Amoe-Tarrant was born in Nauru and lived there until she was 12 years of age.
Her mother died of kidney problems in 2009, so she and her siblings were adopted by their grandparents, who brought them to Australia.
Four years ago, Amoe-Tarrant won a silver medal for her country of birth, and now the 23-year-old has one as an Australian.
