Born in Suva, Fiji, Saville moved to Alice Springs, Northern Territory, Australia, at a young age. She developed her cricketing talents in the Northern Territory, and was often the only girl playing in the side. In early 2016, she was selected in Cricket Australia's Talent Squad after impressing at the under-18 National Championships, in which she represented South Australia.[3][4][5]
Saville's potential was also recognised by South Australian Scorpions and Strikers coach Andrea McCauley. In the lead up to the WBBL|02 season (2016–17), she was added to the Adelaide Strikers' squad, as its youngest member.[3] She made her debut for the Strikers on 2 January 2017 against the Sydney Sixers, and her first significant contribution to the match was the catch that dismissed star Sixers player Ellyse Perry.[5]
