words, a win in terms of economic outcomes but in particular a win in terms of environmental outcomes. Because we are close to achieving that objective, we really do not see that a further Senate inquiry is going to help us in that task. For that reason, we oppose the reference.
