Former Eels player Aukuso Junior Paulo, 34, has been charged with supplying 900 kilograms of cocaine worth an estimated $180 million.
Kigi Kamuta, 39, has been charged with the same offence even though police are yet to seize the drugs.
Fellow former Parramatta player Royce Royal Hura, 27, and Paulo were caught in two cars last Wednesday allegedly with guns and $650,000 cash in Sydney’s Centennial Park.
They have remained in custody since last week following a court appearance when they were charged with unlawfully possessing weapons, dealing with the proceeds of crime and participating in a criminal group.
Paulo and Kamuta on Tuesday copped an extra charge of supplying a commercial quantity of a prohibited drug.

"There are 900 kilograms of cocaine that will not reach the streets of Sydney due to the good work of those staff from the organised crime squad and our partner agency," Detective Chief Superintendent Tony Cook told reporters in Sydney.
However, Cook was unable to confirm the whereabouts of the drugs.
"Our investigations are ongoing and I can't speak about the operational detail," he said.
Paulo is due to appear in Sydney's Central Local Court on the fresh charges on Tuesday.
Paulo played for the Eels (2007-2009) before stints with the Dragons (2010) and Penrith (2011) while Hura played for Parramatta in 2010.
