In a question time like no other, Ms Hickey threatened MPs with expulsion for raising the issue of relevance when government ministers were answering their questions.

Tamanian political analyst Professor Richard Herr said Ms Hickey seemed to be affected by "the tensions around Madeleine Ogilvie".

"She also had a Samoan delegation watching in Parliament and in that sense there was more theatre in question time and it was more unusual and less predictable than usual," Professor Herr said.

"The question on relevance has always been the speaker's call but you are not going to get relevance in minister's answers by chucking out the opposition parties.

"The ministers need to be put in their place."

Professor Herr said in New Zealand questions were submitted to the speaker four hours before question time and it seemed to work well.

"The minister has four hours to prepare an answer but the the opposition can ask supplementary questions," he said.

Ms Hickey said from Thursday "frivolous points of order will be given a warning."

She warned several Labor MPs and ejected Greens leader Cassy O'Connor and her colleague Rosalie Woodruff.

During a question, Ms O'Connor said it was important "under standing order 45, that the Treasurer addresses the question which relates to tax negotiations with the Federal Group".

Ms Hickey responded: "As you know, it is not a point of order. I am considering frivolous points of order, because everyone here is quite experienced, as a warning. So, I am afraid I have to give you a warning, Ms O'Connor.

"It is just becoming a habit to distract and waste the taxpayers' money."

Ms O'Connor said the ruling was "unprecedented".

Ms Hickey said she did not care.

"This is the thing: we have had nothing but frivolous points of order to distract from sensible debate, so it stops as of today," she said.

Ms Hickey suggested members raise the standing order on relevance with the Standing Orders Committee but there are no Greens on the committee.
