SYDNEY (AFP) - Four Taiwanese men have been arrested and charged over the seizure of crystal methylamphetamine worth A$130 million (S$151.6 million) in Australia, the police said on Wednesday.

Australian Federal Police said four suitcases holding more than 135kg of the drug known as "ice" were seized at an inner city apartment in Melbourne on Tuesday.

"The estimated street value of the seizure is approximately A$130 million," the police said in a statement with the Australian Crime Commission.

The four men, who are aged 20, 23, 24 and 29, have been charged with a range of drug-related offences, some of which have a maximum penalty of life imprisonment.

The police said they were still looking into whether the drugs were imported.

"Traditionally with this quantity of ice, you would expect it to come by land or sea," Australian Federal Police commander Bruce Giles said.

The authorities said the group was tracked by an Australian Crime Commission task force which detects illicit money flows.

In a separate case earlier this month, six Taiwanese men were charged with importing 50kg of crystal meth into Australia.
