Australian guard Patty Mills says the Boomers hope to have some surprises for their Olympic opening round opponents Brazil.
While Brazil beat the Boomers 87-71 in a warm-up match in France on July 23, Mills says the Australians kept a lot of their cards close to their chest.
"It was a tricky situation because the exhibition game was scheduled before our actual London schedule had come out," Mills told reporters on Wednesday.
"On purpose we didn't play the way that we want to play, we are kind of saving it for the real deal.
"There are still a lot of things we can learn from that game and definitely we learned a lot about what they can and can't do."
The match was scheduled for day two of competition.
The Boomers were hoping for a better start to their Olympic campaign compared with previous Games, having lost every opening match since Atlanta 1996, when they beat South Korea 111-88.
London is Mills' second Olympics, having represented the green-and-gold at Beijing four years ago, and the 23-year-old who plays for the NBA's San Antonio Spurs, said he hoped to provide some leadership in a team full of veterans.
"I think it is great for me and I am grabbing it with both hands and really taking it on," Mills said.
