Auburn's controversial Deputy Mayor, Salim Mehajer, will face a two-day hearing in March over allegations he intimidated the father of a Lindt Cafe siege survivor at a gym.

The 29-year-old has pleaded not guilty to intimidation over an incident last year, where fitness trainer Bruce Herat asked him to be careful not to drop the weights.

It is alleged there was a confrontation between Mehajer and Mr Herat at the Anytime Fitness gym in Burwood, in Sydney's inner west, on September 16, 2015.

It is alleged Mehajer responded to Mr Herat with an angry tirade, swearing and saying: "Don't you know who I am?"

It is alleged he then later said: "I'm going to find out where you live ... and kidnap your children."

In court this morning, Mehajer's lawyer Richard Portello said the hearing would involve nine witnesses with two for the defence.

The magistrate set aside March 23 and 24 for the hearing.

Outside court, Mehajer scoffed at cameramen as they scrambled to capture his exit from court.

"Better luck next time mate," he said to one before being driven away.

Mehajer made headlines after closing a street for his lavish wedding in August 2015.

In December 2015 the Australian Federal Police (AFP) said it would be charging Mehajer over allegations of electoral fraud.

The AFP said it received information from the Australian Electoral Commission in August 2012.

Mehajer labelled the allegations of electoral fraud a "political game" and an attempt to make him "step down".
