Releasing his findings on Wednesday, Coroner Simon Cooper found Mr Steffen died on or after June 17 1985, at a place unable to be determined, in Tasmania.
Mr Steffen was reported missing by his mother, and Queensland Police investigated.
But there was no evidence to suggest he was in the state, and the investigation was handed over to Tasmania Police.
The last documented evidence of him being alive was a visit to his GP in North Hobart.
He had a history of mental health issues, and while living in Tasmania, he dealth with a "Zen Buddhist" practitioner who he discussed suicide with.
It was believed that practitioner was the last person to see Mr Steffen alive.
But with no body, it could not be confirmed how he died.
"The only reasonable conclusion having regard to all the evidence carefully compiled and presented to me by Sergeant Delpero of Tasmania Police Missing Persons Unit, is that Mr Steffen is dead and that more likely than not his death occurred in Tasmania, sometime after 17 June 1985," Mr Cooper wrote.
