I will rule on the point of order. Senator Di Natale, I have called the Senate to order. I've addressed the matter raised by Senator Macdonald. I asked for a question to start earlier before because the noise level was so high and no-one could hear it. This was about one interjection. I could hear the question, as could many others, but I was being consistent in my rulings to ensure a senator was heard in silence. I ask you to continue your question.
