An ice user who disarmed a Vietnamese businessman in a Sydney meth lab and then used the machete to kill him showed remorse by telling police where the body was buried, a judge has been told.
Zulfukar Aljubouri has pleaded guilty to the May 2014 manslaughter of 50-year-old Minh Phuoc "Paul" Nguyen at a Bankstown unit used by the victim as a "safe house" for the manufacture and supply of methylamphetamine.
The 26-year-old, who was originally charged with murder, also pleaded guilty to unlawfully disposing of a corpse.
Aljubouri in 2018 led police to bushland south of Sydney where they located the remains of Mr Nguyen who vanished after driving off from a CBD hotel in a gold hire car in May 2014.
Aljubouri faced a sentence hearing in the NSW Supreme Court on Thursday, along with Rafat M Shaker, 28, and a 22-year-old man who can't be named as he was a juvenile at the time.
Shaker pleaded guilty to concealing a serious indictable offence of another person while the other man admitted being an accessory after the fact to manslaughter.
Aljubouri's barrister, Carolyn Davenport SC, argued her client showed contrition by taking police to where the body was concealed so he could have a proper burial.
"Mr Aljubouri was not armed and it was certainly a spontaneous offence initiated by the deceased by producing a machete," she said.
"Mr Aljubouri acted in the way he did because he believed his life was at risk from Mr Nguyen through the use of that machete."
Aljubouri, an ice user and seller, and Mr Nguyen, who was involved in the production of the drug, met in late 2013.
"From that time until the time of his death, Mr Nguyen supplied the offender with methylamphetamine and the offender, in turn, acted as a courier to various customers of Mr Nguyen," the agreed statement of facts said.
On the evening of May 1, 2014, Mr Nguyen became angry at Aljubouri for bringing two men to the Bankstown unit.
"He claimed he had jeopardised the operation by showing them the location of the 'safe house'.
"He was also angry that Mr Aljubouri had not picked up a package as directed by him."
They argued for a long time as Mr Nguyen continued to accuse him of compromising his drug business by revealing the location of the house.
When Aljubouri tried to leave, Mr Nguyen produced a machete and came towards him, before the Aljubouri managed to disarm him and stab him in the ribs.
In the early hours of May 4, four people in the unit block saw a number of men dragging or carrying a sleeping bag, with one witness saying it looked like it contained a human body.
Justice Helen Wilson will sentence the three men on March 1.
