Amanda Chartelow first appeared in Last Term at Malory Towers. Amanda is a huge 'strapping' athlete, who makes Mam'zelle Dupont feel quite intimidated. She is extremely good at sports and joined Malory Towers because her old school, Trennigan Towers (a famous sports school), was burnt down, so she had to find somewhere else. She plans to enter the next Olympic Games. Amanda becomes disliked by the other girls because she criticises the sports at Malory Towers.
She coaches June in tennis and swimming, but they argue and stop the coaching sessions. They dislike each other, until Amanda goes swimming in the sea and has to be rescued by June.
