HUMAN rights groups say an investigation on Nauru shows the Australian Government had "designed a system of deliberate abuse" on asylum seekers.
Amnesty International and Human Rights Watch conducted an investigation on the island and interviewed 84 refugees.
The groups said refugees and asylum seekers on Nauru routinely faced neglect by health workers along with frequent unpunished assaults by local Nauruans.
One of the researchers, Amnesty International's Anna Neistat, said few countries went to such lengths to deliberately inflict suffering on people searching for safety and freedom.
A Department of Immigration and Border Protection spokeswoman said the Department strongly rejected many of the allegations in the report.
The spokeswoman also said Amnesty International did not consult with the Department when preparing the report.
