Gearóid Walsh died in hospital four days after he was assaulted in Sydney

A man has been charged by Australian police with the manslaughter of a 23-year-old Irishman who died four days after he was assaulted in Sydney.

Gearóid Walsh from Dublin fell and hit his head on the ground after he was punched during an argument at a takeaway food shop on Sunday.

He sustained serious head injuries and was put on a life-support machine, but he died on Thursday.

A 28-year-old man was refused bail and will appear in court again on Saturday.

He was charged with manslaughter, reckless wounding and assault occasioning actual bodily harm.

The man presented himself at a police station following an appeal from Mr Walsh's mother, who said the family did not see the death as murder.

Tressa Walsh said: "We don't want him to serve time in prison. I think he was just very, very unlucky.

"We don't want him to torture himself over this."

It is understood Mr Walsh arrived in Australia a month ago and had been staying with a brother and sister who live there.
