Australia's Olympic and world swimming champion Giaan Rooney has announced her retirement from competition.
Rooney, 23, said she was hanging up her goggles to begin a new career as a television presenter.
"I don't think you can ever replace the feeling of standing up on a block at an Olympics or world championships," she told the Australian Nine Network.
"But for me, I get the same kind of adrenaline feeling of being in front of a camera, that I do when I'm about to race.
"That tells me I'm heading in the right direction and that the next step is the right step."
Rooney crowned her sporting career with a gold medal at the 2004 Athens Olympics when she swam the backstroke leg in the Australian women's medley relay team that broke the world record.
