Senator GALLAGHER (Australian Capital Territory—Manager of Opposition Business in the Senate) (16:43): My understanding on the guidelines and procedures around that is that it's the possession of the photo as opposed to the publication of the photo that might be relevant here, in which case— The PRESIDENT: I think it's the publication, off the top of my head. I would have to check the rules. Senator GALLAGHER: Could you have a look at the difference between the two? The PRESIDENT: Yes. I believe the rules go to the publication of photos, primarily. I'm going to look at the Clerk. Yes. I might say that it wouldn't be the first time I've seen senators pull out a phone in a way that might make me suspect they've taken a photo. The rules, in my view, have always related to the publication of such photos, whether that be on social media or otherwise. If I'm wrong, I'll come back to the chamber.
