Authorities tracking money linked to offshore crime syndicates have seized $130 million worth of ice packed into plastic bags and stacked in four bulging suitcases in a Melbourne apartment.
Four Taiwanese nationals in Australia on tourist visas have been charged over the crystal methylamphetamine haul.
More than 135kg of the drug was seized, an amount which police say would have been on-sold to users 1.3 million times over.
A joint Australian Federal Police and Australian Crime Commission (ACC) operation netted the illicit product, after intelligence was provided through the Eligo national task force which tracks money laundering.
ACC national manager of investigations Richard Grant said people were increasingly being targeted by cartels and offshore syndicates, focused purely on profit.
"One of the things for the Eligo task force is going after the profits and this is how we were able to track these particular syndicate members to end up with these seizures," he told reporters on Wednesday.
AFP commander Bruce Giles said the bust was significant and investigations into the exact source of the drugs were ongoing.
"Traditionally with this quantity of ice, you would expect it to come by land or sea," he said.
The drugs were found in four suitcases in an inner-city Melbourne apartment on Tuesday afternoon.
Four men have been charged with a range of drug offences.
A brief hearing in the Melbourne Magistrates Court on Wednesday was told the men were in Australia on tourist visas and have no fixed address within the country.
Shu Yi Lin, 20, and Li Ping Chen, 23, were both charged with possessing a commercial quantity of ice suspected of being illegally imported.
Chun Lan, 28, and Ming Hsuan Ou, 23, were each charged with trafficking a commercial quantity of ice.
They were remanded in custody to appear again in November.
