Gympie man Jayden Alexander is believed to have been involved in the serious accident near Traveston last Thursday night, but he was not found near the scene.
Inspector Pat Swindells said police had contacted friends, family and associates in their search for the 28-year-old.
“It would appear that it was a very heavy impact,” he said.
“Part of the investigation that’ll be launched as a part of this will be if speed was involved, driver condition, car condition, road conditions.
“Family raised concerns with police over the weekend. We ramped up those investigations as of the weekend because he couldn’t be located through conventional means.
“We came back down here to the initial crash site to try and work out his movements from there.”
The SES and police teams, supported by Polair have been searching Cobbs Gully near the Bruce Highway at Kybong.
“We have Polair actually conducting a search, SES personnel, police personnel, police on motorcycles and the major organised crime rural were bringing horses over to assist in the search,” Inspector Swindells said.
Mr Alexander is described as Caucasian, about 180cm tall, and of slim build with brown hair and blue eyes.
Anyone who may have seen him or has further information is urged to contact police immediately.
