Senator IAN MACDONALD (Queensland) (18:37): I just wanted to, again, ever so briefly associate myself with the fine words that have been said about my colleagues Senator Williams and Senator Leyonhjelm. Both are exceptional men, as we've heard this afternoon, but those of us who've been here for a while with them knew that without having to hear it today. The number of people that Wacka had here is testament to the very high regard he is held in his community. The two of them are perhaps two of the most—apart from you and me, Mr Acting Deputy President Marshall!—genuine members of parliament that I've ever had the pleasure to be associated with. Both are very true to their causes. Both have a commitment. I just want to put on record, as I've done privately and will do privately, my best wishes to both of them and my regards to their respective spouses. I wish them both all the very best in the future.
