Mr President, on a point of order: I would invite you to write to the Leader of the Opposition, Mr Shorten, in the other place to indicate the behaviour of his frontbench during question time and that, unless there is some sort of discipline in this place, there will be the farcical situation that we just witnessed egged on by the leader of the opposition in this place. If leadership, Mr President, cannot be shown in this place by Senator Wong, Mr Shorten, clearly, will need to step in.
