The 10-year-old Cudgegong Valley Primary School student will be cutting his hair on July 9 and donating it so it can be turned into a wig.

"I just wanted to be different to everyone else. Someone suggested I get it cut to use as a wig for someone suffering from cancer and I thought it was a nice idea as we have had close family and friends affected by cancer so I went with it," Dusty said.

Dusty's mum, Leonine, said she was hardly surprised that her son wanted to do something so caring because it's 'just the kind of kid he is, always thinking about others'.

"My husband and I are very proud of Dust, he has gotten a few negative comments about his hair but he didn't care, he had a goal and didn't give up.

Leonie, as well as Dusty's siblings, admit they will be glad when the hair is all gone because it's 'everywhere', but Dusty says he's more excited than anything.

"It has been fun growing my hair but it's a lot of hard work. I am very excited about getting it cut off because I know that I'm doing something good for people with cancer," he said.

"It's important to help people in need because you never know if it could be you or someone you love in the same situation, and doing something little like this could help them feel good and that someone cares.

"During this process I have been mistaken a lot for a girl but I have laughed it off, it has been fun growing my hair. I'm not concentrating on what I'm doing, I'm concentrating on what I can do for others."

Although Dusty is unsure if he will do this again, he said there are many ways people can help.

"I don't think people specifically should do this, there are many other ways you can help like donating to cancer research or even make a card or by telling a joke," he said.
