A woman who was left for dead on a Sydney street has revisited the site of the hit-and-run that almost claimed her life two-and-a-half years ago.

Samantha Giufre was dragged along a Casula road by a car for about 100 metres before being flung into a gutter and left for dead in September 2014.

She suffered significant brain injures which left her blind in her right eye and partially blind in her left eye.

“I’ve still got operations to go. The pain and suffering is continuous,” Ms Giufre told 9NEWS.

“Doctors say there’s improvements. But there’s a lot of improvement to go.”

Court documents state Ms Giufre had been speaking to a passenger in the car when the man behind the wheel, Bashar Hawchar, drove away.

When the car reached an intersection, Ms Giufre was thrown from the car and hit her head on a gutter. The car did not stop.

Although Ms Giufre doesn’t remember the entire incident, she believes a passenger in the car must have held onto her as the car drove away.

“My fingerprints weren’t on the car so someone was holding onto me,” she said.

If there were others in the car, they are yet to be caught by police.

Ms Giufre spent four months in hospital recovering and learning how to walk and talk again.

Mr Hawchar has pleaded guilty to dangerous driving causing grievous bodily harm.

A judge will now decide if and for how long he will spend behind bars.

The Crown alleges he sent a Facebook message that said: “I done that b****, she deserves it and that’s what happened when you don’t pay up”.

Mr Hawchar denies he wrote the message. He apologised for the first time while leaving court today.

“I’m very sorry to her and her family,” he said.

“I acknowledge what I did was wrong and I’m paying for that.”

Mr Hawcher is due to front court again later this year.

Ms Giufre, who continues to visit doctors for treatments, said the incident “changed my life”.

“I never thought anything like this would happen.
