Incredibly, a 5-year-old boy survived the crash with only minor injuries.

A five-year-old boy remains in hospital after he was found wandering in bushland, surviving a crash that killed three men including his father and grandfather in NSW's Hunter region.

The incident occurred at Gundy, north of Muswellbrook, in inland NSW. Police said three men had died after their car rolled down an embankment, but that a five-year-old had been found alive.

The crash occurred on private property, and was believed to have happened earlier on Monday. The child may have been wandering the scene for some hours.

The ABC reported the third man in the car was a local real estate agent who had been showing a property to the Sydney men. The alarm was raised after the group failed to return from the viewing.

"The car was located by a neighbouring landowner about 5pm and appeared to have rolled down an embankment," NSW Police said in a statement.

Police said all occupants were ejected from the vehicle, with the three men located dead at the scene. The boy was said to have suffered a broken arm, among other minor injuries, in the crash and has been taken to hospital for treatment.

The boy was surrounded by family at Newcastle's John Hunter Hospital on Tuesday, where he was receiving treatment.
