Head-on collision kills two and injures three in Suffolk Park, northern NSW

Two people have been killed and three others injured in a horror head-on collision.

Paramedics said two cars collided along Broken Head Rd in Suffolk Park, south of Byron Bay, before a third vehicle crashed into the wreckage about 10.30am on Saturday.

Police said initial investigations indicated a maroon Nissan had been travelling north on the incorrect side of the road when it collided head-on with a white Kia sedan travelling south.

The collision happened on a section of road with double white lines and a blind corner, police say.

Emergency services raced to the scene to find the drivers of two of the vehicles had died.

They are yet to be formally identified but are believed to be a woman aged in her 50s and a man aged in his 60s.

The male driver’s passenger, a woman also aged in her 60s, was treated at the scene before being airlifted to Gold Coast University Hospital where she is fighting for life in a critical condition.

Police said one of the victims and the critically injured passenger were a recently retired couple from Western Australia.

Authorities have been in contact with family members who were also away on holidays at the time of the crash.

Paramedics told 7NEWS.com.au that another woman aged in her 30s and a teenage boy suffered minor injuries and were taken to hospital.

Crash investigation officers and forensic services are probing the circumstances surrounding the collision.

“What I would say, it’s an absolute tragic incident that’s on a weekend, it’s a beautiful day here in the Northern Rivers and it will certainly catastrophic results for the family and the community as a whole,” Inspector Matt Woods said.

The road has been closed between Beech Dr and Broken Head Reserve Rd as police investigate the crash.

Anyone with information has been urged to contact Crime Stoppers.
