Senator CASH (Western Australia—Minister for Jobs and Innovation) (14:57): Again, I've answered this at estimates several times. Senator Cameron, you will be aware that the AFP Commissioner has claimed public interest immunity in relation to this, and it was accepted by the committee. Senator Cameron interjecting— Senator CASH: Again, you can throw as much mud as you like, Senator Cameron, but the heart of this is all about the AWU refusing to provide documents that showed that donations made by Mr Shorten were properly authorised. The PRESIDENT: Senator Wong on a point of order. Senator Wong: Yes, direct relevance—no preamble, one question: has the minister been interviewed by the AFP? The PRESIDENT: Senator Cash has concluded her answer. Senator Cameron interjecting— Honourable senators interjecting— The PRESIDENT: Order! Senator Cameron! I will again insist: I've called numerous senators around the chamber to order while questions have been asked so I may hear them.
