Sam Thaiday is no stranger to big challenges. From his days as a powerhouse on the rugby league field to his infectious personality on TV, he’s always tackled life head-on. Now, he’s taking on a whole new challenge. Going blonde for the World’s Greatest Shave, before taking the ultimate plunge and Shaving it all off for a cause that’s close to the hearts of many. We’re thrilled to welcome Sam as an official ambassador for the World’s Greatest Shave 2025! 

A legendary transformation for an unstoppable cause

Sam is kicking off his journey by Colouring his hair blonde. It’s a bold move, but one that will make a real difference to families facing blood cancer. He’s then taking it one step further, as he plans to ultimately Shave his head for the cause.  

Sam’s support shines a light on the thousands of Australians facing a blood cancer diagnosis every year. With more than 150,000 people living with blood cancer in Australia right now, the need for research, support, and awareness has never been greater.

Why Sam is Shaving for a cure

For Sam, becoming an ambassador isn’t just about the Colour or Shave for cancer – it's about the impact his involvement can make. Blood cancer can affect anyone, at any time, and treatment can be long and gruelling. The Leukaemia Foundation provides critical support services for individuals and families facing a blood cancer diagnosis, ensuring no one has to go through it alone. 

As a dad, Sam knows how important it is to protect and support Australian children. When he discovered that blood cancer is the most commonly diagnosed cancer among children,  he felt compelled to take action. 

By stepping up as an ambassador, Sam is calling on fellow Australians to Shave, Cut or Colour their hair alongside him and raise funds that will fuel life-changing support for patients and families, and groundbreaking research projects. Whether it's a buzzcut, a chop, or a splash of colour, every dollar raised makes a difference.
