Australia captain Ricky Ponting insisted his team would continue to strive for perfection despite the ease of their 10-wicket win over Bangladesh.
Ponting was not needed with the bat but took two neat catches
"We are playing well, and it was another good game today, but it's only early days and we have to keep improving," Ponting said.
"We knew Bangladesh would come at us early on but the bowlers hit their spots and did a good job.
"The batsmen have been in form and they just played properly and hit the gaps."
Ponting is determined to ensure the Australians do not become complacent given the number of matches still to play in the event.
Matty Hayden's in really intimidating form at the moment - to be part of that partnership is really pleasing
After their second comfortable victory in the Super 8s, the Australians are next in action on 8 April against England and have three more matches in the phase after that, the last of which is on the 20th.
"We've been playing well ever since the warm-up matches in St Vincent," the 32-year-old captain said.
"We wanted to carry that through to the tournament and we have done that. But it's still early days.
"We have to make sure we keep it going for the next few weeks."
Adam Gilchrist was also delighted with the team's position in the early stages of the Super 8 phase.
"It's been a great start and things are moving really well for us as a team," said the stylish left-hander, who recorded his 50th one-day international half-century.
"The bowlers have been outstanding, and Matty Hayden's in really intimidating form at the moment - to be part of that partnership is really pleasing."
Asked whether the team scored the runs deliberately quickly to enhance their run-rate he said: "It was more to do with the black clouds we could see in the distance.
"If you are winning matches, run-rates tend to take care of themselves anyway," he added.
Australia were, however, critical of mopping up arrangements at the Sir Vivian Richards Stadium after the start of play was delayed for five hours.
"At the end of the day, we were lucky to get a game in today. We didn't see enough hands on deck out on the ground," said Ponting.
"I know they had a machinery breakdown which didn't help things, but I went and spoke to the umpires at one stage and they said the groundstaff were on their lunch break. That was a little more time that was killed."
