Schink and the victim began to yell at each other while friends in the vicinity told the victim to "just go" and "leave it".

The shift manager of the Hotel escorted Schink from the venue, however he waited outside highly agitated, taking off his shirt in preparation for a fight with the victim.

As the victim left the Milestone, Schink was spotted standing near the garbage bins. According to court documents Schink ran towards the victim and punched him on the left side of his face, causing immediate pain and blood to fill his mouth.

After the manager spoke to all parties and told them to leave, a further dispute took place on the footpath.

According to court documents Schink and the victim knew each other through the Dubbo car scene.

The victim went on with work duties the next day, taking nurofen despite suffering from intense jaw pain. Later that day he was told to go to Dubbo Hospital where tests revealed Schink had fractured his jaw.

Five plates and 20 screws were required to mend the damage to the victim's jaw at Westmead Hospital, Sydney.

At Dubbo Local Court Schink pleaded guilty to one count of reckless grievous bodily harm and one count of common assault.

Defence lawyer Jai Silkman said Schink had "accepted he was highly intoxicated on the night", but had a limited criminal history and had voluntary completed a rehabilitation program for people with substance abuse issues.

The court heard Schink had also enrolled in another two programs for mental health support and another aimed at changing the behaviour of men.

Magistrate Sharon Freund warned Schink should consider his behaviour if he wanted to be a positive role model for his family.

"I take comfort in the fact that you seem to have hit rock bottom ... you've taken what's happened and sought help," she said.

"You should be proud of yourself for doing that."

Magistrate Freund sentenced Shink to a 12-month jail term, however ordered it to be served in the community in the form of an intensive corrections order.

Schink was banned from drinking alcohol for 12 months, as a condition of the intensive corrections order sentence he was handed for the reckless bodily harm charge.

For the common assault, Schink was placed on a community corrections order for two years.
