Five Australia-bound Tamil asylum seekers vanished in shark-infested waters near the Cocos Islands over May 5-9. They were seeking help for the 59 other men, women and children aboard a wooden fishing boat that had travelled from Sri Lanka and spent more than 20 days at sea.
Australian border patrol had let the boat flounder without food, fuel or water for at least eight days before the refugees were finally rescued on May 9. But the Labor federal government has refused to call an inquiry, referring the tragedy to federal police and immigration.
