In 2009 Wiasak represented Australia in Lithuanian World Games competing in women's basketball. After missing out of selection to compete at a major international Games at the Glasgow 2014 and Rio 2016, Wiasak was selected for her first Commonwealth Games. At the 2018 Gold Coast Commonwealth Games, she set a new Australian record beating her previous national record set at the Paris 2015 track world championships, and Wiasak was one of four riders to beat the previous Commonwealth Games individual pursuit record Joanna Rowsell set in 2014.
