The crash was captured on CCTV.
Grainy footage shows the car, which had a green light to proceed, slowly accelerating into the intersection. Soon after, a motorbike zooms into view, smashing into the side of the car. The force of the impact spins the car nearly 180 degrees.
Smoke rises from the wreckage of the motorbike, which comes to rest in the middle of Centennial Avenue. The car slowly turns left and drifts off the road and up over the curb.
The motorbike had caught the attention of police shortly before the crash, when it was seen speeding through a red light as it turned onto Centennial Avenue from Epping Road.

Superintendent David Driver from NSW Police said a police car turned on its lights in response, but the bike accelerated out of view.
"When the cycle accelerated away the police did not engage the pursuit, however it [the motorbike] continued on and the police drove across the crash a short time later," Mr Driver said.

"It would appear that a motorcycle rider has gone through a red light at excessive speed and collided with a vehicle at that intersection."
Witness Indranal Ghose described the motorbike as travelling at "supersonic" speed along Centennial Avenue.

"I was just about 300 metres away and I saw one bike was passing through like a supersonic," Mr Ghose told journalists.
"He was probably riding at around 130 [kilometres per hour] or something, and it was a red light," he said. "So I beeped the horn to warn him, so that he can stop."
Mr Ghose watched as the motorcycle ploughed into the car door and became "smashed completely".
"The car was going down the hill so I tried to get out and tried to stop the car, and was doing a bit of CPR with the other guy because I noticed the bike rider, he was instantly dead, probably," Mr Ghose said. "I couldn't feel his pulse or nothing."
One resident who lives near the crash site told Fairfax Media said there was an enormous impact, with a noise so loud anyone would have thought there had been at least three cars involved.
"I was a bit surprised because there was a police car flashing and I thought 'god that was quick'," the resident said. "When I got out there people were giving CPR to two people."
The resident said while locals were shocked by the fatal accident, the intersection where it happened is a "dodgy corner".
"The motorcycle wreck looked like it was on the spot where it hit," they said.
"What's dangerous about this stretch of road is it's pretty straight from Centennial Avenue all the way to those lights."
On Saturday, Mr Wong's family visited the crash site and paid tribute to the father of three.
Police are urging anyone with information about the crash to contact them via Crime Stoppers, on 1800 333 000.
A report will be prepared for the Coroner.
