The girlfriend of former Kings Cross nightclub owner John Ibrahim has testified he told her he knew how a pistol came to be in her apartment, but refused to tell her more.
"He told me it was best I didn't know and that I was in enough trouble as it is," Sarah Budge told the NSW District Court jury hearing her gun possession trial.
The model and restaurateur became tearful when asked why she was still in a relationship with 51-year-old Mr Ibrahim, saying: "Because I don't think he deliberately put me in a bad position.
"I just don't think that he would try to do something to hurt me."
The 29-year-old has pleaded not guilty to three weapons possession charges, telling the jury she had no idea a stolen, defaced Glock 26 pistol and loaded magazine were hidden in a teapot box in her bedroom wardrobe.
The weapon was found by federal police in August 2017, when they raided a series of properties including Budge's Double Bay unit and Mr Ibrahim's Dover Heights clifftop home.
Giving evidence on Tuesday, Budge said she was very upset after being arrested and spending the night in the cells before being released on bail.
She said she confronted Mr Ibrahim, asking if he put the gun in her home because she wanted to know what was going on.
"I knew I had nothing to do with it getting there," she said.
But while her boyfriend told her he knew how the gun got there, he refused to give her any more information, saying it was best if she didn't know - a stance they argued about over the years.
Her barrister, Simon Buchen SC, previously suggested Mr Ibrahim or an associate hid the pistol and ammunition in the wardrobe the day or days before police found them.
"I don't think he did. I don't know," Budge told prosecutor Christopher Taylor.
"I suggest that the position of him knowing but not telling you involves a significant breach of trust in your relationship?" Mr Taylor said.
"Yes, it was hard to deal with, absolutely," she replied.
The prosecutor suggested there was a "heightened sense of security" about July 2017 when Mr Ibrahim's memoir, Last King of the Cross, was released.
His family home and two brothers had previously had been shot at, contracts were said to be taken out on his life, a brother had "destroyed" two bikie gangs and Mr Ibrahim had named people in his book who were allegedly involved in crimes, Mr Taylor said.
"I don't think he was worried people were going to do something," Budge said, telling the jury he had referred to events from a long time ago.
"I never got the vibe he was worrying about safety."
She denied a suggestion she had the firearm at her place to enable her to protect herself if the need arose.
"I have never felt nervous about my safety."
The trial continues before Judge David Arnott.
