A joint statement by the Australian Paralympic Committee and Australian cycling federation said that Greco "passed away in her Adelaide home after experiencing a sudden medical episode" on Sunday.

Greco, who was born with cerebral palsy, won the first gold medal of the pandemic-delayed Tokyo Paralympics in 2021, breaking her own world record in the women's C1-3 3,000-meter individual pursuit.

She went on to add bronze medals in the road race and time trial.

Greco also won multiple world championship titles and World Cup medals, after bursting onto the para-cycling scene with three world records, two gold medals and a silver at the 2019 track world championship — just a year after switching to cycling from para-athletics.
