Detectives investigating his disappearance raided a business at Coopers Plains in Brisbane's south on Thursday morning.
A mobile police unit remains at the scene with detectives set to make a public appeal for information later in the day.
"Anyone with knowledge of his whereabouts or information about the missing person is urged to contact police," a police statement said.
Mr Griffiths is Caucasian with sandy hair and hazel eyes and has tattoos on his neck.
