A 38-year-old senior school teacher from Central Queensland is among six men charged with child sex offences in the state after a nationally co-ordinated operation.

Nine search warrants were carried out across Queensland as part of the month-long action targeting "high-threat" online child sex offenders that saw 22 people charged with 56 offences nationwide.

Officers from the State Crime Command's Child Abuse and Sexual Crime Unit, along with regional Child Protection and Investigations Units, were involved in the operation – the first co-ordinated by the Australian Centre to Counter Child Exploitation (ACCCE).

Material seized will be examined to help identify child victims as part of investigations.
