Australian swimmer Shayna Jack was driven by anger, pain and injustice.
Now vying for her third Commonwealth Games appearance, the Paris Olympic gold medallist has found new motivation: swimming in Glasgow with younger brother Jamie.
Australia's 42-strong squad for this year's Games will be decided from Monday in the week-long trials at Sydney Olympic Park, with selection for the Pan Pacific championships also on the table.
Freestyle swimmer Jack will be just one of many heavyweights in the Sydney pool, joined by Mollie O'Callaghan, Kaylee McKeown, and an in-form Lani Pallister.
Pallister has set herself an audacious program, racing in the 100, 200, 400, 800 and 1500 freestyle events.
Cameron McEvoy - 50-metre freestyle world record holder - headlines the men's field, alongside Kyle Chalmers and Zac Stubblety-Cook.
