Debates between MPs in Queensland's parliament will be capped and committee meetings moved from Wednesday to Monday after a vote in favour of changes to sessional orders.
Reforms that include scrapping some private members' motions and limiting parliamentary proceedings to 7.30pm on Tuesdays and Wednesdays and 6.30pm on Thursdays were passed with a majority vote in state parliament on Thursday.
It will also mean committee meetings are moved from Wednesday to Monday at the ire of some regional MPs who will now have to travel from far-flung electorates on a Sunday.
Members will still have the option to move a motion allowing sittings to run longer.
The Labor government argued the changes would establish a more "family friendly" environment for MPs and parliamentary staff.
"The proposed sessional orders for the 56th parliament aims to bring the Queensland parliament in line with many other jurisdictions across this country by streamlining the work of the house and setting sensible working hours," Attorney-General Yvette D'Ath said.
Meanwhile, Liberal National Party leader Deb Frecklington slammed the changes as an attempt by the state government to stifle accountability.
"They are shutting down the opposition and the crossbench's ability to hold this government to account in this house exactly as we are put here by our electorates to do," she said.
