2018 Winter Olympic Australian figure skater Ekaterina Alexandrovskaya died on Friday of causes that have not been disclosed.
Alexandrovskaya was a Russian-born naturalized-Australian who first rose to prominence alongside her figure skating partner Harley Windsor at the 2017 World Juniors. They are so far the first and only Australia figure skating world champions.
Both athletes then proceeded in qualifying for the 2018 PyeongChang Olympics, Windsor becoming the first Indigenous Australian to compete in the winter games.
They finished 18th overall.
However, the journey would end soon after for the young pair after Alexandrovskaya was forced to retire from the sport last February due to continued injury concerns.
Windsor expressed his deep sadness about his former partner's passing on Instagram:
"Words can not describe how I feel right now, I am devastated and sick to my core about the sad and sudden passing of Katia. The amount we had achieved during our partnership is something I can never forget and will always hold close to my heart. This news is something you can never prepare for. Rest In Peace Katia."
Alexandrovskaya was 20-years-old at the time of her passing.
