Three More Men Charged Over Billion-Dollar Drug Bust

Three more men have been arrested and charged over a massive $1 billion drug haul that was found on a tiny island off Western Australia after a yacht ran aground.

Police swooped on Burton Island off Geraldton last week, finding French national Antoine Dicenta, 51, and British man Graham Palmer, 34, allegedly with 1.087 tonne of methylamphetamine, cocaine and ecstasy.

On Thursday, WA Police said a 45-year-old American man, a 35-year-old British man and a man from NSW, 50, had been charged with conspiring and attempting to possess the drugs with intent to sell or supply.

The Australian was arrested at Perth Airport while the other two were nabbed in the CBD on Wednesday.

Police Commissioner Chris Dawson said it would be alleged they were "the shore party".

"They were in another boat and they were ready to receive," Dawson told ABC radio.

"We've disrupted an international big drug syndicate here."
