A 42-year-old man has died following a two-car crash at Unanderra Thursday night.
An 18-year-old man, who was a passenger in the same car, was airlifted to hospital after Fire and Rescue crews worked for hours to free him from the wreckage. He remains in a serious but stable condition.
The men were travelling in a black Nissan Skyline that t-boned a blue Hyundai i30 at speed on Farmborough Road, near the Waples Road roundabout, about 7.50 pm.
A 17-year-old boy and an 18-year-old man who were also in the Nissan Skyline were not injured.
A 55-year-old man and his 15-year-old son who were travelling in the Hyundai i30 were treated at the scene and taken to Wollongong Hospital with non-life threatening injuries.
A witness to the aftermath of the crash said the driver of the Hyundai crawled from the wreckage.
The Mercury understands the deceased man was driving the Skyline when it came unstuck off the roundabout.
A large crowd of bystanders looked on as the rescue continued into the night.
A witness to the immediate aftermath of the crash, Haylie Staff, was among those who came to the aid of the injured.
She was travelling behind the Hyundai with her partner and four-year-old daughter when the accident occurred.
“By the time we come around the [Princes Highway] traffic lights, this black car was sliding across the road to where it is now,” she said.
“The driver [of the Hyundai] was crawling to the gutter, he was very disorientated. His son was still in the car.”
Good Samaritans were joined by an off-duty paramedic. Together they checked on the injured and helped most of them out of their cars, Ms Staff said.
“The [Skyline] driver was already unconscious. His passenger was unconscious, but another gentleman here brought him around,” she said.
“The bloke behind him in the back, got him out too.
“But we couldn't do much for the driver. He passed away, pretty much straight away.”
“I was trying to keep the one that’s trapped now, calm. He was very, very scared, screaming to hurry up and get him out.”
Lake Illawarra police will investigate the circumstances surrounding the crash.
