Daniel Taylor has repeatedly denied any involvement with a tobacco smuggling ring in his defamation trial against a news organisation in the Federal Court.
The son of Kings Cross identity John Ibrahim is suing Nationwide News over a 24-page spread on his family which he says made him out to be a mobster or Mafia member.
The Sunday Telegraph is standing by their spread published on June 23, 2019, and has put forward a "justification" defence.
The article referred to Michael Ibrahim's involvement in a drug and tobacco smuggling ring and to Mr Taylor being acquitted of a charge of illegally handling $2.25 million in cash linked to the operation.
His description as the "wise guy" son of John Ibrahim in the article "Inside the house of Ibrahim Unauthorised" could mean smart alec or, that he was involved in organised crime, his barrister Kieran Smark SC earlier said.
In his second day in the witness box, Mr Taylor on Tuesday denied any knowledge of $750,000 found in his apartment following a search warrant by police.
"I was not present when money was counted in my unit and I have no knowledge of money being counted in my unit," his affidavit reads.
The Telegraph's lawyer Dauid Sibtain also questioned Mr Taylor, also known as Daniel Ibrahim, on recorded telephone interceptions where key players allegedly involved in the black market tobacco operation were involved.
In a conversation with his uncle Michael Ibrahim, Mr Taylor said he sounded "very high" on cannabis and pain killers and could not remember what they were speaking about.
His text message saying "I don't give a f*** what happens," related to the cut in profit following the illegal operation, Mr Sibtain suggested.
"No, I don't agree," Mr Taylor said.
Another secretly recorded communication between Mr Taylor and an alleged tobacco smuggler shows the pair planning to meet up at a Rose Bay cafe in Sydney, but Taylor denies they did.
"I had other things to do," he said.
"Wouldn't you say, if you had other things to do, you would say so?" Mr Sibtain said.
"I don't recall," Taylor said.
While he had a strained relationship with his father, he was close to his uncle Michael who gave him the $17,000 bond to set up a cafe, he earlier told the court.
But the cafe worker became depressed and saddened after the publication of the newspaper article, struggling to believe it could print such an article without getting any comment from him or his solicitor.
"I had a fear of going out in public to avoid being recognised by people," Mr Taylor said on Monday.
Mr Taylor will continue to give evidence before Justice Anna Katzmann on Wednesday.
