Private Sydney boy's school bans students from wearing mullets

It's one of the world's most recognisable and ridiculed haircuts, but now the mullet is fast becoming rejected by schools.

Waverley College in Sydney is the latest educational institution to rule the 'do often described as "business at the front and party at the back" inappropriate for its campus.

"A lot of people are getting it," Kim Van Heel from Ziggy's Barber Salon said of the mullet.

"I doesn't matter if you're old, young, every one is seeing it as normal now."

The popular barber shop saw requests for mullets grow throughout the COVID-19 pandemic.

"Everyone started realising they can grow their hair out," Ms Van Heel said.

"When you're working from home there is less pressure.

"Then they realised you can go shorter on the sides but still have fun at the back like Billy Ray Cyrus said."

The haircut was known as an 80s and 90s staple with rock stars like David Bowie, John Farnham joining the country star Cyrus in leading the craze.

Australia's footballers also caught mullet mania.

Now, three decades on, the hairdo has infiltrated the once stuffy world of professional golf.

"It's become a good luck charm," Australian golfer and world number 27 Cameron Smith said recently showing off his longer locks.

"It needs a bit of a trim at the front.

"I'd really like to go full business at the front and party at the back."
