Detectives have released a Comfit (computer image) of a man to appeal for public assistance to identify the deceased man who was located in the Maroochy River on November 30, 2023.
Police are asking people to report any friends or family members that they haven't seen in the past week who match the description.
The man is described as 189cm tall, heavy-set build with very short brown hair.
While the man doesn't have any tattoos or other unique identifying features, he does have internal surgical nails in his right knee.
He was found wearing a black t-shirt, black shorts with thin silver pinstripes down the rear of the legs and two cream coloured knee compression sleeves.
Detectives are also interested in any property found in the river or on its banks, such as shoes, or any vehicles parked in the vicinity of the river that have not moved in past week.
Investigations suggest that the deceased may have been in the water for three to five days before he was discovered.
Detectives also believe the deceased is likely to have entered the water between Chambers Island and west of the Talep Bridge (Maroochy River).
Police were initially called to a site under the bridge at 8.30am on Thursday, November 30, after a member of the public discovered the body in the water.
Anyone with information to assist the identification process is urged to contact police.
