Mr Stewart will end his seven-year tenure at the top of Queensland Police on July 7, after which Ms Carroll will become the first woman to lead the state's police service.

The new QFES Commissioner can expect a salary package of about $400,000, and will oversee a combination of paid staff and volunteers who respond to some of the state's biggest emergencies.
