A Mayfield West man is due to face court next month after a 6 month investigation into online child exploitation.
Detectives from the Child Abuse and Sex Crimes Squad's Child Exploitation Internet Unit commenced an investigation in July 2018 following a referral from police in the United Kingdom.
During the covert investigation it's alleged the man believed he was speaking with two girls aged 10 and 12, and engaged them in sexually explicit conversations.
Detectives from Strike Force Trawler swooped on the man's home on Friday morning and arrested the 39-year-old.
They also seized a mobile phone.
He's been charged with two counts of use carriage service to send indecent material to person under 16 and granted strict conditional bail to appear at Newcastle Local Court on Thursday 31 January 2019.
