SYDNEY - The United Nations on Friday said it was "troubled" by Australia's decision to send asylum-seekers arriving by boat to Papua New Guinea given conditions there failed to adequately protect refugees.
In it's first assessment of the hardline policy announced a week ago by Prime Minister Kevin Rudd, the United Nations High Commissioner for Refugees said it was concerned greater numbers of asylum-seekers could be sent to the poor and developing nation.
"UNHCR is troubled by the current absence of adequate protection standards and safeguards for asylum-seekers and refugees in Papua New Guinea," it said in a statement.
Australia resumed sending asylum-seekers offshore to PNG's Manus Island and the Pacific state of Nauru in 2012 in a bid to deter record numbers of asylum-seekers arriving by boat. Hundreds have drowned making the perilous journey.
But under the new arrangement, which the UNHCR said raised serious, and so far unanswered, questions, they will not only be processed in PNG but permanently resettled there if found to be genuine refugees.
Rights groups have already criticised the state of facilities on Manus and Nauru, and the UNHCR said there were also legal considerations.
"UNHCR's assessment, based on recent visits to PNG, is that there are currently significant shortcomings in the legal framework for receiving and processing asylum-seekers from Australia," it said.
"These include a lack of national capacity and expertise in processing, and poor physical conditions within open-ended, mandatory and arbitrary detention settings.
"This can be harmful to the physical and psycho-social well-being of transferees, particularly families and children."
The UNHCR said while problems were being addressed, it was "concerned at the prospect of further transfers taking place under the new (arrangement)... in the absence of appropriate protection guarantees and to what will remain temporary facilities on Manus Island for the foreseeable future".
It also criticised the plan to resettle foreigners - many of whom are from Iran, Sri Lanka and Afghanistan - into the socio-economic and cultural life of Papua New Guinea.
The UN concern follows that of the Australian Human Rights Commission which on Thursday said Canberra risked breaching Australia's legal obligations with the controversial policy.
"The Commission has repeatedly made clear its concerns that third country processing and the conditions on Manus Island may violate fundamental human rights," president Gillian Triggs said.
Australia has battled to stem rising numbers of asylum-seekers arriving by boat in recent years, with more than 15,600 coming this year alone and more than 750 since Rudd announced his hardline policy.
