A Sydney couple who locked themselves inside a car while a woman allegedly launched an apparent hate-filled attack at Macquarie University said the incident left them feeling "anxious".

The female victim told the University's online publication Grapeshot she was scared about returning to the uni.

"I was scared of the thought of ever going back on campus. This woman did make me feel anxious.

"But after coming to terms with it, I realised that I should not let it be something that discourages me… we need to take everything day by day with wisdom, calmness and patience."

The alleged attacker has been charged following the release of footage showing the apparent incident.

In a video posted to Facebook overnight, the woman could be seen banging on the vehicle's windows and swearing at them.

She continues to slap the car's windows, and the couple can be heard discussing whether to call security or drive off first.

The woman then grabs a windscreen wiper, before the driver confronts her.

"Who are you? Why you got a mask? Terrorist. You have gun?" the woman can be heard saying as he steps outside.

In a statement from Macquarie University, the couple are said to be “shaken” following the attack.

Police have charged the 35-year-old woman with destroy/damage property and common assault.
