A father and son died in a head-on crash north of Grafton last night.
About 9.10pm, a Holden Commodore and a Toyota station wagon collided head-on along the Summerland Way, approximately 40 kilometres from Grafton.
The 23-year-old driver of the Commodore died at the scene, while his 48-year-old father died after being airlifted to Lismore Base Hospital.
Both men were from Grafton.
The driver of the Toyota and sole occupant, a 35-year-old man, was airlifted to Lismore Base Hospital with significant injuries.
He remains in a serious but stable condition.
The road was blocked in both directions until a short time ago, while crash investigators from Ballina examined the scene.
They are appealing for anyone who witnessed the crash to contact them via Crime Stoppers on 1800 333 000.
