"Interjections during question time have been out of control for some time," Dr Bonham said.

"As soon as the Speaker starts talking there seems to be a wall of noise and you can't even hear what people are interjecting.

"I don't think that it presents a very good public image of the Parliament."

Ms Hickey said she would be cracking down on behavior in the chamber following a row between herself and Labor deputy leader Michelle O'Byrne on Wednesday over the use of the term 'ladylike'.

"The public expect us to get on with the serious job of governing and not to resort to insults and petty political arguments," Ms Hickey told the house on Thursday.

"Any failure to adhere to respectful behaviour will be given up to three warnings only because it has been accepted practice of the house."

The Speaker handed out numerous warnings to Labor and Greens members and ejected Labor leader Rebecca White after telling her to "sit down and stop causing trouble."

Ms Hickey had to repeatedly remind members of the house rules as members were instead interjecting via points of order.

"I am getting tired of these frivolous points of order," she said.

Ms Hickey also caused a stir this week by again voting against her own party, siding with Labor and the Greens on a bill that sought to introduce minimum mandatory sentences for serious assaults on select frontline workers.

This is the second time Ms Hickey has voted against minimum mandatory sentences in recent months, having sided with the opposition and the Greens on a bill which would guarantee jail sentences for serious child sex offenders in May.

Health Minister Sarah Courtney cited Labor's stubborn refusal to support mandatory minimum sentences for serious offences as the reason the bill failed, however it was Ms Hickey's tie-breaking vote which resulted in the legislation not passing the house.

Dr Bonham said it was interesting Ms Hickey's vote on the bill was not influenced by her stoush with Labor.

"After some days where she was quite at odds with [Labor], she then turns around and votes down a piece of policy of which government has a mandate," Dr Bonham said.

"It does suggest that she is going to keep behaving independently and that she is not going to let any conflicts with Labor put her off doing that."
