Star swimmer Cate Campbell describes her lifestyle as one of a grandma hermit.
Most 21-year-olds wouldn't be satisfied with that, but Campbell says if it gets her to where she wants to go, it will all be worth it.
Campbell burst on to the scene as a teenager but has been held back by illness and injury.
She was part of the 4x100m relay team which won Australia's only gold medal in the pool at the 2012 London Olympics before a bout of pancreatitis stopped her competing in her pet individual event, the 100m freestyle. Campbell said she used the pain of that experience to win the 100m free-style world title in Barcelona.
It was one of four medals for the Queenslander at the April championships.
"London was heartbreaking," she said. "I was watching four years' worth of work go down the toilet, literally.
"At the same time, I used that as a motivator. I got straight back in the pool and I really felt like I had a lot to show the world because I didn't get to show them what I could do in London.
"If I hadn't been sick in London, maybe I wouldn't have done as well at worlds this year."
Now Campbell is chasing Olympic gold in Rio in 2016.
She will be a key figure in bringing the feel-good factor back to a sport which has been mired in bad publicity in recent times.
Campbell is excited about the appointment of a new head coach, Dutchman Jacco Verhaeren.
She has met Verhaeren in the past as the coach of her main rival Ranomi Kromowidjojo and said she had always had the highest respect for him.
Campbell is in Perth to promote the BHP Billiton Aquatic Super Series at Challenge Stadium, now 100 days away.
It will be one of her first races since Barcelona.
"I have always loved racing outdoors but we hardly ever get to do it and to race under the elements is so much fun," she said.Campbell will be in Forrest Place from noon today to launch the series and meet fans.
