The end of Queensland’s Crime and Misconduct Commission will herald a raft of new legislative changes in the state from July 1.

Queensland’s corruption watchdog the Crime and Misconduct Commission starts its transformation from Tuesday.

The CMC will be renamed the Crime and Corruption Commission and will no longer investigate minor misconduct allegations.

The overhaul has sparked controversy and public debate, but without it, Attorney-General Jarrod Bleijie says the organisation would have become snowed under and run itself into the ground.

“The new Crime and Corruption Commission will be a modern, unmuzzled watchdog that will fearlessly and effectively tackle serious crime and corruption in Queensland, something the old CMC was unable to do,” Mr Bleijie told AAP.

The opposition vehemently argued the laws could open the state to more misconduct and corruption.

The legislation also allows acting chair Ken Levy, who is under investigation for misleading parliament, to remain in the role until the end of October.

A chief executive officer will also be hired for the first time.

The new financial year will also see a number of other changes throughout government departments.

The Health Ombudsman will replace the Health Quality and Complaints Commission after a report found it was taking too long to deal with complaints.

Also, a number of the state’s 16 local health boards will gain control of their buildings and staff, possibly leading to some job losses in Queensland Health’s central bureaucracy.

In Education, the Queensland Studies Authority will be replaced by the Queensland Curriculum and Assessment Authority, and an ongoing review into senior assessment and tertiary acceptance is ongoing.

In the environment department, a new environment offset policy will be adopted which reduces costs and the regulatory burden for developers, while avoiding duplication across all levels of government.

There will also be major reforms to Queensland’s leasehold land system.

Rolling term lease arrangements for agriculture, grazing and pastoral purposes will be introduced to cut red tape.
