Stone began filming her scenes in June, with the episodes to be aired later in the year. Stone described Mackenzie as "a bit world weary, a bit cynical, a bit hardened by her experiences". She also described her as "sweet, compassionate and lovely" when she opens up to other people. In September, it was announced that Stone would appear in a spin-off titled "", reprising her role from the main show. The series will be released on My5 and 10 Play in November, and consists of five episodes that "explore issues universally troubling teens today – bullying, mental illness, sexuality, cultural diversity, parental and peer pressure, and teacher-student relationships." On 19 October 2019, it was announced that Stone would be promoted to the regular cast in early 2020. Stone lives in Melbourne, Australia. She has a twin brother, Harrison. Stone was vocal about her gender identity at two years old, finally affirming her gender at age 8. Stone commenced taking puberty blocking treatment in 2011, the youngest in Australia to commence stage-one treatment (she was 10 at the time). In 2015, she commenced hormone replacement therapy, at age 15. Since 2014, Stone has been public about her gender identity. In 2016, she won GLBTI Person of the Year from the GLOBE Community Awards, and the Making a Difference award from the Anti-Defamation Commission, the youngest recipient of both. Stone was featured in the list of "25 LGBTI Australians to Watch in 2017" by the Gay News Network at the end of 2016. In October 2017, Stone was announced as a finalist for Young Australian of the Year in Victoria, eventually winning the award on 26 October. Stone was announced as a finalist for the Human Rights Awards in November 2017. She was announced as the winner on 8 December.
