Detective Sergeant Mark James, of the Hamilton police crime investigation unit, said an alleged home invasion and assault occurred in Hamilton's Coleraine Road early Wednesday.

Police allege Samantha Lanyon, 28, enlisted Warragul's Rhys Swarbrick, 29, to break into the victim's house and assault him.

Ms Lanyon and the man were known to each other.

She appeared in Warrnambool Magistrates Court on Wednesday.

During a bail application, Detective Sergeant James said he had viewed a Court Integrated Services Program report which he believed showed the woman was "approaching rock bottom".

"Perhaps she has got a big fright and realises she has to get her alcohol and drug issues under control," he said.

The detective alleged the Warragul man had slashed a car tyre before entering the Colerain Road property, punching the male victim, a well as a wall, and then fleeing.

He said shortly before the alleged aggravated burglary, the man and woman were seen walking towards the address by a patrolling police unit.

The court heard Mr Swarbrick was armed with a knife when he entered the Coleraine property.

Detective Sergeant James said there was no suggestion that Ms Lanyon was involved "in the actual physical offending".

"It's going to be alleged that she was nearby," he said.

"It's a circumstantial case against her at this stage given the fact that he would have had no idea where the victim's address was and in fact became lost in Hamilton after (the alleged offending),"

"He ended up basically handing himself into police because he had no idea where he was."

Police allege Mr Swarbrick busted into the victim's house about 1.30am Wednesday.

The pair have each been charged with causing criminal damage, aggravated burglary and assault.

The woman has also been charged with contravening a court order.

Solicitor Julia Ray said the police case was weak and there were "very serious triallable issues".

She said that if the matter went to trial, Ms Lanyon could spend more than two years on remand waiting for her day in court.

Ms Lanyon was released on bail with strict conditions, including she not attend any licensed premises and take part in the Court integrated Services Program.

Mr Swarbrick appeared in Hamilton Magistrates Court on Wednesday afternoon, did not apply for bail and was remanded in custody.

The pair will appear in court again on November 5 for a committal mention hearing.
