A former football coach who committed sexual offences against three boys "deceived himself" in order to "minimise his actions", an ACT Supreme Court judge says.
Stephen James Porter, 51, has pleaded guilty to child sexual offences but is yet to be formally sentenced.
Last year, he unusually asked the ACT Supreme Court to send him to jail, ahead of his inevitable prison term.
Porter's sentencing has been delayed because although he admitted to the charges, he disputed some of the facts in the case, relating to the third victim.
Specifically, Porter said the offences against the boy happened between 14 and 15 times.
Though the victim said there had been between 35 and 45 incidents.
Today, Supreme Court Justice Chrissa Loukas-Karlsson delivered her finding, accepting the victim's account.
During the hearing, the court was told that the first incident had occurred after a private training session when the boy was about 12.
The court also heard that Porter had befriended the boy's family, often having dinner with them and sometimes staying over on a trundle bed in the boy's room.
'Grave reservations about the offender's evidence'
A key issue in the case concerned the boy's claim about numerous assaults in the family's home.
Porter told the court the door was open, and the house was small so if anything had happened others were likely to have heard it.
He also said he had only stayed over at the boy's home about 15 times over three consecutive summers.
But Justice Loukas-Karlsson found that differed from evidence from others.
The boy's mother also said they asked for the door to be open, but sometimes it was closed.
"In my view, the offender's evidence as to how many times he stayed at the complainant's house is an attempt to minimise the number of opportunities he had to engage in sexual activity," Justice Loukas-Karlsson said.
Justice Loukas-Karlsson also noted inconsistencies between Porter's account to police and the evidence he gave in court.
"I have grave reservations about the offender's evidence," Justice Loukas-Karlsson said.
No date has been set for sentencing.
