Ms Cliona Richardson:

We also have to get orders in relation to ensuring any evidence can be extracted. They do not volunteer that. However, it should be known that it is up to the social media companies themselves as to whether they assess the information that is online and it is up to them to take it down. We cannot force them. As I said, there is no compellability if there is a criminal act involved, so they cannot take it down. Again, they assess what they see. We can make a complaint to them about it, but it is up to the companies.
