As Robbie Cattle reached a terrified mum and two young kids who were treading water next to their sinking car, he told them "don't worry, I'm going to help you".
"One of the kids was screaming and she was panicking," he told the Herald.
"I said 'don't worry, I'm going to help you, I'm here now'."
Moments earlier he'd be driving down a Bucklands Beach Rd when he came across a group of people screaming on the side of the road. A car was submerged in water about 10 to 15m offshore.
While the exact details of how it got there are unclear, neighbours believed the car was parked in a steep driveway on the other side of the road but the handbrake might have failed.
They say a man, believed to be the woman's husband and children's father, desperately tried to stop the car as it raced down the driveway on Sunday night. He wasn't able to stop it and it reportedly hit a parked car, flew across the road and landed in deep water.
Cattle said he just reacted to the situation, pulling his clothes off as his partner told him "go, go, go".
"She was on the phone to 111 and I was already pretty much half naked," he said.
