The younger brother of Olympic kayaker Nathan Baggaley is accused of being one of two men who dumped about $210 million worth of cocaine during a sea chase off the northern NSW coast.
Dru Anthony Baggaley, 36, and Anthony Trevor Draper, 53, face potential life sentences if convicted after being arrested following the chase 70 kilometres off Byron Bay on Wednesday.
It's alleged the pair threw 600 kilograms of cocaine overboard whilst being pursued by a naval vehicle and Queensland police assets.
After a short pursuit the pair were arrested and both faced Southport Magistrates Court on the Gold Coast on Wednesday charged with possessing a commercial quantity of drugs and drug importation.
Lieutenant Commander Ken Brown, who was skippering the ADV Cape Fourcroy during the chase, said his crew had retrieved 30 bags of cocaine from the sea.
"I was directed to recover the items before resuming pursuit of the particular craft," Lt Cmdr Brown said.
"My crew retrieved the items from the sea which were identified as containing 600 kilograms of cocaine."
Police believe more arrests may follow as their investigations continue.
Australian Federal Police detective superintendent Andrew Donoghoe said the haul was a significant one.
"These two men are facing the prospect of life in prison," Det Supt Donoghoe said.
"Importantly our joint efforts have stopped more than 600kg of cocaine from ever reacing Australian shores. That represents approximately three million street hits that will never take place."
Baggaley and Draper have both been remanded in custody and will reappear in the same court on August 20.
