Senator BIRMINGHAM (South Australia) (18:18): I appreciate, as Senator Xenophon said in response to Senator Milne's comments, that Senator Feeney is even less of an expert on this legislation than I am, and I certainly do not profess to be one. My colleague who sits to my left is more knowledgeable than I. It is not terribly helpful to the conduct of debate when we are simply referred to statements in the other place or the like. I do not know where Senator Ludwig is at present. Frankly, if in response to broad questions like the one I may have just asked or more detailed questions like the ones that Senator Xenophon was asking we cannot get clear answers on the record, we should honestly move onto something that we can deal with today and we can all be back here bright eyed and bushy tailed in the morning.
