Mr Deng has been charged with five offences, including murder, drug-related offences, firearm-related offences, and participating in a criminal group.
He was denied bail and is set to appear before Parramatta Local Court.
Detective Acting Superintendent Virginia Gorman said that police believe Dut Deng was the sole shooter in the assassination plot.
The investigation, led by Task Force Magnus, targeted gun-related and violent crimes, specifically focusing on the murder of Alen Moradian.
“All investigations lead somewhere and this one has led to somewhere who remained in the country, which was fortunate for us,” she said.
The investigation continues, with law enforcement committed to dismantling organised crime networks involved in violent activities.
