Mr TEHAN (Wannon) (15:26): I have a question of you, Mr Speaker, where you might be able to assist. During question time, the Minister for Defence Industry misled the House. He said that aluminium rusts. That is just not true. I have an aluminium smelter in my electorate. I think that it would help the House—and I don't want to take it any further than necessary—if he could come back and correct the record that aluminium doesn't actually rust.
