As I said before asylum seekers could board a plane and fly to Sydney without problem because the Australian visa wouldn't be checked at departure. At Sydney airport they would ask for refugee statis and Australian officials would have to investigate to determine refugee statis. The reason this approach is not popular is because at departure their passport and boarding pass would be checked nothing more. An asylum seeker holding a passport is at a great dissadvantage because checks can then be made of that persons claims.
What's your source of information about asylum seekers? A comic book?
What makes you imagine that all asylum seekers even have a passport?
It takes long enough to get one in Australia. Do you really think it would be easy to get one in a warzone?
