Rhett Russell, 52, pleaded guilty to four counts of criminal damage after attending Wodonga sites including Hartwig Road and Awburn Street between June and August 2019.

Magistrate Ian Watkins had earlier sought clarification from the prosecution about the extent of damage caused by the Wodonga man.

Wodonga Magistrates Court heard this week that due to difficulties in quantifying the damage caused, the prosecution would not seek restitution but noted NBN may consider options.

However, NBN made it clear that, particularly in relation to the Awburn Street offence, Russell had been sent there to complete a connection and not to fix a fault, so there would have been no need to use a knife or cut any wires.

Defence lawyer Chirag Patel said Russell's explanation was that in order to complete a connection, he would need to cut the old wires that were in the way.

"In so doing, he's obviously cut more wires than he ought to have," he said.

"He conceded this was more than just an accident, he was acting recklessly in his work practices."

Mr Patel also raised his client's CFA involvement.

Mr Watkins convicted Russell of the charges, placed him on a good behaviour bond and ordered that he pay $2500 to the court fund.

"On four separate occasions you severed wires at various NBN sites throughout Wodonga," he said.

"The informant is of the view that it had to be a deliberate act and you're submitting to the court that it was reckless. Either way ... the damage caused significant inconvenience to the people of Wodonga who were unable to use the internet."
