A Rohingya man who took his life after being "destroyed" in detention will not be forgotten, refugee activists have promised at a vigil outside Peter Dutton's office.
Almost 40 activists gathered on Thursday outside the immigration minister's electoral office, north of Brisbane, to express their outrage over the death of 52-year-old Salim on Manus Island last week.
Chalk was used to draw outlines of bodies on the footpath outside the office to mark the deaths of 11 refugees in Nauru and Manus Island with the question 'Who is next?' written alongside.
Salim died after jumping from a moving car on the island following five years on the island.
He was the seventh Rohingya refugee to die there and the third apparent suicide at the centre in less than a year.
Noor Zaman, president of the Queensland Rohingya Community, said Salim was brought to Australia in 2014 for treatment for severe epilepsy but was returned to the island soon after without the condition being brought under control.
Mr Zaman described the father-of-three as a friendly, humble man but was in pain in detention, with seizures almost every day and suffering from a deteriorating mental state.
"They destroyed his life," he told AAP.
"Salim's death was not suicide, it was murder under the leadership of Peter Dutton and Malcolm Turnbull."
Mr Zaman, who himself spent 18 years in a refugee camp, said Salim had requested medical help several times.
Former Greens senator Larissa Waters addressed the vigil by asking how many more deaths would occur before the federal government took action.
"Salim will never be forgotten," she said.
"We must close the camps; we must bring them here. It is a stain on our nation."
Mark Gillespie, from the Refugee Action Collective, said Mr Dutton needed to take responsibility.
"Salim fled genocide in Myanmar and was found to be a refugee and owed protection, but instead of safety he was condemned to five years of hell in an offshore detention centre."
