Timothy Luke Doyle, 26, of Graham Street, appeared before Magistrate Georgina Darcy on Thursday October 22.

Doyle was not required to appear in court. Magistrate Darcy refused Doyle bail.

Doyle was charged with a total of 300 charges, relating to alleged incidents from June 2011 through to June 2020.

These include, sexual intercourse with child under the age of 10 years; produce child abuse material; use child under 14 years to make child abuse material; commit act of indecency with person aged under 16 years; possess/control child abuse material using carriage service; indecent assault of person under 16 years; sexual intercourse with child under 10 years; intentionally sexual touch child under 10 years; sexual intercourse with child under the age of 14 years; incite person under 16 years to commit an act of indecency; aggravated indecent assault, victim under authority; indecent assault of a person under 16 years; use carriage service to publish/transmit child abuse; use carriage service to groom under 16 year old for sex.

Those charges relate to alleged incidents at Wingham, Old Bar and Kendall on February 27, 2018, January 26, 2018 and June 4, 2020.

The children were aged between four and six.

Prosecutor Kilkeary told the court there were still some outstanding details required to be presented to the court.

Magistrate Darcy noted that there were "new charges against Doyle in this matter" yet to be presented.

Doyle is next listed to appear in the Port Macquarie Local Court on November 19.

Court documents indicate Doyle allegedly video recorded a child performing a sex act on two occasions - one of these was allegedly at a Mid-North Coast childcare centre.

Doyle was charged following an Australian Federal Police-led investigation into a domestic online network of alleged child sex offenders.

Doyle was charged as part of Operation Arkstone, which was launched in early 2020 after a tip-off from the United States' National Centre for Missing and Exploited Children to the AFP's Australian Centre to Counter Child Exploitation (ACCCE).

NSW Police media have confirmed the arrests are in not related to William Tyrrell.

Police allege that analysis of evidence seized during each arrest helped identify other suspected offenders.

AFP assistant commissioner for ACCCE and northern command Lesa Gale said police believe they have uncovered one of the biggest domestic child exploitation networks in recent times.

She said police will allege in court that some of the accused men had sexually abused children known to them and recorded videos and photographs to share with others online.
