Love Machine nightclub staffer Joseph Hosri was forced to give evidence in Melbourne Magistrates Court on Monday about the April shooting of security guard Aaron Osmani and patron Richard Arow.

Mr Hosri worked as a door selector at the club, telling the court his role was to enforce the dress code and attract a "certain crowd".

"We avoid letting in big tattooed scary people," he said.

Mr Hosri was quizzed about a young woman being ejected and banned for six months only three or four weeks before the shooting.

The woman was the daughter of Nabil Maghnie, an underworld figure with criminal connections. His 18-year-old son Jacob Elliott is charged with murder over the shooting.

Mr Hosri said he had no recollection of the woman. He said he didn't know Mr Maghnie but knew of him.

He also couldn't recall a man described as skinny, with "braces and pimples" being ejected from the club on the night of the shooting, or of security personnel speaking to people in a black Mercedes.

"All I recall is seeing a friend die in my hands ... I have no recollection other than him in my hands," Mr Hosri said.

Prosecutor Kevin Doyle had asked for the hearing to be held behind closed doors, suggesting Mr Hosri's safety was at risk.

But Mr Hosri objected.

"I'm not doing closed court," he said. "I have no concerns."

His lawyer William Barker said Mr Hosri was more concerned his safety would be jeopardised if his evidence was heard in secret.
