The hosts recorded the highest chase at the Gabba as they scored 309 for three with one over to spare, to take a 2-0 lead in the five-match one-day international series.
"We had found out in Perth that our bowling attack has had less games than Mitchell Johnson by himself. So it is a real credit with the way the guys are applying themselves. They are training hard and learning from everyone, using all their resources and fighting it out in the middle," said Finch after the seven-wicket victory.
"It is great to see. It was really exciting for the boys and it is about the guys learning with the ODI World Cup three and a half years away. There is a chance to experiment and get games to the guys, and the selectors are thinking about that," he added.
Finch (71) put on a 145-run partnership with Shaun Marsh and the duo set the stage for Australia's successful run-chase. At one time though they were under pressure with the asking rate climbing up to seven per over, but they soon came out all guns blazing to unleash a flurry of boundaries.

India had scored 308 for eight thanks to a second consecutive hundred from Rohit Sharma. However, there was cause for some controversy, as he was given not out when he seemed to have nicked behind at the score of 89.
"I would like to see consistency around the world, either it is used or it is not. But in the end of the day India have got the right to make a decision. If the ICC makes a blanket rule that everyone has to use it, then there would be no debate about it. But they are still giving teams options and so I don't think it is going to change anytime soon," he added.
"We have always had confidence that we can chase down any total. Compared to our bowling line up, our batting is quite experienced. We have guys who have played here as a team for quite some time now. When you look at a chase of 309, you still have to bat unbelievably well. Here the ground is so big, it is not a power game. So you have to adapt you game slightly and make it a running game. You have to still pick up a boundary at the same time but have to be creative in how you chase it down," he said.
