Refugee advocates have claimed a 34-year-old Iranian man was attacked with a machete by two Nauruans over the weekend in an unprovoked attack.
Ian Rintoul, from the Refugee Action Coalition, said the the man was forced to stay indoors after the attack.
"What made it even more concerning was the following day the same men come back to the house that he shares with his wife and actually attacked the house that they were living. They were forced to barricade themselves in the house to defend themselves."
In a Nauru police said they received a complaint about an attack but added the complainant refused to allow a physical examination to take place.
The police said there was 'no obvious physical evidence of any attack', and that they 'conclude that this complaint was made for media exposure only and has no basis'.
The claim is the latest in a series of allegations of ongoing violence made by asylum seekers on Nauru.
Nauru's Education Minister Charmaine Scotty has the country's schools attended by asylum seeker children over allegations of abuse. A video released earlier this year purportedly shows children saying they had been hit by teachers and bullied by other students.
"Sadly there's been a misconception about the education system of Nauru. I've also read in the Australian media that they say in some instances child abuse is state sanctioned and it's an affront to us, to the people of Nauru and the education department," Ms Scotty said.
She also referred to Nauru being a signatory to the UN Convention on the Rights of the Child.
Afghan born Mohammad Ali Baqiri, who spent three years in detention as a child - including on Nauru, told SBS resources were limited and local resentment remained high.
"There was always something happening, there was always some fights happening in that school. Arguments so we were not welcome at all to be in that school for some reason."
The latest unrest follows recent concerns over the alleged bashing of two gay Iranian asylum seekers on the island and the announcement by Foreign Minister Julie Bishop of the possible plan with Iran to send Iranian asylum seekers back home.
Lawyer for the two gay men, Anna Brown from the Human Rights Law Centre, said returning to Iran isn't an option for her clients.
"It would be incredibly dangerous for them to go back to Iran. Where they would face public execution potentially for being gay."
The Department of Immigration and Border Control declined to comment.
