A refugee advocacy group says there have been two more suicide attempts on Manus Island.
An Iraqi refugee who attempted suicide on Manus Island is being held in a police cell as he recovers, according to an advocacy group.
Refugee Action Coalition spokesperson Ian Rintoul, who is on Manus Island, told SBS News the man attempted to harm himself on Tuesday, with local police putting him in a cell as "there was nowhere else that is suitable or secure".
"Anywhere else but Manus Island, it would be unbelievable that someone who is having a mental health crisis is actually confined in a police cell," he said.
The man allegedly had access to health professionals from contractor Pacific International Hospital (PIH).
"There no crime - it's only because of his mental health situation and he attempted suicide and that's why he's been placed there," Mr Rintoul said.
"Police said he will not be released until a PIH psychiatrist gives the all clear ... [This is] a disgraceful extension of PIH hospital facilities."
Mr Rintoul said a Somali man also attempted suicide on Wednesday and he is now in a health facility.
"These are just the most recent examples of the mental health emergency on Manus Island. The Australian government needs to act," he said
SBS News has contacted the Department of Home Affairs about the two cases and the quality of mental health care on the island.
The regional processing centre on Manus Island's Lombrum Naval Base closed in 2017 but there are about 600 refugees living in camps in the main town of Lorengau.
The offshore policy is designed to deter people embarking on treacherous sea journeys, but the United Nations and other rights groups have long criticised the camps' conditions and the long detention periods.
