Human remains have been found in dense bushland near an area being searched for a missing man in Western Australia.

Police say a member of the public alerted local officers to the discovery near Nannup, about 265km south of Perth, on Monday.

Detectives and forensic officers were at the scene on Tuesday working to identify the deceased person.

"At this time it is not appropriate to speculate whose the remains may be," Inspector Geoff DeSanges told reporters.

"However, the remains were located close to a search area for a man who has been missing since 2021."

No suspicious evidence was found and investigations continue.
