Australia's golden girls are heavily favoured to win a third-straight gold medal in the 4x100m freestyle relay at the Tokyo Olympic Games - and their journey starts tonight.
"It's honestly a real honour and a privilege to be a part of this relay team," swimmer Cate Campbell said. "It's been one of the highlights of my career."
"You have to trust that you've done the work, that I know how to do this and that I can execute it when it matters. And history shows that I can. So it's a lot of preparation and then self-belief on the day."
Here are the Australians to watch on day one.
Softball: Australia look to continue their momentum against Canada at Yokohama Baseball Stadium from 11am.
Hockey: The Kookaburras head to Tokyo on top of the world rankings, but they've got the weight of the world on their shoulders leading into their opening game against Japan at 10.30am.
