"We welcome today's unanimous decision of the court, which has found that individuals who are not cooperating with their own removal are able to remain in immigration detention until they are removed from Australia," he said.
"Community safety continues to be our highest priority and we will continue to take all necessary steps to keep Australians as safe as possible."
