Just before 8.30am on November 3, NSW Ambulance responded to reports of a man in his 50s trapped underneath his vehicle on Taylor's Arm Road at Thumbs Creek west of Macksville.

Two crews and the Westpac Rescue Helicopter were dispatched to the remote scene.

On arrival, paramedics treated the 52-year-old who was suffering from a serious leg injury.

He was transported by air to Port Macquarie Base Hospital in a stable condition.

"It really is a miracle that he's survived close to 16 hours trapped on a steep embankment, mostly in the dark of night, in relatively cold conditions," NSW Ambulance inspector Susan George said.

"He's very lucky a nearby resident drove by when they did and assisted him until paramedic crews arrived.

"Emergency services crews did a great job securing the scene to release the patient and he was flown by Westpac Helicopter to Port Macquarie Hospital in a stable condition."
