Two men have been charged after more than 20 kilograms of cocaine was seized during a joint-agency investigation into international drug trafficking by NSW Police and the Australian Border Force.

A joint investigation into the importation and supply of cocaine was established by police detectives from the drug squad and investigators from the ABF in September, called Strike Force Brundson.

As part of their joint inquiries, ABF officers inspected a large consignment from Spain on Monday, October 9, where they located and seized 21 kilograms of cocaine concealed in tiles.

The cocaine has an estimated street value of $6.3 million.
