Speaker Fiona Simpson has defended the decision to have a union organiser removed from parliamentary grounds.

Electrical Trades Union state organiser Stuart Traill had organised a press conference outside the parliamentary annexe to respond to the state government's budget on Wednesday morning, but was escorted off the grounds after confronting LNP MPs Vaughan Johnson and David Kempton.

"The Queensland parliament is no longer the people's house," Mr Traill told media.

But Ms Simpson said parliament security had acted appropriately.

"This occurred because the person in question was harassing members of parliament on the parliamentary precinct," Ms Simpson told the House.

"Such behaviour is unacceptable and I completely support the actions of parliamentary security officers for directing the person to leave the precinct.

"Nobody has the right to come on to the precinct and act in a bullying and aggressive manner, whether that is harassment directed towards a Member of Parliament, a staff member or a member of the public.

"The fact is that a large number of media interviews were conducted on the precinct yesterday by stakeholders with a variety of viewpoints, and all were held without incident.

"It is regrettable that today the person in question did not conduct himself within the standard of behaviour applied to all people on the precinct and his removal was the consequence of his poor behaviour."

Standing outside parliament, Mr Traill said the union would begin its anti-privatisation campaign in earnest.

"We have thousands of electricity workers that today are concerned about their job security and future," he said.
