An independent review will be launched into Queensland Fire and Emergency Services workforce complaints after allegations of harassment and discrimination.
Fire and Disaster Recovery Minister Nikki Boyd said on Friday the six-month probe into QFES's complaints management system would start in February.
The announcement came days after Rural Fire Brigades Association Queensland general manager Justin Choveaux posted an open letter to Premier Steven Miles, complaining of QFES's "ongoing toxic culture".
"I have been recently contacted by multiple QFES paid staff with complaints of systematic contempt, bullying, harassment and discrimination based primarily on gender, professional backgrounds and progressive leadership," he wrote.
Mr Choveaux called for an "immediate and independent investigation", saying staff had no faith in QFES fairly investigating the claims due to systemic discrimination.
Ms Boyd, who did not address the open letter when she announced the review on Friday, said the six-month probe had been planned since late last year.
"This has been planned for some time but I think it is timely to have an external and independent review," she said.
"The safety and wellbeing of staff and volunteers in the service is our primary objective which is why we welcome this review into the department."
Mr Choveaux said in his letter the state government had commissioned an independent review in October 2014 into the handling of a QFES sexual harassment complaint.
He said the report found QFES failed to respond effectively to the complaint and identified systematic organisational problems that limited its ability to respond appropriately.
Mr Choveaux said a decade later, the situation had not improved.
"Ten years on and the Fire and Rescue Service and QFES ... is populated with the same senior fire bureaucrats in Brisbane with new business cards and the ongoing toxic culture is becoming worse," he wrote.
