The loss of the 1-2 ODI series reiterated that India have more work to do in 50 overs but they have a less balanced side.
Before the epidemic discontinued sports activity around the world, India vacated host New Zealand in a five-match series and they will take a lot of confidence from that result in the match against Australia.
The presence of Washington Sundar, Deepak Chahar and T Natarajan, who performed well in ODIs on Wednesday, gives the bowling department a much-needed balance.
Sunder is more confident after Royal Challengers Bangalore and Indian skipper Virat Kohli were effectively used in the powerplay and middle overs after the IPL.
Since Hardik Pandya did not bowl regularly, India had only one specialist all-rounder in ODI Ravindra Jadeja.
However, in the T-20s, Kohli also has Sundar’s services in both divisions and is likely to roll up his sleeve for a brief spell as Hardik did from the second ODI.
Yorkshireman Natarajan, who was a late addition to the one-day squad, could make his T20 debut on Friday with plenty of promise.
Unlike the SCG, the Manuka Oval Surface had plenty for spinners and speeders. It will be interesting to see who opens the bowling with Jaspreet Bumrah as the toss up between Mohammad Shami and Deepak Chahar.
Yuvvendra Chahal, who had an unforgettable outing in ODIs, is also expected to bounce back.
In the ODIs, he was batting fifth. Rahul and Shikhar Dhawan are expected to return to their preferred starting slot.
The in-form wicketkeeper batsman was also open in the previous series against New Zealand and is expected to bat more than 20 overs as he has performed well in the IPL.
Skipper Kohli is well-connected in ODIs and aims to build on that, but fourth-seeded Shreyas Iyer will be aiming for big scores from a good start, as he did in the previous three-match series.
As Kohli said, an unofficial third ODI win was the result they needed before the T20 series, otherwise the tour would have been tough.
After naming a single team for Australia, ODIs and T20s, they are backing up to beat India after a clinical performance in the last week despite injury concerns.
Star batsman David Warner is unavailable due to a groin injury and it remains to be seen if Marnus LaBuschagne will return with captain Aaron Finch on Friday night.
Marcus Stoinis was another good starting option with Finch but he is also a doubtful starter due to a lateral injury he suffered in ODIs.
Pat Cummins and Michelle Stark, who rested on Wednesday, are expected to return to bolster the attack.
