Students and teachers from Riverside High School braved the clippers and have raised more than $1900 so far with their Mullets for Mental Health fundraiser.
The event held on Thursday had 17 students and two teachers undergo the chop to start conversations on mental health and raise money for R U OK?.
Year 10 student and initiator of the fundraiser Jordan Cowell said the event was a great way to start conversations around mental health as everyone loves a mullet.
"I think it's very important to make sure we reach out to people and make sure everyone is doing okay and make sure we ask people 'are you OK'," he said.

"Getting people to sign up and actually get the cut in front of the whole school is quite a big thing to do so very proud of the school for that."
Students and teachers rallied behind those brave enough to get the cut, with cheers and laughter filling the hall periodically during the event.
Principal Natalie Odgers said the fundraiser was driven by the students.
"They initiated it. They've organised it all and driven it all," she said. "There's a sense of fun about it and lots of teachers have joined in as well, so I think that's added to the atmosphere."
Jesse Egan, year 10, said he participated as he had the hair to do it and it was for a good cause.
"I think it's good because I know a lot of kids suffer with social media, and bullying in general, so I thought it was a good cause to support," he said.
The goal for the Mullets for Mental Health fundraiser is $3000.
