During the brief hearing she yelled over the phone: “You know I’ve got a child out there and an injured partner.”
Ms Harper was remanded in custody to reappear on February 15.
Meanwhile, detectives are hunting 40-year-old Benjamin McCartin, who is wanted for questioning over the fatal brawl.
“Police have a number of follow-up inquiries to make in relation to another man who is believed to be involved and remains outstanding,” a police spokeswoman said.
A third man – a 42-year-old from Melbourne – is fighting for life in hospital after being found at the bottom of a fire escape with critical injuries hours after the brawl.
At 3am on Sunday emergency services were called to treat a man found at the base of a fire escape at a King Street hotel.
Police were told the injured man had fallen, but the police spokeswoman said detectives were investigating if his injuries were linked to the stabbing.
Mobile phone footage of the aftermath of Saturday’s brawl showed a blood-soaked footpath near the intersection of King and Bourke streets as bystanders rushed to assist the injured man.
When one man yells, “Is he all right?” a woman leaning over the injured man replies, “Nah.”
Hours later forensic officers were seen removing a number of knives from the nearby area while officers from the Critical Incident Response Team combed the city streets.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
