The family of a man reported missing more than four years ago is continuing to appeal for details of his disappearance.
Bellarine man Douglas Kally was reported missing by family in October 2008. Initial reports indicated the father of five was possibly in New South Wales, but investigators were unable to trace him.
Mr Kally also goes by the name Dragon Dordevic.
Detectives are treating his disappearance as suspicious and want to hear from anyone with information about Mr Kally's movements around the Indented Head area, near Portarlington, during in July and August 2008.
Mr Kally's family are expected to appear at a press conference on Sunday.
Homicide squad Detective Senior Sergeant David Snare said police "desperately" wanted to solve the case to give Mr Kally's family closure.
“Someone out there knows what happened to Mr Kally and we are urging them to contact police,” Detective Senior Sergeant Snare said.
