Cate and Bronte Campbell became the first Australian sisters to win gold in the race, and while hard was a major factor behind their win, the siblings from Brisbane also credit their brother, who has cerebral palsy, as their inspiration.
Bronte previously said she handles the pressure of competition by thinking her brother Hamish.
'I always think about stuff like this [Hamish's disability] when I get up behind the blocks for a race. It's not life and death and that’s something that Hamish has helped me realise,' Bronte told Fairfax Media.
She added, 'It's given me some perspective. It’s a swimming race and it’s really, really important to me but there’s only a few other people in the world who really care about this and no one’s going to get hurt if I fail except for maybe me, so it’s definitely helped me relax going into competitions.'
Mother Jenny, who remained in Brisbane to care for Hamish, 17, told the Seven Network, ‘This has been a dream for so long and it’s come true.’
‘It almost seems unbelievable that I have two daughters who stood at the top of the podium at the [Olympics], doing what they used to talk about doing 15 years ago.
‘Right from when they were very little – just nine and seven – and they started swimming, they would get up at 6.30 in the morning … and they walked up to the swimming pool.
‘It was just so exciting and all four girls [in the relay team] did really, really well.'
Hamish was thrilled to hear his sister’s had won a gold medal, Jenny added, ‘He loved hearing the national anthem. He’s thrilled.'
