Kayne Flight had been helping his brother move to Wellington and the pair were due to head back to Brisbane when their car was involved in a three-vehicle collision.

Kayne was taken to the intensive care unit at Westmead Hospital in a critical condition. His brother was shaken but avoided any serious injuries.

A total of nine patients were treated at the scene.

Their brother Sacha said Kayne had sustained serious injuries in the crash and had started the page to help his parents deal with the costs of accommodation as they stayed with Kayne during his recovery.

They have set a goal of $3000 to assist with expenses and as of yesterday afternoon had raised $250.

Sacha said any help would be greatly appreciated and any additional money raised would go to equipment Kayne would need during his rehabilitation.
