A man has described the moment he pulled three teenagers from a burning car after a crash in Sydney's south-west.
He was one of several witnesses that risked their lives to help after a Subaru and a Lexus collided on King Georges Road in Roselands.
The Subaru hit a tree, ploughed into a fence and burst into flames before 10pm last night.

An 18-year-old driver and her two teenage passengers were still inside the burning car when neighbour Michael Rose rushed to their aid.
"I pulled the girl out of the car straight away," Michael said.
"I ran around to the passenger, having a hard time pulling her out, we bent the seat belts around and pulled her through, whatever way we could get her out."
It was then that Michael noticed a third passenger still trapped in the back seat.
"His head popped out through the air bags," he said.
"He's going, 'Please mate! Get me out!'"
Michael's brother Robert Rose also stepped in to help.
"I heard a lot of screaming, I was trying to get a hose," Robert said.
"I didn't know whether it was gonna blow up or not."
