In a Facebook post, Ramzy Alamudi said he and his wife were getting in their car at Macquarie University on Friday afternoon when they noticed the woman staring at them.

Mr Alamudi said his wife, who had just finished her final exam in her medical science degree, noticed the woman looking at them and waved and smiled at her as they got into the car.

"This is where the entire situation just turned upside down. The lady flips it and sticks her middle finger right at us," Mr Alamudi wrote on his post.

Mr Alamudi urged his wife to get into the car and lock the doors, and then she started filming.

The disturbing footage captures the woman banging repeatedly on the windows and trying to open the doors of the car, as she points and yells "Get out" and "Who are you?"

The woman walks around the car and then starts pulling at the windscreen wipers.

"Who are you? Why you got a mask? Terrorist. You got a gun?" she is heard yelling.

"I only reacted after she was going to snap off my wipers (it was a rainy day!)," Mr Alamudi wrote.

"I moved the abusive woman away from my wife until several witnesses assisted in the attempt to neutralize her till security came."

Mobile phone footage posted online by Emily Grace Guff shows the woman continuing to yell at Mr Alamudi after he left the car, saying, "I see her looking so scary" and "I don't know what she carry".

"She was demanding this man show her some form of ID, calling out that she [Mr Alamudi's wife, wearing the niqab] didn't belong here, and that we shouldn't let her walk around freely because we didn't know what she could have hiding under her dress," Ms Gruff wrote.

"The whole time this woman was having her rant, her baby was sitting in her unlocked car, meters from where she was hurling abuse."

In his post, Mr Alamudi thanked the university security and said the kind of abuse they had experienced was not isolated.

"An unfavorable circumstance for my wife and I, However, I'm at least glad this happened to us as opposed to another innocent person who may not have been capable of defending themselves," he wrote.

In a statement, Macquarie University confirmed security officers had been called to the incident and said local police had been contacted.

"Macquarie University takes matters of this nature incredibly seriously. We are very proud of our diverse community and are committed to religious acceptance and the free expression of faith. A full review is currently under way," the spokesperson said.

Police have charged a 35-year-old woman with common assault and destroying or damaging property following an incident in a car park about 1pm on Friday.

The woman will appear in Burwood Local Court on Monday, March 13.

PLEASE WATCH!! Never in my life have I been unfortunate enough to witness such repulsive behavior from one human being to another. Getting in my car at a Macquarie University car park this afternoon I noticed an altercation between a man of middle eastern ethnicity and an Asian woman, pushing and shoving each other, both calling out for help. As myself and another bystander approach the two, we made the shocking discovery that this poor man was actually trying to fight off this woman from his wife, who was sitting inside their car behind him. This deranged woman had the nerve to attack his wife because of the burka she was dressed in, claiming she 'didn't feel safe' around people like her. She was demanding this man show her some form of ID, calling out that she didn't belong here, and that we shouldn't let her walk around freely because we didn't know what she could have hiding under her dress. The whole time this woman was having her rant, her baby was sitting in her unlocked car, meters from where she was hurling abuse. Yes, she had left her infant child in the car to run over and launch herself at an innocent couple minding their business. It makes me feel sick to know we coexist in a world where this happens so frequently, people thinking they have the right to belittle someone else because of their race or religion - to see what absolute shit some people actually have to deal with. Just listen to the garbage she kept repeating!! I'm sorry ma'am, in my opinion the only ones who don't 'belong' here are racist people like yourself who have the nerve to discriminate and abuse innocent people. That is as un-Australian as they come. First hand footage from the incident: https://www.facebook.com/ralamudi/posts/1387266844657903Posted by Emily Grace Guff on Thursday, January 19, 2017
