The Speaker is supreme, every member should follow the following rules
Speaker calls a member, those who wish to be called should stand at the end of a speech or catch his eye, I guess Barry can be the speaker. Although if two are debating, do not wait to be called as it would disrupt flow
Never address the member, address the speaker, do not call any member by their name etc
Do not cross the white line in front of the bench
Do not rise while the Speaker is standing
Do not insult any members
