Three Canadians are accused of trying to smuggle 95kg of cocaine into Sydney on a cruise ship.
The 63-year-old man and two women, age 23 and 28, were arrested on Sunday after police and sniffer dogs searched the vessel when it berthed in Sydney and found cocaine in suitcases.
The Australian Federal Police say the trio will face Sydney Local Court on Monday charged with importing a commercial quantity of cocaine.
They face a maximum penalty of life imprisonment.
The joint operation by the AFP and Australian Border Force received co-operation from the US Department of Homeland Security Investigations, New Zealand Customs Service and the Canada Border Services Agency.
