There is no change in the top three all-rounders, with Maxwell leading the field.
Australia's climb up the Twenty20 rankings has been halted by a red-hot Pakistan, losing their tri-series final in Zimbabwe by six wickets.
Aaron Finch's team posted a competitive total of 8-183 at Harare Sports Club and looked to be on track for a memorable victory by taking two wickets in the first over.
But the left-hander had played a pivotal role a match earlier against the home side with a 42-ball 46, ensuring captain Aaron Finch received the lion's share of the strike in their 223-run first-wicket stand, the biggest partnership in T20 worldwide history.
Rahul's scores of 70, 101 not out, six and 19 in last four T20I matches have helped him move up nine places to a career-high third position.
"It's a great team effort, credit to the bowlers", Pakistan captain Sarfraz Ahmed said. "There were some dropped catches but we took the momentum in the second innings".
In reply, Pakistan did not get to the best of starts with Glenn Maxwell sending Sahibzada Farhan and Hussain Talat back to the pavilion.
Australia and Pakistan had already qualified for Sunday's final after both won three matches each.
Zaman shared in a century stand with Shoaib Malik as Pakistan recovered from an early wobble in their pursuit of Australia's 183 for 8, and Malik then showed all the experience of an 18-year worldwide career to see his team home in their highest ever successful T20I run chase with an unbeaten 43.
Mire started the tri-series with a big reputation but not much in terms of numbers in T20I cricket, but nearly single-handedly kept Zimbabwe hoping for a spot in the final with two magnificent innings.
"Learning from failure and working hard are important factors for me", he said, adding that he received help and guidance from senior player Shoaib Malik. "Hard work in nets is the main thing".
Additionally, with Finch being at the centre of the action on both tours, there remains the likelihood the big Victorian could assume the captain's role across both limited-overs formats.
