“It will be alleged in court that the three men were responsible for purchasing a boat and collecting the cocaine after a bulk carrier vessel dropped it into the ocean off the coast of Western Australia,” the Australian Federal Police (AFP) said.

A boat, two vehicles and $30,000 in cash were also seized from the WA property, police said. 

Queensland properties linked to the men in Toogoolawah, Taigum and Redcliffe were also searched by police.

Police launched an investigation after a tip-off about a suspicious vessel, with a bulk carrier travelling from Fremantle searched when it landed in Port Lincoln, South Australia, on Wednesday.

The joint operation involved the AFP, Australian Border Force (ABF), Western Australia Police Force, and Department of Home Affairs.
