Australian Emma McKeon could bow out of Tokyo 2020 on Sunday as the first female swimmer to win seven medals at a single Olympics.
No Australian has ever won that many in one Games and Russian gymnast Maria Gorokhovskaya, in 1952, is the only woman to have achieved seven in any other sport.
McKeon goes into Sunday's action with five medals already from Tokyo — two golds and three bronzes — to equal the Australian record.
