Shamiran Benjamin's boyfriend ended their date at the Star casino in 2012 by firing a gun into his neighbour's house during a drunken argument.
Hours later, Ms Benjamin found herself on the side of the M5, under arrest with her then boyfriend, Ali Khaled, for concealing a serious indictable offence.
The Sydney District Court heard on Thursday that the couple had been arguing outside his Wiley Park home about 3am on January 29, 2012.
Ms Benjamin, who had been sitting in her Nissan Pulsar parked on Denman Avenue, had been upset about Khaled's drunken behaviour at the casino.
"Don't disrespect me, bitch", he told her, before banging his fist on her car.
When she replied, "no, please stop", a neighbour, fearing for Ms Benjamin's welfare, called out but Khaled abused the man, before going into his unit and returning with a 9mm glock pistol. He then fired a shot at his neighbour's building.
Ms Benjamin drove off but soon returned and picked up Khaled. She told the court he had threatened to go to her parents' house if she had not come and got him.
Police then pulled over the Pulsar on the M5 and questioned Ms Benjamin. She did not mention Khaled's involvement in the shooting.
The pistol was discovered wrapped in a jumper in the car and the pair were arrested.
Khaled pleaded guilty over the shooting last year and was sentenced to four years in jail, with a non-parole period of two years and six months.
But in sentencing Ms Benjamin, Judge Ray McLoughlin accepted she had been in shock and frightened of Khaled, who had been sitting next to her in the car when police had questioned her.
She escaped conviction over the incident and was put on a two-year good behaviour bond after earlier pleading guilty.
Ms Benjamin maintained in court that she had not known that Khaled had bought the gun with him into her car.
The court heard Ms Benjamin was suffering from anxiety and depression stemming from "physical and emotional abuse" she had experienced as a child at the hands of her father and in a previous abusive relationship.
Judge McLoughlin accepted her career in childcare had been put on hold because of the charge and that her parents had disowned her for four months. He said her chance of reoffending was low.
"I'm so happy," Ms Benjamin said to her supporters as she left the court.
