If an Alien landed today in Australia...
1) Detain the alien in a concentration camp on a remote Pacific island without access to legal assistance
2) Impound the vessel on which the Alien arrived and destroy it to deter others from making the same journey
3) Determine that the Alien is not a genuine refugee
4) Insist that the Alien return to its place of origin (although item (2) ,akes that a little difficult.
5) When (4) fails, detain the Alien indefinitely in the camp without any possibility of release.
That's the way the Australian Government is treating human visitors who arrive unexpectedly.
