IT WAS a case of barbecue banter gone mad, steaks, a pet chicken and a machete-wielding flatmate.
The unusual combination at a seemingly normal barbecue at John Graham Potts and his flatmate's home on May 19 last year ended in deep gash and 12-month jail stint.
As Crown prosecutor Isaac Munsie explained in Brisbane District Court, where Gladstone-born Potts was sentenced for grievous bodily harm, the gathering went haywire when Potts and his roomie argued over steaks and pets.
"The complainant became angry because the defendant hurt a chicken in the house," Mr Munsie said on Monday.
Not one to chicken out, the fired-up flatmate pushed Potts, 46, over the couch.
Court documents stated the flatmate tended to his pet and relocated the egg-laying creature outside the Brisbane house.
In the meantime, an intoxicated Potts grabbed a machete from the bedroom and made a beeline for his roomie.
The flatmate grabbed a shovel from outside to protect himself.
Mr Munsie said Potts hit his flatmate on the thigh but did not break the skin.
Potts had another go, this time swinging the machete above his head and bringing it down on the victim's forearm.
Party-goers then tackled Potts to the ground and took away the machete.
Judge Anthony Rafter said the victim had suffered a five centimetre laceration and cut tendons.
The defence argued the accused's action were at a time when he had no employment and no control over his alcohol problem.
The court heard Potts now lived on North Stradbroke Island, was undergoing rehabilitation and had a peaceful life.
Judge Rafter pointed out Potts had a history of violent assaults, including on police and a hospital security guard.
He sentenced Potts to three years jail to be released on parole after one year.
