Senator PATRICK (South Australia) (17:50): In my short time in this place I have enjoyed working with Senator Rhiannon. I haven't always agreed with her positions, but she's put her case politely and forcefully. I admire the manner in which she has progressed the things that she cares about. I've also liked her approach to committee work and I have actually learnt something from her, and I'm grateful for that. On behalf of Centre Alliance, I thank you and I wish you well in the future. The DEPUTY PRESIDENT: That concludes the valedictory statements for Senator Rhiannon.
