Georgie Robertson Stone OAM (born 2000) is an Australian actress, writer and transgender rights advocate. At the age of 11, Stone was the youngest person to receive hormone blockers in Australia, which set a precedent that eventually changed the law that compelled transgender children and their families to apply to the Family Court of Australia to access stage one treatment. She continues to advocate for transgender children, and is one of the most visible transgender people in Australia. She is also known for her role as Mackenzie Hargreaves in Neighbours.
