Police said they were advised the man had died, and a report will now be prepared for the coroner.

Police said the 18-year-old man had been freed by emergency services after he collided with several cows which had strayed onto the road. He was airlifted to John Hunter Hospital in a critical condition.

MONDAY, MAY 31: A motorcyclist has been flown to hospital after crashing his bike into cattle near Coonabarabran.

About 1pm on Friday a group of motorcyclists were travelling north west along Wyuna Road, Nombi, about 45km east of Coonabarabran, when they

navigated through a signposted livestock grazing area.

It is believed one rider, a 36-year-old man, collided with livestock on the roadway causing him to be ejected from the motorcycle.

He was treated at the scene by paramedics before being airlifted to Tamworth Base Hospital in a stable condition.

Officers attached to Orana Mid-Western Police District attended and started inquiries.

The incident comes a day after an 18-year-old man was critically injured when the car he was driving hit cattle on the Thunderbolts Way at Yarrowyck, about 30km from Armidale on Saturday night.

Shortly before 9pm on Saturday, an 18-year-old man was driving a Ford Meteor northbound on Thunderbolts Way, Yarrowyck, about 30km north-west of Armidale, when he collided with several cows which had allegedly strayed onto the road.

The vehicle left the roadway and crashed into a ditch, trapping the man by confinement.

Emergency services attended and he was released.

He was treated for head and internal injuries and airlifted to John Hunter Hospital in a critical condition.

Officers attached to New England Police District attended and started an investigation.

The incidents have prompted police to remind the public of their responsibilities surrounding livestock on public roads.

Rural Crime Prevention Team, Acting Detective Inspector Damian Nott, is reminding livestock owners and the public alike of their responsibilities when it comes to livestock on public roads.

"As a stock owner, you are responsible to safeguard against your stock straying onto public roads; that is to ensure boundary fences are stock proof and the Biosecurity Act 2015 is adhered to," he said.

"If your stock stray onto a public road and are a contributing factor in a motor vehicle accident, you may be charged with a criminal offence."

Acting Detective Inspector Nott said motorists also have a role to play in reporting straying stock and driving to the conditions when passing through a signposted stock zone.

"If you're a motorist who disregards a signposted stock zone and fails to give way to livestock travelling along public roads and travelling stock routes, you may face hefty fines or in some instances face traffic offences such as negligent driving or failing to give way," he said.
