Australia asylum: Why is it controversial?


On 7 July Australia confirmed it had returned 41 asylum seekers intercepted at sea to Sri Lankan authorities, after an on-water screening process.

That incident has renewed international concern over Australia's asylum policy, which has grown tougher in recent years.

Australia now places those who arrive by sea in camps in Nauru and Papua New Guinea (PNG).

Violence broke out at a processing centre on Manus Island in PNG in February 2014, leaving one detainee dead and dozens injured.
