Unidentified remains are being transported to the coroner's office following an eight hour search through dense bush land.
Acting Senior Sergeant Karen Bain, of Stawell, said the two hikers who spotted the human remains on Monday led seven police members and seven State Emergency Service crew back to the remains on Tuesday.
"I think it's been hard going. From what we're hearing, they've had to go up creek lines and off track," Acting Senior Sergeant Bain said.
"It's very dense, bushy area and quite remote where they were."
The remains were located about 12.50pm near Mount Rosea Track and taken back on a stretcher to the Borough Huts Campground by foot.
"It's off the old Mount Rosea Track, that's now been decommissioned," Acting Senior Sergeant Bain said.
No identifying details have been released at this early stage.
Acting Senior Sergeant Bain said "at this stage it doesn't appear suspicious."
