On a point of order, Mr Acting Deputy President, the level of interjection and noise coming from those opposite has gone well beyond what is reasonable and tolerated in this chamber. Senator Abetz was listened to in almost total silence, but Senator Brandis and others are continuing a barrage of interjections. Not only is it unparliamentary and rude, it is also against the standing orders, and I would ask you to bring the chamber to some level of order.
