In 2017, Carpenter competed with the Matildas at the Tournament of Nations in the United States. The Australians won the tournament after a 6–1 win over Brazil. During the 28th minute of a match against the United States, Carpenter was hit directly in the face by a ball being cleared by American defender Crystal Dunn. Carpenter dropped to the ground and was later taken off the field by medical staff. Playing with gauze up her bleeding nose, she returned to the field to help the Matildas secure a 1-1 draw against the 2015 FIFA Women's World Cup champions.
