The first group of Australian swimmers arrived in Perth yesterday for the world's richest swim meet - the inaugural Aquatic Super Series at the weekend.
For most, it will be their first real competition since last year's London Olympics when the team swam below expectations.
Most of the swimmers took some time off after the Games, but are now back in serious training as they aim to win national selection for the world championships in Barcelona in July.
For London gold medallist Cate Campbell, this weekend's event is an opportunity to measure the progress of her fitness and strength training, but to also catch up with colleagues she has not seen since the Olympics.
The opportunity to win some money is a bonus.
"And it's hard to believe it's all happening in Perth - in front of a home crowd," the 20-year-old freestyler said. "Usually we have to go overseas to race competitors of this standard. It's going to be unbelievable."
Campbell, who won gold in the 4x100m freestyle relay, is part of the 30-member Australian team that will take on swimmers from China and South Africa for a share of $500,000, starting on Friday. Winners of individual races will get $2500 with other cash prizes for second and third.
Winning relay teams will share $8000, while the male and female swimmers of the meet will win $15,000 each. The winning country will collect $100,000.
