Colebourn had been competing on the European circuit since December 2018, with a goal of earning under 180 points. Earning 150 points would've granted her qualification to the 2019 IBU World Cup, but she was able to score 137.56, comfortably sending her to the World Cup.
Currently, the 24-year-old is in Ostersund, Sweden, looking to make more Aussie history as she represents the green and gold at the World Championships.
