A leading Perth neurosurgeon who has seen an increase in one-punch related injuries has backed boxer Danny Green's campaign to put an end to mindless violence.
Professor Neville Knuckey, head of neurosurgery at Sir Charles Gairdner Hospital, said it had become normal for his department to treat one or two one-punch victims every weekend.
"We're seeing a lot of it where people have been violently attacked," Professor Knuckey said.
"It is a serious problem . . . It's usually young males and for the vast majority, alcohol is involved."
Professor Knuckey said the 2009 introduction of tougher one-punch laws apparently failed to stem the violence and alcohol seemed to be the main factor behind attacks.
He said having someone with Green's profile taking a stand would help educate the community.
"It's obviously beneficial to bring it to the fore and emphasise that it's a serious problem," he said.
"When you consider these are young men … their whole life has been rearranged. And it comes at a great cost to the community."
His comments came as Green revealed a 30-second advertisement he pitched to the State Government was part of a wider campaign with another four TV advertisements.
Green agreed some people might find it strange for a boxer to speak out on the issue but said his sport was a world away from the violence taking place on WA's streets.
"I chose to do this in a governed playing field against an opponent who has signed on to do the same thing," Green said. "But these young guys might take notice from someone who is actually a fighter and who is saying 'this is ridiculous and it's gutless'.
"I feel very strongly about the fact that people are being killed or severely maimed for no reason.
"There seems to have been a shift in the way younger people are thinking and a lack of respect and old-school values."
Martin Wilson from Soul Films, who shot the advertisement, said another four had been scripted to look at the wider ramifications of one-punch attacks.
The company pitched the advertisement to the Government almost six months ago in a bid to attract funding to air the campaign.
Premier Colin Barnett said he had not seen the advertisement but he supported the message.
"It is a cowardly thing to do to walk up behind someone with a king-hit and we've seen fatalities arise out of that," he said. " It would be great if the media ran the campaign but the Government had not given a commitment to fund it.
Professor Knuckey said the medical consequences of one-punch attacks ranged from mild, such as concussion, to severe, such as fatal swelling of the brain.
