The man, 18 and a male companion, 22, were in a hired truck which they were returning to Sydney from the Gold Coast when it allegedly struck Ms O’Nair on a bridge throwing her over a guard rail on to unused railway tracks below.
Ms O’Nair’s body was discovered in heavy scrub after a member of the public attended Byron Bay Police Station and handed in part of a pushbike found badly damaged beside the highway’s southbound lanes about 5km north of the Byron Bay interchange.
A crime scene was secured by local police and specialist officers from the Ballina Crash Investigation Unit called in to carry out inquiries into her death.
Police later questioned the 18-year-old driver of a truck found parked a short distance away in Woodford Lane, Ewingsdale.
The truck had sustained significant front end damage.
It’s alleged the driver of the truck fell asleep at the wheel.
Anyone who witnessed the incident is urged to contact Byron Bay Police Station or Ballina Crash Investigation Unit via Crime Stoppers on 1800 333 000.
Ms O’Nair, who lived at the Gondwana Sanctuary at Tyagarah, was well-known as a laughing yoga practitioner, fairy and children’s face painter.
With a strong Buddhist background, she was also a non-violent communications trainer.
