This poster was not issued by the Australian Government however
the liberals / coalition are currently pushing to have a law similar to this put in place asap
and labor is planning to block it in the senate.

The real posters are not printed in English.
Most refugees from Syria, Iraq, North Africa (whether legal or illegal)
can't speak English let alone read it.

Those who have already made it to Christmas Island and were transferred to Naru
are now being sent over to Cambodia, due to a multi-million dollar deal between
the two governments. So even as we speak, they're not being moved on to Australian soil.

While there are refugees, there will always be argument for
letting them in or keeping them out.
