Simon John Sedgley, 46, of Morack Avenue in Warrnambool, pleaded guilty in the Warrnambool Magistrates Court to aggravated burglary, theft, assault with a weapon wilful damage and breaching an intervention order.

He handed himself into police last year and admitted his involvement in the aggravated burglary to, "get it off my chest".

Police said Sedgley and co-accused Jordan Brown visited a house in Yangery on the morning of February 12 last year. 

Sedgley thought the house would contain cash because the occupant was a gambler.

The pair concealed their identities with balaclavas and armed themselves with a steel pole.

They entered the house through a sliding glass door while the 64-year-old occupant was asleep. 

Brown went into the bedroom, demanded cash and assaulted the man while he was in bed. 

The man told them the cash was hidden in a vehicle parked at the rear of the property and he escaped through a window and ran to a neighbour’s house while the intruders followed his instruction. 

Sedgley and Brown stole receipts and a cheque book. The victim suffered cuts to his head and arms.

The next day, Brown tried to cash a cheque for $2760 but a bank teller recognised the victim's name, knew the cheque book was cancelled and called police. 

Brown, then 21, of Clifton Street in Warrnambool, pleaded guilty in July last year. He was jailed for 12 months with an 18-month corrections order to follow.

On Friday, Sedgley also pleaded guilty to breaching an intervention order after he broke a window at his girlfriend's home in September. 

She reported the matter to police to avoid paying $116 to repair the window. 

Sedgley said the woman invited him for drinks but they later argued, she spat in his face and he “pushed the window” because he was angry and frustrated.

The magistrate said acknowledged Sedgley’s guilty plea but called for more information about the defendant's mental health before handing down a sentence.

He said the serious offending would regularly result in a prison term.

He said there was a significant difference between the actions of Sedgley and Brown, because Brown had assaulted the victim and caused injuries.

The magistrate said their penalties would be different.

Sedgley was remanded in custody for sentencing on June 30 so a mental health report can be prepared.
