In the vision, Ms Berry is covered in OC foam, or capsicum spray, with her underpants down and bare legs, when two officers enter the room.
The first officer, Leading Senior Constable Nicole Munro, is seen nudging the prisoner in the lower torso with her foot, before Senior Constable Repac stood repeatedly on her bare ankles and kicked her in the shin.
Judge Lacava said it was clear the officer had kicked her “with force” when she was “completely subdued … on the floor drunk, on her stomach, with handcuffs behind her back” and her “buttocks exposed”.
He said Ms Berry was “completely humiliated and vulnerable”.
But Judge Lacava also conceded that the officer had an otherwise unblemished record and was young, being just 25 years old at the time of the incident.
He said it was appropriate to adjourn the sentence and place Senior Constable Repac on a 12 month good behaviour bond, which means he will not have a conviction recorded against his name for the assault.
Senior Constable Repac’s actions were a “spontaneous” mistake, said the judge, that amounted to one or two seconds of conduct.
Young people occasionally “do silly things”, he said.
But she did not blame the Senior Constable himself for her treatment, and said there was a lack of leadership at the station.
Judge Lacava said he took those remarks, which he regarded as “gracious”, into account in choosing an appropriate sentence.
He also said Senior Constable Repac had already been suspended without pay from the police force and would face problems finding a job with a recorded conviction against his name.
His family and colleagues were in court for the sentencing and became visibly emotional when the officer was told to leave the dock after he was asked if he agreed to the 12-month good behaviour bond.
The Senior Constable was originally charged with a total of six counts of common assault in 2017, but after an eight-day trial last year the jury was unable to reach a verdict on the remaining five charges along with a single assault charge for his co-accused, Leading Senior Constable Munro.
