Mr DUTTON (Dickson—Leader of the Opposition) (14:58): My question is to the Deputy Prime Minister, and I refer to the Deputy Prime Minister's earlier answer in confirmation that waste from the nuclear propulsion system will be stored on the submarine in the reactor for many years. Can the Deputy Prime Minister confirm that it is safe for the submariners to be in that environment? Ms Catherine King: It's still being used! The SPEAKER: Order! The Minister for Home Affairs and the minister for infrastructure. If the minister for infrastructure and transport continues to interject, she will be warned. I want the House to come to order. The Leader of the Opposition was heard in silence. This continual interjecting on my right has to stop; otherwise, I'll be issuing a general warning to members on my right.
