A young Irishman is fighting for his life after he was punched to the ground in what has been described as a wild brawl outside a Sydney nightclub.

Jason Cierans (29) from Cork was out with friends when he struck in what's believed to have been a an alcohol-fuelled attack in the early hours of the morning.

Witnesses told 9NEWS the fight was sparked when the victim's friend was accused of jumping the queue outside a nightclub.

In footage shown on Australian news TV, the young man can be seen bleeding from the mouth as paramedics attend to him on Bronte Road in the Bondi Junction area of the city.

Mr Cierans has been working as a labourer in Sydney and had recently posted on Facebook, "left Ireland five years ago today, no turning back now".

He was rushed to St Vincent's Hospital where he has undergone surgery to relieve pressure on his brain. He is in an induced coma and family in Ireland have been notified.

A 27-year-old man was charged with affray, and a 30-year-old man believed to be from Argentina has been charged with recklessly causing grievously bodily harm.

The alleged attacker was refused bail and will face Paramatta Court tomorrow.
