A Farmborough Heights pensioner has admitted breaching child protection laws after failing to declare his Facebook account to police.
Oskar Weidl, 80, was convicted of child sex charges in 2010 and sentenced to jail time.
As part of his conviction, he was put on the Child Protection Register for 15 years.
When released from jail in late 2014, Weidl reported to Lake Illawarra Police Station under the conditions of his registration.
He was explained his obligations to comply with the register's conditions, including yearly reporting in which he had to advise police of any social media accounts he set up or regularly used.
Weidl reported to police each year, however when detectives carried out a routine inspection at his home in April this year, they discovered he was operating an undeclared Facebook account.
When questioned, Wiedl told police he only used the account to communicate with family members and did not realise he had to report it.
He was issued with a court attendance notice for a charge of failing to comply with his reporting obligations.
Weidl pleaded guilty to the charge in Wollongong Local Court on Tuesday, with defence lawyer Patrick Schmidt saying his client had accepted responsibility for the breach and was sorry for his action.
"He was completely compliant with police when they did their check," Mr Schmidt said.
Magistrate Mark Douglass convicted Weidl but released him on an 18-month community corrections order.
"I find this was an oversight - there was nothing malicious or suspicious in relation to the device being used to commit further offences," he said.
