Police seized 3.86 kilograms of methylamphetamine (ice) and 700 grams of cocaine, with a conservative street value of over $4 million, as well as $1.57 million in cash.

Six people have been charged with trafficking in a controlled substance and dealing in the proceeds of crime, with the matters now before the court in Tasmania.

Investigations included the execution of a series of searches of vehicles and premises by police in Queensland and Tasmania, resulting in the seizures and arrests.

The results came as the result of Operation Carnegie, led by Tasmania Police's Crime and Intelligence Command launched last year to further enhance the coordination of specialist resources to investigate crime at all levels - and was supported by relationships with the Australian Federal Police, Australian Criminal Intelligence Commission and Queensland Police.

Tasmania Police Assistant Commissioner Jonathan Higgins said the outcomes of the investigation demonstrated the dedication of working relationships to target the threat of organised crime syndicates.

"[Those] involved in the manufacture and distribution of drugs in Tasmania should take notice. We will identify you, we will investigate you and we will prosecute you for the importation and distribution of illicit drugs into Tasmania," he said.

"Illicit drugs have a damaging and broad impact on our community, particularly in relation to health, law and order. Police and other law enforcement agencies work tirelessly to target the supply of illicit drugs to our community and this latest operation is an example of this coordinated effort."

AFP Assistant Commissioner Bruce Giles said this was another example of the strength of the AFP's partnerships with state and territory police and other partners across Australia to protect the Australian community.

"Working together we have been able to achieve a historic moment and prevent further harm to the Tasmanian community," AFP Assistant Commissioner Giles said.

"We will continue to target those who exploit cross border transport whether that is by air or sea to prevent harm to all Australians by those who seek to profit from the misery they inflict on vulnerable Australians."

Assistant Commissioner Katherine Innes from the Queensland Police Crime and Intelligence Command said the success of this operation comes down to the highly skilled law enforcement officers and detectives sharing information and strategies capable of working across state boundaries.

"I'd like to acknowledge the hard work, professionalism and dedication displayed by every officer involved in Operation Carnegie. Your commitment to dismantling these drug syndicates makes a difference and makes the community safer.

"We will continue sharing our expertise and working collaboratively with our national and interstate counterparts to ensure the successful disruption of these criminal networks."
