The 32-year-old man, who cannot be named because that would identify the victim, pleaded guilty in Warrnambool Magistrates Court on Monday to assault-related offences and breaching a family violence intervention order.

The court heard he called and messaged the victim numerous times despite a court order prohibiting from contacting her.

Then on Friday, he attended the victim's address and the pair began arguing.

The man became verbally abusive and pushed the woman before aggressively grabbing her by the face, the court heard.

The victim begged the man to leave.

He left the address and was later picked up by police before being conveyed to Warrnambool police station and lodged in the cells.

Legal Aid lawyer Belinda Northey said the man had numerous health conditions and a criminal history that included periods of time in custody and an ongoing corrections order.

The man was jailed for 45 days with three days already served in custody on remand.

Magistrate John Lesser said it was important for the man to serve his time and then continue to engage with corrections.

"It's important you take steps to not end up back in custody," he said.
