Senator MARIELLE SMITH (South Australia) (14:08): My question is to the Minister representing the Prime Minister, Minister Wong. In my state of South Australia, parents often tell me how concerned they are over social media and the risk of harm that it's presenting to their children. South Australia has, of course, introduced landmark new laws to protect children and to support parents. Can the minister explain what the Albanese government is doing alongside the South Australian government to keep children safe online? Senator McKenzie interjecting— The PRESIDENT: Order! Just a moment, Senator Wong. Senator McKenzie, you need to cover that shirt or remove it. Senator McKenzie: You want me to take it off? The PRESIDENT: Senator McKenzie, it's a prop. Cover it or remove yourself from the chamber. Honourable senators interjecting— The PRESIDENT: Order! Senator McKenzie, your shirt is still visible. You need to turn it inside out or leave the chamber. Honourable senators interjecting— The PRESIDENT: Order! Senator McKenzie and all the senators who think this is funny: props are not allowed in this chamber, nor are T-shirts or other paraphernalia that have words which are clearly visible. Senator McKenzie, I've given you a choice. Senator McKenzie interjecting— The PRESIDENT: No, it's not okay. Senator McKenzie, unless you intend, for the whole of question time, to sit there and hold the blazer, that is not appropriate. I've given you an option. Senator McKenzie interjecting— The PRESIDENT: No, I've given you an option. Minister Wong.
