In March the same year, Alexandrovskaya/Windsor competed at the 2017 World Junior Championships in Taipei, Taiwan. Ranked third in the short program and second in the free skate, they finished first overall, outscoring the silver medallists, Aleksandra Boikova / Dmitrii Kozlovskii of Russia, by 2.05 points. They became the first skaters representing Australia to win gold at one of the ISU Figure Skating Championships and the first to finish on a podium at Junior Worlds since 1976, when Elizabeth Cain / Peter Cain took the pairs' bronze medal.[16][17] A couple of weeks later, the pair competed at the senior-level World Championships, which took place in Helsinki, Finland.
