The battle for T20I supremacy begins with the series opener in Canberra on Wednesday, October 29.Badrinath picked the in-form Abhishek Sharma as his first player, thanks to the latter's sensational T20I form. The young opener is coming off a phenomenal run in India's most recent T20I assignment - the 2025 Asia Cup.Abhishek led all scorers with 314 runs at an average of 44.85 and a strike rate of 200 in seven outings, earning him Player of the Tournament honors. The southpaw is currently the No. 1-ranked T20I batter in world cricket.Badrinath picked the woefully out-of-form skipper Suryakumar Yadav as the next key Indian player for the Australian series. Surya has been shockingly out of form in T20Is since the beginning of last year, averaging 21.16 in 30 matches with four half-centuries.The numbers have worsened since he took over as India's permanent T20I captain, following the World Cup last year. Surya has averaged a dismal 18.33 in 20 innings, including only 18 in the recent Asia Cup in the UAE.Yet, the Men in Blue have thrived as a team under Surya, winning 20 out of their 22 T20I matches.S Badrinath picks one of the bowlers as his final Indian player for the Australian T20IsSubramaniam Badrinath picked wily spinner Varun Chakaravarthy as the final name on his three key players list for India in the upcoming Australian T20Is.
