A single phone call to police from an anonymous source sparked a year long investigation that netted Australia’s largest recorded ice seizure - 585 kilograms worth an estimated $438 million.

NSW Police Commissioner Andrew Scipione told a press conference on Thursday the Joint Organised Crime Group, consisting of leading law enforcement agencies, would not have arrested the Asian drug syndicate’s three men without that simple tip off.

"That one phone call was the one thread that allowed us to pull and unravel a syndicate that will be stopped forever.

"A member of the public had seen that things weren’t right at a particular location at a commercial premises and contacted the police," he said.
