The Senator Julian McGauran in the Australian Senate had made an "unseemly" gesture across the floor of the Senate whilst it was in session on August 11, apparently as a result of interjections about a division taking place.  Whilst this was not immediately debated, Senator Bob Brown had asked the Acting Deputy President of the Senate to look into the matter. Later the President of the Senate ruled that the gesture was "unseemly but not obscene."
