Australian police have seized a massive haul of liquid methamphetamine, known as "ice", worth about £620 million, that was hidden inside gel bra inserts and glue bottles.
Four Chinese nationals, three of them from Hong Kong, have been charged over their alleged role in the importation and manufacture of 720 litres of the drug.
"This is the largest seizure of liquid methamphetamine in Australia's history and one of the largest drug seizures in our country's history," Justice Minister Michael Keenan told reporters in Sydney.
The seizure was the result of a joint investigation by Australian authorities and the Chinese National Narcotics Control Commission, Mr Keenan said.
The drugs haul was biggest in Australia since 2014, when police seized around $1.5 billion in ecstasy and methamphetamines imported from Europe.
The Australian government declared a crystal methamphetamine "epidemic" last year and launched a national taskforce to tackle the drug.
Around 2.1 percent of Australians used methamphetamines or amphetamine drugs in 2014, according to the Australian Institute of Health and Welfare, among the highest rates of illicit drug use in the world.
