Senator IAN MACDONALD (Queensland) (14:45): Mr President, I ask a further supplementary question. Opposition senators interjecting— The PRESIDENT: Just wait a minute, Senator Macdonald. You are being interjected on by your own side. Senator IAN MACDONALD: That is fine; they are very good interjections, I might say, Mr President. The PRESIDENT: You are entitled to be heard in silence, Senator Macdonald, regardless of what side. Senator IAN MACDONALD: I ask the minister: will the government do anything to support the local manufacturing industry in view of the stated concerns by both Ford and Holden as they 'reassess their commitment' to manufacturing in Australia because of the carbon tax? Is this just another example of Australian jobs going offshore with no impact whatsoever on the reduction of carbon emissions?
