Thank you, Mr Acting Deputy President. Senator Macdonald raises one example, but perhaps I could give him another. Senator Bernardi, Senator Sinodinos's predecessor as shadow parliamentary secretary to the Leader of the Opposition, resigned from this position after admitting that he had failed to meet the standards of conduct expected of those holding high public office.

The circumstances of the Senator Sinodinos's confession are very concerning and they leave several important questions unanswered. Senator Brandis, I am not seeking to answer those questions or, indeed, imply what the answer may be. I am raising before the Senate that there are many unanswered questions.
