“It's a big operation,” he said. “The State Health Incident Control Centre and ... police commissioner continue to work with airlines to try and work out the best way to get these people home.
“These people have done 14 days of isolation, they want to get home, we want to get them home to their families and their friends.
“We need the airlines to help us with this, we need the airlines to step up and to make their assets available so that we can get these people home.”
Mr Cook said the process was complicated with the issue spanning across the world, with cruise ships caught up in the problem.
“There’s obviously Western Australians and Australians overseas on cruise ships trying to get home as well,” he said.
“So, to a certain extent this is part of an international effort and an humanitarian international effort.”
Mr Cook said in the case of foreign cruise ship passengers and crew members in WA hospitals and hotels, the state was simply supporting the commonwealth government in the view that it was a global effort to support each other.
