Swimming sisters Cate and Bronte Campbell have each
praised the other as the reason they'll both race at the London Olympics.
Cate would have quit swimming if not for her little sister; and Bronte says she would never have been an Olympian if not for her big sister.
The sisters have become the first siblings to make Australia's Olympic swim team in four decades.
Cate, 19, won the 50m freestyle in 24.44 seconds with 17-year-old Bronte second in 24.61s at the selection trials in Adelaide on Thursday night.
"I don't think they make words to describe that," Bronte said of the one-two finish.
"It was the most amazing thing that has ever happened in my life."
Cate won two bronze medals at the 2008 Beijing Olympics but would have quit swimming two years later when suffering post viral fatigue - if not for her sister, who "was the one that got me out of bed".
"She went through exactly what I went through," Cate said.
"To be down in the dumps with someone and then the highest of heights with someone is a really incredible experience."
The sisters will be the first siblings to swim for Australia at an Olympics since 1972 in Munich when Neil and Greg Rogers and Narelle and Karen Moras competed.
"What can I say, it's pretty rare to have two high calibre athletes in one family, and to peak at the same trials, it's just incredible," Cate said.
Their joint Olympic dreams brought an end to any sibling rivalry, she said.
"We train together and race together so often we have just had to shut down that side," Cate said.
"We're best of friends, so it doesn't really matter."
Bronte said the only wins she has against her older sister was on Wii tennis - "she's not that good, she doesn't get the wrist movement right, but she beats me at pretty much everything else".
But she planned to lean heavily on the more experienced Cate at the London Games.
"She has been there and set that example," Bronte said.
"And now we're going to London, she knows what it's like to compete internationally, I have no idea, and she is going to show me the ropes."
