Queensland will get its first female Police Commissioner after Katarina Carroll was announced as the new head of the police service.

Ms Carroll is the current commissioner of the Queensland Fire and Emergency Services (QFES) and will take over the top job in the Queensland Police Service (QPS) in July, following the retirement of current Commissioner Ian Stewart.

She is the first woman to lead the state's police service in its 155-year history.

"It is a privilege and honour to be chosen as the next commissioner," Ms Carroll said.

"I'll be working hard over the next five years to make sure I keep this wonderful state safe."

Ms Carroll started her career with the Queensland Police Service in 1983 and rose through the ranks to hold several positions, including Assistant Commissioner (Far North) in 2010.

At the time, she was one of only two women at the rank.

She was also in charge of security and planning operations at the G20 summit in Brisbane in 2014, before spending four years at the helm of QFES.

Ms Carroll said she was ready for a new challenge.

"Certainly I do have plans that I'd like to unveil with my organisation … and a lot of that sits around prevention — together working with community and other agencies at a local level, place-based — but also to take that tough stance on serious crime," Ms Carroll said.

Premier Annastacia Palaszczuk said Ms Carroll was an outstanding choice for the position, selected from a handful of other hopefuls.

"Commissioner Carroll was the best person for the job but I'm also delighted she'll be the first female police commissioner Queensland has had," Ms Palaszczuk said.

"This sends a strong message to young girls that you can do anything in this state.

"She has worn the uniforms of two branches of our emergency services and stood by us in our toughest times, including cyclones Debbie and Marcia, not to mention the 2018 bushfires."

In 2013, Ms Carroll recalled that in her first year in uniform, three decades earlier, her senior sergeant told her that women had no place in the Queensland Police Service.

She has two children.
