She was included by coach Philip Doyle in the squad for the disrupted 2020 Women's Six Nations Championship. During the championship, she started for Scotland in the match against England, replacing Megan Gaffney. For the match against Ireland she was a substitute for Chloe Rollie at full-back. Doyle explained his decision, "Evie Tonkin played well at full-back in Spain, but this is such a big game and Chloe’s experience will be invaluable."
