Mr Zivkovic uploaded a video to Facebook of him standing on the bonnet of a moving car, drinking a Carlton Dry stubbie and smoking a cigarette.

The video has thousands of likes, shares and comments, and has also attracted the attention of the Horsham Highway Patrol, who said the "nature and content" of the video were being investigated.

Mr Zivkovic said his actions in the video were less dangerous than they looked.

He said he also had five years of formal training to be a stunt man, which made the incident less dangerous.

"This wasn't just a spur of the moment thing to do something dumb," Mr Zivkovic said.

"I planned to do it, and I made sure it was in a safe, controlled environment. It was on a private road. I wasn't just getting on the beers and standing on a moving car.

"The car was barely moving. There was no throttle involved, it was travelling less than 15 kilometres an hour. It was just windy that day, so it looks faster than it was.

"And nobody was at risk except for myself."

The video is part of a new viral trend in which people upload videos of themselves lip-syncing to Fleetwood Mac's 1977 song Dreams.

The trend was started by a longboarder in Idaho, United States, who filmed himself skating to work on a freeway and drinking cranberry juice after his car broke down.

"From a safety point of view, I wouldn't recommend people try anything they see on the internet," Mr Zivkovic said.

"I don't recommend anyone put themselves in danger.

"I recognise that it was a bit stupid for some, but for me, it was all about the good times."

Mr Zivkovic said there was another reason he uploaded the video.

"I was thinking to myself, there's that many people battling with mental health out there at the moment - if one bloke looks at my video and has a smile and maybe it saves his life, then that's enough for me," he said.

"I'm a big advocate for mental health, because I've struggled with it all my life. If I can make people feel better, then I will."

Mr Zivkovic's video has since made national headlines, and has created chaos in his personal life.

"My phone has not stopped ringing," he said. "It's been crazy.

"I really never expected this. I thought I'd just do it for my mates to have a laugh."

Asked whether he regretted the video, or if he was embarrassed by the attention he received, Mr Zivkovic said: "I don't get embarrassed. If you live your life worried about what other people are saying about you, are you even living?"
