Mr ALBANESE (Grayndler—Prime Minister) (15:38): on indulgence—I would like to pay a short tribute to Simon Birmingham following his announcement of his retirement. He's someone who's been here since 2007. He has served as finance minister and trade minister. I've dealt with him as the Leader of the Opposition in the Senate. He's someone who has very broad respect right across the parliament; he certainly has my personal respect. He also has been into my office on a few occasions. He's someone of integrity who is easy to deal with and who gets things done. It is understandable that he's made this decision. I wish all the very best to Simon, Courtney and their family.
