New Zealand detainees' attempts to get released from an Australian detention centre have been set back by a heavy-handed crackdown, advocates say.
Kiwis at the Christmas Island facility are now unable to reach lawyers or family because cellphones have been confiscated and other communications shut off.
Lawyers said this made it impossible for the detainees to appeal their Australian visa cancellations or apply to return to New Zealand.
There were also concerns about detainees' treatment after a three-day riot was shut down at the facility. Some of them were now said to be sleeping in the dirt and without access to basic facilities such as toilets.
