Australian police are fed up with being bullied by a growing rate of petty criminals thrusting smartphones in their faces and creating hostile confrontations.

Queensland Police Union president Ian Leavers told ninemsn officers faced antagonistic offenders who were increasingly whipping out their phones to film a run-in with police, making it "increasingly difficult and stressful" for officers to do their jobs.

It comes as new video emerges online showing a Victorian man, who is being booked for alleged speeding, antagonising police and filming their reactions in a protracted roadside debate.

Facebook user Kevin Mack posted the video to the Australian Police Corruption page with the description: "The Victorian police are currently trying to break the law and I have just caught them red handed."

In the footage, an irritated Mr Mack asks the two officers who pulled him over to show him proof he was speeding and spends several minutes trying to provoke them into an argument.

"So you're estimating me at a speed 25kms over the limit but you can't prove to me that speed and you're going to issue me a ticket on that?" Mr Mack says.

"So do you have a speed radar in your eyes? I'm confused."

The officers react calmly, telling him the estimation is made based on the radar reading and their experience on the job.

A Victoria Police spokeswoman told ninemsn no fine was issued to Mr Mack, but could not comment on the reasons for the decision.

She said police, especially highly-trained highway patrol officers, were well within their legal rights to estimate speeds of alleged offenders.

Mr Mack has not replied to attempts by ninemsn to contact him.

Mr Leavers told ninemsn incidents like these often frustrated police.

"They're just making it more difficult and trying to antagonise police," he said.

"No other employee would have to put up with this and it's just frustrating that people would want to do this to police officers."

Mr Leavers said the public often forgot police officers were not robots and sometimes struggled to cope by the end of a shift.

"We see the best and also the worst human behaviour has to offer," Mr Leavers said.
