Police have arrested four teenagers over an attack that left a Scottish man in a critical condition in Sydney's south early on Wednesday morning.
Mark Willis, 25, was with his girlfriend Jane McLean when he became involved in an argument with a group of about 10 teenagers at Rockdale train station about 3:00am AEST.
He remains in a stable condition after undergoing emergency neurosurgery.
A 13-year-old has been charged with inflicting grievous bodily harm, while another 13-year-old and two 17-year-olds are facing assault and affray charges.
They have been refused bail and will appear in Parramatta Children's Court later this morning.
Mr Willis and his girlfriend are halfway through a working holiday from Scotland.
Police say the victim's parents are preparing to travel to Sydney.
