Investigators are piecing together how more than $120 million of cocaine got into WA and where it was going.

Australian Federal Police Commissioner Reece Kershaw (above) told Gareth Parker on 6PR Breakfast a joint operation between the AFP, WA Police, intelligence authorities and Australian Border Force seized the haul in a campervan in Port Hedland, after investigating an alleged organised crime syndicate, which may have sailed the drugs to WA aboard an international bulk shipping carrier.

“So far we know there’s a German national involved, and also a man from NSW,” he told Breakfast.

“No doubt this will be an organised crime syndicate based in Australia that put in the order.

“To get that amount of narcotics it’d normally have to come from a big ship or something of a big size.”

The 320kg stash — split into 1kg plastic-wrapped blocks — was seized by authorities on Sunday, with a 49-year-old from NSW and 37-year-old from Germany now in custody.

It will alleged the two men used a 6.5 metre boat to sail out nearly 30km offshore to pick up the drugs — possibly from a bulk carrier.
