Police are seeking public assistance to locate a 64-year-old man last seen at Rosedale, north of Bundaberg.
Colin Geary has not contacted family since January and has connections to the Gold Coast.
He is known to lead a nomadic lifestyle and his last known location was at a caravan park on Newtons Road, Rosedale in January.
Colin was reported missing on March 25 and extensive enquiries by police have failed to locate him.
Family are concerned for his welfare as his disappearance is out of character.
Colin is described as tanned complexion, approximately 175cm tall, medium build with light brown hair and brown eyes.
Police believe Colin may have been travelling west from Rosedale in a white Toyota Landcruiser with Queensland registration 058FQV.
Investigators are appealing for Colin, or anyone with information regarding his whereabouts, to contact police.
