The carjacker got away with Peter Steer's vehicle, but not his camera.
"I wanted to get that shot of him with the gun, but I didn't want to get shot," Steer said.
The unnamed suspect was later apprehended by police and is undergoing psychiatric evaluation.
He allegedly attacked his wife and then fled the scene with a gun, at which point he flagged down Steer's news van and spoke to him for about 30 minutes before carjacking him at gunpoint.
During their exchange, Steer reportedly called the Australian equivalent of 911 twice.
Steer recorded the carjacker driving off, and then his takedown by police at a nearby gas station. The suspect is accused of attempted murder, possessing a weapon, robbery and dangerous driving, according to reports.
