Queensland state coroner has handed down findings as to whether the death of Iranian refugee, Omid Masoumali, on the island of Nauru could have been prevented.

Mr Masoumali suffered significant burns after setting himself alight in front of a United Nations Delegation five years ago. 

The inquest heard that just the day prior, Omid asked the local clinic for mental health help, and was scheduled to see a psychologist. 

The coroner recommended the Commonwealth work with the government of Nauru to improve communication with asylum seekers, to provide more certainty to refugees in their asylum applications.
