Senator FIFIELD (Victoria—Manager of Government Business in the Senate and Assistant Minister for Social Services) (15:06): Under indulgence, can I acknowledge that today is the last day in this building of the Senate PLO, Michelle Rak. We all acknowledge the important role that the Senate PLO plays in this place in what is an interesting professional environment for a public servant. Can I thank her on behalf of the government for her service to the Australian parliament, and acknowledge Susan Cattermole will be starting as her replacement.
