A man has avoided jail over a vicious brawl that left a bride-to-be knocked out cold on the floor of a fast food restaurant in Sydney’s CBD.

John McFadyen was given a suspended sentence for assaulting 29-year-old Lauren Estabillo on her hen’s night in March.

Security cameras recorded the moment he threw her to the floor with such force she was knocked out and her collarbone was shattered.

What was meant to be a night of fun and laughter was brought to a quick end for Ms Estabillo, just two weeks out from her wedding day.



McFayden, a mine worker, had been drinking with his friend Mark Shepherd before walking into the Hungry Jack’s restaurant where the altercation occurred.



The court heard he started an argument by knocking a hat off one of the girl's heads and making sexually explicit comments.

Shepherd came out swinging inside the restaurant before the fight was broken up.



Lauren Estabillo followed McFayden outside, where he claims he was pushed and punched first.



His lawyer claimed self defence, saying: “He's entitled to go about his business, without her in effect, taking the law into her own hands.”

The prosecution responded: “It was more than a push. There was a leg sweep and she was thrown to the ground.”



The magistrate said while McFadyen can be seen backing away, he was clearly much bigger and stronger than his victim and his response was excessive.



The 44-year-old was handed a seven-month suspended sentence.
