The international organisation has also claimed "Nauru is not a safe or appropriate environment to send vulnerable people, especially children," and and "reminded" the government about its obligations regarding the rights of children.

"This decision by the High Court greatly concerns us as these children and their families face a great risk in being sent to a place that cannot be considered safe nor adequate," the Committee Chair Benyam Mezmur said.

In an accompanying series of social media posts, the U.N.'s human rights division said "We urge Australia to not transfer 267 people... to Nauru," using the #LetThemStay hashtag which has been used by refugee advocates fighting to keep refugees from being taken to Nauru.

"We are concerned that... Australia’s policy on the treatment of migrants and asylum seekers arriving without prior authorisation, significantly contravenes the letter and spirit of international human rights law," read a post on the United Nations Human Rights Facebook page.

The @UNHumanRights Twitter went even further, levelling serious criticism of Australia's use of Nauru as an offshore processing centre.
