Jason Szerszyn, 30, pleaded guilty in Warrnambool Magistrates Court this week to burglary and other offences.

The court heard he and a co-accused attended a property in Warrnambool's Foster Street in January and entered through a broken glass panel.

They stole a mirror, decorative items and two sewing machines, including one considered antique.

The court heard the co-accused returned to the property numerous times and stole additional items, which he sold to unknown people in Wanstead Street in order to buy drugs.

Then on January 5, 2019, Szerszyn posted the two sewing machines on Facebook Group Warrnambool Buy Swap and Sell.

He advertised the antique sewing machine for $250 and the second machine for $100.

The man used a Facebook account in his name and with his photograph.

Szerszyn was arrested. During an interview he told police he attended the Foster Street address and entered through a smashed window.

He said he entered the house because he was "curious" and remained there for about five minutes.

He said he only attended the house on one occasion.

Legal Aid lawyer Emma Tinney said the co-accused was placed on a community corrections order for 12 months.

"The co-accused has a more extensive criminal record, having previously serving terms of imprisonment as early as a year prior to the current sentence," she said.

Ms Tinney said Szerszyn had "extremely limited" priors, was cooperative with police and was a very low risk of reoffending.

Magistrate Franz Holzer said the man should "keep away from undesirable influences".

"That is a significant protective factor in and of itself," he said.

Szerszyn was convicted and fined $1200.
