The Queensland Government is to wind back “harsh and unfair” changes to WorkCover legislation made under former premier Campbell Newman.

Treasurer and Employment and Industrial Relations Minister Curtis Pitt says Premier Annastacia Palaszczuk, who led Labor to victory in January, is “acting quickly and decisively to right the wrongs of the Newman era”.

Under changes introduced in October 2013 workers must have impairments of more than 5% to lodge common law damages claims, and must prove psychiatric and psychological disorders are work-related.

The Liberal National Party amendments also require insurers to ensure common law claimants have access to return-to-work programs.

“The harsh and unfair common law amendments introduced… by the previous LNP Government are only now starting to flow through in the claims data,” Mr Pitt said.

“The unfairness of the… scheme isn’t being seen yet, because many claims haven’t been lodged.”

Mr Pitt says premiums for the no-fault workers’ compensation scheme will remain at an average of about 1.2% of wages next financial year.

Other states that have announced premiums for next financial year are Victoria (1.272%), WA (1.483%) and SA (1.95%).
