Pedophile ring bust linked to arrest of A Current Affair's Ben McCormack

The arrest of A Current Affair reporter Ben McCormack has allegedly been linked to a pedophile ring membership list discovered by police in Western Australia.

Police were investigating a suspected child rapist when they uncovered phone records, computer files and other information about the ring, which allegedly included school teachers and Mr McCormack, 9NEWS understands.

The information was reportedly shared with police across the country, and led to the arrest of a West Australian Catholic primary school teacher.

The West Australian investigation began in February, when the alleged rapist was arrested and charged with 35 offences.

The Daily Telegraph reports a Queensland teacher was also arrested in the operation.

Mr McCormack, 42, was arrested in Sydney on April 6 and has been charged with two counts of using a carriage service for child pornography material.

New South Wales police allege he engaged in explicit conversations about children with an adult male and discussed child pornography.

Mr McCormack was released on bail and was later admitted to a private hospital, where he continues to receive treatment.

His lawyer Sam Macedone said the charges against him have "nothing to do with the usual child pornography".

"None of the charges that have been levelled against him involves pictures or explicit details of young kids," he said.

"It's got nothing to do with the usual child pornography where you've got young children being photographed or in a video or anything like that. It's nothing more than a discussion and that's all there is."

Mr McCormack's case is scheduled to return to court on July 4.
