Police have released more images of a 34-year-old man, who has been missing from Doonan since Sunday 12 May.
Dennis Cole, known as Danny, was last seen at an address on Sunrise Road but has not been seen or heard from since.
It is hoped the images might prompt recognition from someone who might have seen him.
A search and rescue was conducted by police and SES on 18 May and 24 May in the Doonan area, but so far, there has not been any sighting of him.
Police believe he is known to visit the Yandina Forest, Wappa Falls, Cooran and Pomona areas.
Dennis is described as Caucasian, around 183cm tall, with a proportionate build, brown hair and brown eyes.
Police are appealing to Danny, or anyone who knows where he is, to contact police.
