A man has been charged with murder after human remains were recovered from a shallow grave in a Launceston backyard.

The 45-year-old was charged late on Wednesday following the overnight discovery at the suburb of Mayfield by police investigating the whereabouts of missing man Tyson Timothy Clark-Robertson.

The 24-year-old was last seen on July 19 but was not reported missing until March, with his family telling detectives they were in contact via Facebook messenger.

"We have found human remains in a shallow grave," Detective Inspector Philippa Burk told reporters of the overnight discovery in the suburb of Mayfield.

"It is highly probable that it may be our missing person."

The accused murderer will face an after-hours court session, while a 53-year-old man has been charged with being an accessory to murder.

A 19-year-old woman is charged with failing to report a killing.

Forensic teams remain at the property, which was occupied when police discovered the body.

Insp Burk said it may take some time to exhume the remains and confirm the identity.
