But about 9:30am, he said he was shocked to see the crash unfold.
“A BMW came around the corner, it was revving a bit, and it ran into a group of people,” Mr Prior told the ABC.
“We’ve had a bit of rain here and weather played a part in it.
“I saw some young kids go flying, and people running to help the victims. Everyone was yelling and hysterical, yelling at the driver.
“They were screaming for help.”
Mr Prior said there was only one police officer on site and he quickly joined the effort to help the victims.
“But I wish there had been more police around. This could have been avoided if more police were in sight,” he said.
“The mood is very deflated at the moment. I can’t help but think of the victims.”

“I also want to thank emergency services, including police and ambulance, who are responding to this tragedy.
“We’ve seen how this grand final has brought Newcastle together, and I hope the whole community remains united as we continue to respond.”
Prime Minister Anthony Albanese said he has reached out to Mr Minns to offer assistance.
He said he focus of the weekend should be on rugby league and should have been a day of “excitement and pride for Newcastle fans”.
