They wouldn't make it to Australia. The government would force them to Nauru or Cambodia where they would be locked up in basically a prison until the tried to commit suicide or were beaten/raped by staff. Or until they gave up and decided to go back to where they came from.
Australia truly is a lovely, compassionate country.
Most Australians and Italians would object to this. Unfortunately most White Christians are irreparably racist. I would suggest a tolerant liberal nation like Israel as the destination.
