Controversial laws to change Queensland's workers compensation scheme have been passed after passionate debate in Parliament overnight.

The legislation limits the injuries for which workers can sue employers, angering unions and lawyers.

Labor and the minor parties opposed the laws.

The Government drew more criticism when it guillotined parliamentary debate on the laws at midnight (AEST).

Independent MP Liz Cunningham says details escaped scrutiny.

"It's a very emotive Bill and one that we haven't had a lot of time to either digest or to properly debate," she said.

She became emotional after recounting her family's experience when her father was hurt on the job, telling the House the scheme should not have been changed.

"It will disadvantage families at a time when they are most vulnerable because of injuries and most vulnerable to family disconnect and most vulnerable to financial hardship," she said.

"I think it is unnecessary and reprehensible."

The Opposition says some Government MPs will lose their seats because of changes to workers compensation laws.

Labor MP Bill Byrne says the laws will change votes.

"LNP members will lose their seats over this issue," he said.

However, Attorney-General Jarrod Bleijie says public consensus was impossible.

"We haven't pleased the business community - they wanted more," he said.

"We haven't pleased lawyers - they wanted less."

He moved an amendment to give injured workers an extra option to appeal medical assessments.

Changes will 'benefit the rural sector'

Meanwhile, the Queensland Farmers Federation (QFF) has welcomed the State Government's changes to the workers compensation scheme.

QFF chief executive officer Dan Galligan says farmers have faced rising premiums for the past decade.

He says some of the changes to Queensland's WorkCover compensation scheme will benefit the rural sector.

Mr Galligan says the Government is on the right track in reducing to reduce premiums for employers.

"One of the reasons why premiums in workers compensation continue to rise, is because of the ongoing struggling in trying to manage safety in rural businesses," he said.

"They are inheritably a risky place to work, so we want to see a balance between profitable workers compensation scheme.

"But we would like to see some of that money go back into rural businesses, particularly to assist us in working with them to reduce the risks in the workplace."

Mr Galligan says one of the proposed changes would give farmers access to the claim history of job applicants.

"That should be a benefit to employers, particularly in rural business, as many employees travel the country working in agriculture businesses and sometimes we do get caught with people with pre-existing conditions that they don't make clear when they're employed," he said.

"That change will be a positive step for an employer as well."
