Michael Patrick Malady, 41, of Hoki Street, Warrnambool, pleaded guilty in the Warrnambool Magistrates Court to causing criminal damage and unlawful assault. 

He was placed on a 12-month community corrections order which involves assessment, treatment and rehabilitation for alcohol, drugs and mental health issues.

Police said Malady and his partner had been together for three years and on the morning of September 18 were drinking with her mother and daughter.

At 11.40am they argued and Malady demanded his partner leave the home. He threw her clothes out a window, called her names and kicked and smashed a window of her car.

The woman left to seek alternate accommodation but returned to check on the welfare of her mother and daughter.

The daughter armed herself with a stick when she heard Malady make a threat to kill her mother, but he took the stick from her and punched her to the face.

Police were called and arrested Malady, who admitted breaking the window but said he only punched the daughter because she was assaulting him with the stick.

During a previous hearing a magistrate said Malady was a huge man, was clearly enraged, there was alcohol involved and any self-defence response was excessive. 

Solicitor Kiernan Celestina said his client admitted pushing the victim with an open hand to the face. He said Malady had a bad reaction to events on the day and admitted his actions were inappropriate.

Magistrate Peter Mellas said photos of the victim showed bleeding and injuries to her face and it looked like a significant assault. He said it appeared that Malady blew up every couple of years and the recent offending was part of a long-term pattern.
