Stabbing victim told mother 'I'm going to die'

The victim of an alleged stabbing murder in Sydney's west told his mother he was "going to die" before collapsing covered in blood, a court has heard.

Bilal Rahim, Joseph Nehme, Viliami Taufahema, Sherene Rizk and Lisa Anne Price are facing a NSW Supreme Court jury trial over death of Luke Lembryk in the early hours of December 7, 2019 at the unit he shared with his mother in Condell Park.

Rahim, Nehme , Taufahema and Price have pleaded not guilty to charges of murder, the court heard on Tuesday, while Rizk is fighting a charge of being an accessory before the fact.

Crown prosecutor Chris Taylor, in his opening address, said there would be evidence that Mr Lembryk's mother - after investigating a "thumping noise" in the night - was bashed inside the dark unit, before spotting her son in the light of the television.

The trial was expected to hear, the barrister said, that Mr Lembryk's mother screamed after she saw him bent forward, holding his stomach, and covered in blood, when he said: "I'm going to die mum, I'm going to die".

Mr Lembryk was pronounced dead at the scene around 2.45am the same morning having suffered stab wounds to his heart, arm, leg and finger, Mr Taylor told the court.

He said Rahim, Nehme and Taufahema went to the unit to do the "Condell Park job", with "specific guidance" to find the residence given via telephone by Price, who had previously been there and seen wads of cash, after initially connecting with Mr Lembryk via Tinder.

Evidence would also show, the barrister said, that Rizk had admitted in an interview with police to taping a knife to Nehme's body hours before the alleged murder took place, with the weapon described in court as "like a sword".

In the hours before the stabbing, at Rizk's home in Rockdale, "logistics" of the job were figured out via phone calls, before Nehme went to Condell Park on a motorbike, while Rahim went to pick up Taufahema from a home in Pennant Hills, the court heard.

The trio later met near the victim's residence, with Nehme arriving on his Harley Davidson motorbike and Rahim and Taufahema in a white ute.

Nehme was in need of money, the court heard, and had described himself as "broke" the day before the alleged robbery gone wrong, while Price had previously said to a friend: "We should do this guy over".

The trial continues on Wednesday before Justice Richard Button.
