Born in Tallangatta in Victoria, Australia,[1] Lyon began skating with the Victorian Roller Derby League in Melbourne in 2008.

In 2010, she moved to Cardiff in Wales, where she played for the Tiger Bay Brawlers, then she returned to Victoria in 2012.

[2] While Victoria played roller derby at the highest level, Lyon found the expense of regularly travelling to the United States to compete to be too high.

She again competed for Australia at the 2018 Roller Derby World Cup, at which the team took the silver medal, and Lyon received the Most Valuable Player award.

Six feet tall, she has described her playing style as trying to embody the concept "stay low, get lower".
