And you can sense at that exact moment, Vice Admiral Griggs' heart broke.
Vice Admiral Griggs' full response to the question.
"I don't believe there is any evidence that that is a likely course of action. One of the things we have playing to our advantage is our geographic isolation and the length of time that it takes simply to get to Australia. And the life cycle of the virus it becomes very obvious... how sick someone is. I think the ability to inject someone into the country that is not showing symptoms is quite difficult."
TL;DR
no.
