Meet Quincy. She's learned to surf when she was four, because she wanted to be like her dad.
She's six now and she's really freaking amazing.
“The very first time I saw her out in the ocean she changed, she became a complete person,” Quincy's mum, Kim, told ABC Open.
Quincy has a condition called Congenital Adrenal Hyperplasia, which affects her body's ability to create cortisone, and needs medication three times a day - but she doesn't let that stop her from doing anything.
She not only surfs, she also skateboards, because why not?
She says when she grows up she wants to be a professional surfer AND skateboarder.
