The 20-year-old man had been out drinking all night before the incident occurred about 5am on April 11 this year.

The man returned home and began knocking on the door yelling at his partner to let him in, before walking around the home attempting to gain entry.

The woman yelled out to him from inside their home telling him he wasn't welcome and their relationship was over after she had received a video of him dancing with other women while he was at the pub, court documents revealed.

The pair began arguing before the man explained he didn't know what she was talking about as his phone was flat.

The woman held her phone up to the window to show him the video explaining he had done wrong by her, when he got aggressive.

"If you want to start on that I'll jump on your head," he told the woman.

He then went to the front door of the home and barged through it, damaging the locking mechanism before he approached the woman and with an open hand began to hit her over the head.

According to police the woman defended herself from further blows by pushing him away from her, and asked him why he was doing this.

The man told her "you turned me into this", when the woman asked him to be quiet as her young daughter was asleep in a room close by.

The woman went into the room with her daughter while the man kept pacing around the house shouting abuse, still stating he was going to jump on the woman's head.

The woman contacted her family and friends who loved across the road to contact police, and she took her young daughter across the road to wait.

Police arrived when the man was arrested and taken to Dubbo Police Station.

In Dubbo Local Court on Wednesday, the man pleaded guilty to one count of domestic violence related common assault, one count of stalk and intimidate intending fear or physical harm, and one count of destroy or damage property.

Defence lawyer Carmen Just said he was a young man, had no criminal history, and no issues in relation to alcohol or mental health.

Ms Just said her client had been gainfully employed at Fletcher International Exports for the last nine months, and was also heavily involved within the rugby league community in Dubbo.

Magistrate Theresa Hamilton said despite his early plea of guilt and young age, his behaviour on this night was "obviously totally out of line".

"You need to stay out of trouble and control your temper if it's going to lead to this behaviour," she said.

The man was convicted and sentenced to a 12-month community corrections order.
