The Queensland Parliament may not sit again before September after the government rushed through an emergency motion late on Wednesday night.

Attorney-General Yvette D'Ath introduced changes to sessional orders to allow Speaker Curtis Pitt to alter the Parliament's sitting calendar.

Ms D'Ath said the Parliament intended to reconvene on March 31, but the new laws would give the Speaker the power to suspend sittings until September 17.

"This should be used in very extreme, rare circumstances," she said.
