Former Auburn Deputy Mayor Salim Mehajer has been given a three-year good behaviour bond and ordered to undergo anger management counselling after pleading guilty to assaulting a taxi driver.

The 31-year-old admitted throwing an EFTPOS machine in the face of a taxi driver, causing injuries to the driver's face.

He also pleaded guilty to damaging a woman's phone after she filmed him outside The Star casino in April last year.

Mehajer appeared at the Downing Centre Local Court via video link while in custody on an unrelated matter.

Magistrate Vivien Swain told the court that Mehajer "needs to keep control in a stressful situation".

She ordered him to pay compensation of $459 for the damage to the woman's phone, and $155 for damage to the EFTPOS machine.

"I note that somebody else in the group took the phone and deleted the video," Ms Swain said. "Then Mr Mehajer took the phone, threw it on the ground and smashed it."

She noted that it was a "very late plea", but said there was some value in the plea, as it removed the need for the victims to appear in court and be cross-examined.

Ms Swain said that the damage to the property and the assault offence fell into the mid-range level of seriousness.

"I note that the taxi driver is classified as a vulnerable person," she said, adding that he should have been entitled to feel safe while working.

Magistrate Swain said the offence seemed to happen "in the spur of the moment" after Mehajer had a "loss of temper".

She noted that at the time of the offence, he had no criminal record, although he has since been convicted of assaulting a journalist later that day.

But she said that matter had not been an issue in her determination of this case.

Earlier, Mehajer's Barrister, Philip Bouton, SC, told the court that his client had "an overwhelming desire not to be in trouble anymore".

Mehajer had been due to appear in court over this matter on October 16, when he was involved in a car accident and was unable to attend.

Mr Boulton, told the court that Mehajer was with colleagues at the casino when he was filmed by a woman.

"The idea of being filmed in an unwelcome way was something that caused him concern," Mr Bouton said.

"He lost his cool because of the filming. "It can simply be said to be a loss of control which he regrets."

The court heard the group then flagged a taxi and that a member of the group gave the driver, Nazir Syed, $200 to take them around the corner.

A dispute over the money given to the driver followed and Mehajer "grabbed hold of the EFTPOS machine as some type of leverage" and eventually threw it at the Mr Syed, who received injuries to his face, Mr Boulton told the court.

Mr Bouton said Mehajer "did not intend to hurt him" and that his client did not "think enough about his actions".

"He regrets what he did," he told the court.
