A car driven by journalist Jessica Rowe has caught on fire outside Kambala Girls School in Sydney’s Rose Bay.

The car caught ablaze on New South Head Road this afternoon while Ms Rowe was picking up her daughter from school.

Both Ms Rowe and her daughter are unharmed. The pair managed to escape the vehicle before flames consumed the car.

It’s not known what started the fire.

Channel Nine’s news anchor and husband to Ms Rowe Peter Overton told Jim Wilson on 2GB that a good Samaritan who drove one of the school buses rushed to the car when he saw smoke.

“There was a bloke who got Jessica and Allegra out of the car, he told them he saw smoke and told them to get out,” Mr Overton said.

“Fire and Rescue and ambulance and police were there. They’re all okay and they’re home now. There was a real fear that the car could’ve exploded.

“I’ll find out the bloke’s details and get in touch to give him a very big thank you.”

Mr Overton said he was en-route home to comfort his family. His colleague Mark Burrows will anchor the Channel Nine news at 6pm tonight.
