Several of the alleged victim's friends and family covered their faces in horror.

She is then pushed to the ground so hard she breaks her collarbone and is knocked unconscious.

Estabillo told the court on Thursday: "He came towards me... I had a sensation of not having my feet on the ground... I don't remember much after that... I woke up on the ground."

The confrontation began in the early hours of March 12 inside the Wynyard Hungry Jack's in Sydney.

The 29-year-old's friends got into a heated argument with another group which turned violent.

A man with the accused lashed out. Mark Ambrose Shepherd knocked one woman out cold, then continued swinging.

McFadyen faces two charges, including assault occasioning grievous bodily harm.

The hearing continues.
