The 17-year-old Methodist Ladies’ College student won gold with partner Tenille Falappi, from Queensland, who crossed the finish line at 35.344sec to mark their record time.
Tian also won bronze in the time trial of the women’s 500m in 36.132sec.
‘Junior worlds was a highlight, getting to know team-mates and being part of one of the best teams I’ve been in,’ she said.
‘I really feel I grew up and matured a lot while I was away.’
While an upper respiratory infection cut short Tian’s time at the championship, she said her four-week recovery spent travelling around Europe with her parents was incredible.
She said she was now focusing on training for her first year in the senior nationals in January.
‘I’m really looking forward to it because it will be a bit of a step up for me but I’m not putting pressure on myself, I’ll just give it my best shot.’
