Born on the Gold Coast, Mackenzie Arnold made her debut for the Matildas in 2012 at age 18. Over the following decade, Macca has risen to the top as number one goalkeeper both at an international level and throughout her Australian W-League career. In 2023, Macca's heroic performance in a record-breaking 7-6 penalty shootout against France to secure the Matildas a spot in the FIFA Women's World Cup semi-finals was watched by millions of Australians. In 2024, Macca will put on the gloves at the Paris Olympics, where the Matildas will go for gold. Nicknamed the Brick Wall and Australia's Minister of Defence, she is currently goalkeeper for Portland Thorns FC in the United States.
