Two men charged after 91kg of meth found inside industrial coffee grinder

Two Sydney men have been charged after 91.4 kilograms of meth valued at an estimated $80 million was allegedly found hidden inside an industrial coffee grinder in Brisbane.

Australian Federal Police began investigations early this year after the drugs were detected at Brisbane International Airport on a commercial flight.

The aircraft had started its journey in Guatemala before heading to Mexico and Hong Kong ahead of its arrival in Australia.

Officers swapped out the drugs in the coffee grinder with a harmless substance and reassemble it for collection.

"AFP officers tracked the consignment as it was transported from Brisbane to a home in the Sydney suburb of Cabramatta," police said.

The home was searched on January 31, where two men, aged 20 and 24, were arrested.

One had allegedly tried to escape over a fence during the arrest but was stopped.

"Investigators seized a mobile phone, a USB, 500g of a substance believed to be amphetamine, tools allegedly used to access the coffee grinder and $40,000 suspected to be the proceeds of crime from the home," police said.

The pair were charged with attempting to possess a commercial quantity of a border controlled drug which carries a maximum sentence of life imprisonment.

They did not apply for bail when they fronted Downing Centre Court on Thursday last week and the matter has now been adjourned to late March.

Police said they are continuing investigations and more arrests are possible.

Commander John Tanti said the find was a blow against transnational organised crime.

"Had the import been successful it would have made the members of the syndicate rich but it would have caused havoc on the streets of Australia," he said.

"Criminal syndicates go to great lengths to conceal their activities but it is impossible to hide from the AFP and our domestic and international partners."
