Jarad Macfarlane, 23, had been drinking at the Macquarie Inn with his father when he consumed seven Toohey's New beers before the violent attack occurred on June 9.

About 1.54pm the pair returned to a home through the backyard, and began discussing issues they had with each other.

According to police, neither agreed what the other had to say, causing them both to become angry and agitated toward one another.

Macfarlane punched his father three times to his head, causing a cut, bruising and pain to his left eyebrow, before punching him another three times to the other side of his head.

Macfarlane's father pushed him, to diffused the physical behaviour, but was punched by his son another four times to his face, causing significant swelling to his nose.

Both fell to the ground, when Macfarlane's mother saw the incident from inside the house and approached them, placing herself in the middle of them in an attempt to stop the two from fighting.

However as a result she fell to the ground and hit her face on the concrete.

The fight stopped a short time later, when Macfarlane's father ran inside and locked the door.

Macfarlane yelled "I want my washing", before picking up a brick and throwing it through the glass sliding door.

He walked around to the front of the house and picked up another brick from the broken mailbox, when his mother went outside in an attempt to calm him down.

However, Macfarlane spotted his father behind the front door, and began hitting it with the brick threatening "I'm gonna kill you".

Macfarlane briskly walked away from the house when police arrived. Officers said Macfarlane appeared to be severely intoxicated as his eyes were bloodshot, his speech was slurred and was not walking straight.

His father walked out of the house and police immediately saw swelling and bruising to his face, and his shirt had been torn.

According to police, Ambulance officers arrived and stated Macfarlane's father's nose may be broken.

In Dubbo Local Court, Macfarlane pleaded guilty to one count of stalk or intimidate indenting fear or physical harm, one count of destroy or damage property and one count of assault occasioning actual bodily harm.

Defence lawyer Molly Bland said Macfarlane had engaged with his GP and developed a mental health plan for depression and anxiety.

"He tells me he can't remember anything, but has apologised to his father, and has already sent money to replace the front door," she said.

"He tells me he hasn't had anything to drink in terms of alcohol since the incident, and plans to continue to engage with his GP and also a mental health councillor."

Magistrate Theresa Hamilton accepted Macfarlane was "heavily intoxicated" at the time of the incident, however said it was still "not an excuse".

Taking into his young age, no previous criminal history and the steps he had taken toward his mental health, Magistrate Hamilton convicted and sentenced Macfarlane to a 15-month community corrections order.
