Katherine McGrath, "Thank you very much for your presentation. It's a great opportunity to put a spotlight on these issues, as you've said. I wanted to touch on what you just mentioned there about responses, because I think I would like to know and a lot of people would like to know, what is going on in Australia right now with perpetrators? What is the range? You've obviously had probably the most latest briefing from police? So, could you give us an idea of what is happening there? And also how the social media operators are responding, and do you see some change?
