But he never made the flight and has not been seen or heard from since.
O'Byrne said she has serious concerns for his health in a public appeal for information.
She shared a photo they took together at Kelmscott Dome before heading to Perth Airport, before he went missing.
Carter is described as about 174cm tall with a slim build, brown hair and blue eyes.
Anyone who has information on his whereabouts is urged to contact police on 131 444.
