The PNG authorities have advised detainees in Manus of thir options.

In short, it comes to this: If you are refused refugee status, you will be sent back to your country of origin. If you cannot return to your country of origin, you will stay in detention in PNG.  You will not be allowed to go to Australia.

Be clear about this: people who have committed no offence will be jailed, potentially for life, if they are stateless or if they are unwilling to return to their country of origin to be persecuted.

Here is a copy of the notice.

This, coupled with processing designed to exclude as many refugees as possible, will involve forcing people badk to face persecution.  Already the system on Manus is operated with a view to breaking the spirit of the people held there, so that they will abandon their claim for protection.

Australia has disgraced itself by creating and running a system like this.
