The government of Victoria will ban the sale of machetes starting Wednesday after a violent gang fight at a shopping mall in Melbourne.

Premier Jacinta Allan announced the immediate ban on Monday. She said the state would use consumer law powers to stop the sale of machetes until a full ban on possession takes effect on September 1.

“We will be bringing in place a ban on the sale of machetes here in Victoria and this ban will be in place from midday on Wednesday,” Allan said. “These knives are dangerous weapons. They have no place on our streets.”

The new rule bans the sale of machetes, which the government defines as knives with blades longer than 20 centimeters. Kitchen knives are excluded. 

Consumer Affairs Minister Nick Staikos said the ban will be enforced with inspections and could result in fines over $200,000 or imprisonment for retailers who violate it. He said no exemptions will be allowed under the interim ban.

Victoria’s decision follows a brawl on Sunday afternoon at Northland Shopping Centre in Preston, a northern suburb of Melbourne. Eight people, believed to be members of rival youth gangs, fought with machetes in the mall’s food court.

A 20-year-old man was hospitalized with serious head injuries following the incident. Police said three machetes were recovered at the scene. 

Two teens aged 15 and 16 were arrested at the scene and were charged with affray, causing injury, and possessing a controlled weapon. They were remanded to appear at the children’s court.

Two others, aged 18 and 20, were arrested on Monday and were also charged with affray and causing injury. They were released on bail and will appear in court in July.

Victoria is the only Australian state planning to ban machetes. In September last year, England and Wales implemented a similar ban.
