Senate president Sue Lines has blasted the conduct of her colleagues and implored party leaders to drive standards in tackling "out-of-line" behaviour.
Giving evidence to a parliamentary committee, Senator Lines said she'd be open to changing standing orders and procedures in the upper house to ensure inappropriate behaviour could be managed.
"This is something we need to come to terms with, I don't think as the president I can keep parroting 'behaviour needs to be respectful' because then that statement in and of itself starts to lose value," he said.
