In a now-viral video, Carr can be seen fly-kicking the motorcyclist, who lands hard on the concrete road.
He then throws himself at a moving car as locals continue to chase him.
Albert Daniel Voggy Rifaldo Subratha, who filmed the video, told Detik that it took 10 people to subdue Carr with a hose.
He was then taken to Kuta police for questioning, and later, the hospital for treatment.
Carr sustained bruises and cuts and required stitches on his right arm.
Meanwhile, the motorcyclist, identified as I Wayan Wirawan, suffered abrasions, bruises, and cuts, according to Brisbane Times.
Speaking to 9News, Carr claimed that he had drunk too much prior to his rampage and apologized for causing trouble in Bali.
“I was very drunk. I apologise, I don’t remember anything at all. I just want to apologise to everyone, to the victims, to the Bali people, to anyone affected by this at all.”
Carr claimed to have been drinking more than 10 bottles of vodka, as well as cocktails, ahead of his hooliganism.
“From the hospital examination, [results] showed that he had consumed alcohol, which he said included 20 bottles of vodka. This had him heavily intoxicated,” said Chief of Kuta Police Teuku Ricky Fadliansah, according to Merdeka.
Witnesses claimed that Carr also broke into a convenience store, stole the clerk’s phone, broke the window of a restaurant and assaulted a local man in his home, leaving him locked up with injuries in the arm and leg.
According to Vice News, the Australian national faces charges for destruction of property, violence, and battery, with each carrying maximum prison time of two years and eight months.
