A man has been remanded in custody after being charged with murder over the disappearance of Carol Clay and Russell Hill in the high country.
The pair were camping in the remote Wonnangatta Valley, about 50 kilometres south of Bright, when they went missing in March 2020.
Charge sheets allege the pair were killed by Lynn in Wonnangatta on March 20 last year.
Police have run an intensive investigation into the matter and had appealed for information about a four-wheel-drive seen in the North East about the time of the disappearance.
Investigators this week seized a vehicle and took Lynn into custody for questioning.
The 55-year-old's matter was listed for a file hearing in the Sale Magistrates Court on Friday morning.
He appeared on video link from custody, wearing a grey jumper and a white face mask.

Lynn did not speak during the matter and will return to court on May 31 next year.

Mr McLennan said there were no custody management issues.
