The driver of the second vehicle, a grey sedan, was a 61-year-old woman who was taken to Wollongong Hospital for mandatory testing.

Debris was scene strewn across the intersection and the bike destroyed.

Officers attached to Lake Illawarra Police District cordoned off streets around the scene for several hours, with traffic diversions in place as forensics and specialist police scoured the area for evidence.

A NSW Police spokeswoman said no other vehicles were involved in the crash.

Mount Warrigal resident James David was awoken to a screeching sound around 5.45am, before looking out his window at the crash site.

Mr David was one of the first on scene and covered the body with a sheet. He said he still had the horrific sight of it embedded in his mind.

"The impact from the crash was so bad all his clothes were just about gone, ripped off, his jacket, his shoes," he said. "He was thrown about 15 metres away from the bike."

Having lived nearby for six years, he said accidents were a been a regular occurrence and labelled the intersection as a known "crash hotspot".

"I've seen so many accidents, even cars running right into the house next door," Mr James said.

He said motorbikes were often the culprits but cars could be seen "tearing around the corner" or down Lake Entrance Road late at night.

"If any intersection deserves a red light speed camera it's this place, because often you'll get cars racing through there late at night at incredible speeds," Mr James said.

"If it's going to save lives, that's what this needs and it's needed it for a long time."
