Former Australian coach John Buchanan, who joined the world champion team in 1999 with an "error-free" mantra, said the players were still to play a flawless game but were motivated to pursue pefection.
Buchanan said the Australians may not have a perfect game but they have a perfect team, which was always motivated to improve itself despite a number of records to their name.
"We haven't played the perfect game (yet). But we do have the perfect team, one that constantly tries to improve itself, individually and collectively," Buchanan said.
He said Australia's pile of spoils grew but motivation never waned. "If it had, it might have meant we had the wrong players, if they needed some form of reward, punishment, external incentive," he said.
"It hasn't been about motivation. It's been about creating an environment for a group of players who want to improve themselves all the time.
"We've never compared ourselves to our opposition. We would look at our opposition as preparation. But our comparison was always with ourselves. That's one of the key reasons the Australian team is different," he was quoted as saying by The Age.
Coaching an already world champion side was not a easy ask but Buchanan believed there was always room for improvement.
