Speaker Sue Hickey does away with convention and signals new way of running Parliament

She also did away with parliamentary convention by not allowing the Opposition leader to ask the first two questions during Question Time.

Before another rowdy sitting, Ms Hickey told MPs she was sick of their behaviour.

"The inappropriate yelling, nasty insinuations and some instances of very aggressive behaviour would not be tolerated in any modern workplace," she said.

"I consider it a form of bullying.

"From this day forward, I remind you all that as leaders of the community and role models for our youngsters who visit parliament we will argue the facts of the debate before us as professional politicians.

"Any failure to adhere to respectful behaviour will be given up to three warnings only because it has been accepted practice of the House and certainly not because I think it should be necessary to remind adults on how to behave three times during question time or for the day's duration."

She said as a relatively new Speaker she had tried being "tolerant and friendly".

"That approach has not been appreciated. I will now enforce the Standing Orders for good behaviour without fear or favour because the public expect us to get on with the serious job of governing and not to resort to insults and petty political arguments.

"Be assured I will no longer tolerate any backchatting of the Speaker and offenders may be asked to leave the Chamber without the three warnings."

When Ms White challenged Ms Hickey's decision to give second question to Liberal Braddon member Joan Rylah Ms Hickey told her: "That might be the convention but in this case, I heard Mrs Rylah first.

"I ask you to sit down and stop causing trouble.

"I am getting tired of these frivolous points of order."

She also asked Ms White "have you heard of Speaker's precedent?"

Ms Hickey repeatedly warned Labor MPs they would be ejected and sent Ms White out for an hour as Question Time ended.

Greens leader Cassy O'Connor defended Ms Hickey's calls.

"It's really important in Parliament that you try to maintain good relations with people so you can get stuff done," she said.

Ms O'Connor believes Ms Hickey was frustrated at Labor's behaviour.

"Labor keeps trying to use her interactions with the Liberal Party for political purposes. They came into the house this week and made it all about the politics, rather than the policy, and that's because they don't actually have any policies," she said.

Ms White was unfazed and said outside parliament that she would not apologise for trying to hold the government to account.

"It's clear that this week Sue Hickey likes the government, last week she didn't like the government," Ms White mused.

"She's clearly very friendly with the government but I will hold the government to account on unemployment when he have the highest unemployment rate in the country and health."
