Whack! Ash Barty was four years old when she hit a powerful shot at the head of her tennis coach. He said she wasn’t old enough to play but he saw how determined she was.

Since then, she’s whacked millions of tennis balls and travelled away from home for months at a time to practice and play. Until, finally, she became the number one female tennis player in the whole world.
