Order! The Minister for Infrastructure, Transport, Regional Development and Local Government and the Leader of the Opposition will cease their discussion across the chamber. I want to hear the member for Lingiari in silence. I want to be clear with everyone that, when members are asking questions, out of courtesy and respect I want the chamber to listen to the question. Equally so, when the minister approaches the dispatch box they're to be addressed with respect and courtesy as well. I give the call to the member for Lingiari.
