A Queensland teacher charged as part of a major paedophile bust has committed suicide, while another is in hospital after a failed attempt to take his life.

More than 90 men across Australia have been arrested and hundreds more remain under suspicion as part of the six-month Operation Centurion.

One of the men arrested, a 59-year-old Gold Coast teacher, has committed suicide after being charged over the bust, News Ltd reported.

A second Queensland teacher, 48, is recovering in hospital after a failed suicide attempt, News Ltd said.

About 1500 people or individual computers in Australia have been identified in the investigation, which is part of a wider Interpol investigation involving 170 countries.

A policeman, four Queensland teachers and a West Australian sports administrator were among those arrested or summonsed in Australia as a result of the six-month operation.
